Ultimate Guide to Datetime! Python date and time objects for beginners
HTML-код
- Опубликовано: 2 июн 2024
- Hi everyone! today we will talk about the Datetime module, which helps us load and manipulate date and time data in Python. The main reason why Datetime is so important is because Python doesn't really have a built-in data type for dates (and times) 🗓️⌚- but we can easily import them from the datetime module! 😀
So in this tutorial - we will discuss and experiment with the most important commands from the documentation, focusing on 3 different classes: date, datetime and time.
We will learn how to create and manipulate each of these and we will also convey them with different formatting methods.

Hi There. Just a comment. Regarding printing format strings, I gonna say this is better and easier: { print(f"Today is: {today}") }
Thank you so much for your tip Aziz! 😀
@@PythonSimplified It's a pleasure. Your vids always are crystal clear
I think it's more common like that
disagree.
f-strings shine when one passes word-like variables such that the f-strings reads like a proper sentence.
things start to go south very quickly however once one starts to pass function calls.
this is precisely when `.format` method starts to shine.
so you see, neither one of them is better than the other, they complement each other.
allow me to demonstrate:
```
from datetime import date
def verify(f):
def g(wd: int) -> str:
assert 0 str:
return {
0: 'Monday',
1: 'Tuesday',
2: 'Wednesday',
3: 'Thursday',
4: 'Friday',
5: 'Saturday',
6: 'Sunday',
}[wd]
@verify
def daycat(wd: int) -> str:
return 'weekday' if wd < 5 else 'weekend'
@verify
def action(wd: int) -> str:
return 'time to go to work' if wd < 5 else 'time to chill'
wd = date.today().weekday()
print(f'Today is {weekday(wd)}, {daycat(wd)}. {action(wd).capitalize()}!')
print('Today is {weekday}, {daycat}. {action}!'.format(
weekday = weekday(wd),
daycat = daycat(wd),
action = action(wd).capitalize(),
))
```
and yes, you could extract all these function calls outside, but you would not only have to come up with new names for the variables, but you would also unnecessarily pollute your namespace, assuming you would only need these function call one time.
@@michalbotor Thanks Michal
I used datetime module several times in my python projects but always looking for solutions to specific situations and I've never tried to arrange my knowledge. Thanks a lot for this video. It is really helpful. I discovered your channel few weeks ago and it will surely be one of my favourites
Thank you so much!!! I have been struggling with writing the middle of a program for 2 months. After following the steps in your video and struggling with line 50 to discover my system had to have string properties assigned to add timezone offset I went to my program assigned my date object as a string and my program worked. So simple but so much grief. Would have never found it without your video!!!
yes, we can do!
from datetime import datetime
user = user.datetime()
start = user.strftime("%m/%d/%Y/%A, %H:%M:%S:%p")
print("Date & Time:",start)
your tutorial is easy to understandable :) and thanks for this.
Bingo! I just spent so much time trying to figure this out and your video cleared it up really quickly. Thanks
I don't know if I haven't looked for more channels but I think this is the first blog about python done in a more fluid way. Thanks for giving us this, I really need to practice
Thank you so much for your lovely comment Luis! 😀
Supper happy to help! 😊
It's difficult to understand how being almost 3 am you look so plenty of energy and shining (every square centimeter of your face) You are awesome Mariya Sha!! I can't find anything for complain. UR Simply a perfect teacher, trainner and RUclipsr. You find the way to build the bridge between learners and the new knowledge.
Dear Mariya, thanks for all your videos. They are awesome! Keep up the good work. 🥳😊
Excellent video as always,
full of useful information! Thanks!
תודה! 😀
Thank you so much Balazs! Super happy you liked it! 😁 בכיף!
I have struggled with Python's date and time methods. This video was really helpful for me. Thanks!
Thank you so much for the lovely comment, Lars! 😀
Super happy I could help! 😊
Clean and fast code, I love it. Belated happy birthday too XD
Your tutorials very clear and understandable! Thank you!
Thank you so much Slon! Glad you like them! 😊
Quite the tribute @5:49! That caught my attention as everyones favourite electrician. 😎
I knew you will appreciate it!! 😀
Wow! So glad I found your channel! This is super helpful!
Thank you so much Sherry! Super happy to help!! 😊😊😊
Thank you! Very useful! ❤
Thank you so much! I'm super happy to help! 😊
Very cool tutorial, I like how you're concise and to the point.
Спасибо. Очень хорошая подача. Нет "воды". Классно.
Спасибо большое! рада что вам понравилось! 😀😀
Wow, I followed you great up until Your line #50, I got errors there googled and googled and could find no help for my error. I thought my version of python was different than yours, I added a date and used datetime and it worked great. Tried a lot of other things too, finally entered it as: "my_time=time.fromisoformat(str("15:33:08-07:00"))' and wham it worked!!! My system with time must have read the "-" and stored something as an integer, Just had to tell the program that this is a string. You have wonderful energy and do an excellent job of converting high tech into common English, a rare gift. Thank You so much!!!!
Excellent. Great as always.
Very good presentation. Thanks
Happy birthday^^ Thank you so much for lots of great videos!!
Thank you so much Jong!!! 😁😁😁
Very helpful! Great video! Thanks
Thank you so much Marcelo! I'm glad you liked it! 😊
great tutorial, you earned a sub!
Thank you, very informative and helpful
very helpful video, thanks for your help
Hello. Unfortunately my English is not very good. Come from Germany.
But I would like to take this opportunity to compliment you on your very informative videos. And yes, I can understand most of it.
Thanks for so much Python input.
Maria, you are great! 👍
Happy birthday :* thanks for tutorials ;)
Thank you so much fnuker!! 😊😊😊
Great video. Speaking of interesting dates your birthday this year is on quite interesting day.
hahahaha I agree! plus being a Gemini whos' born on the 22nd is always a bonus! 😁
Thanks for the video! datetime objects was being a challenge for me. I wasted at least 30 minutes looking for ways to convert my dataframe's date column which were integers.
Hi Matheus 😃
If you're working with Pandas, there's a special conversion method which you might find useful, try:
my_df["date"] = pd.to_datetime(my_df["date"])
It might be a quicker 😉
And thank you so much for your lovely comment! 😊
Funny I was watching this (almost) on your birthday! Happy birthday!
Thank you so much Christopher!! 😀😀😀
please 🥺 complete python tutorial for absolute beginners 🥰your talking way is easy and understandable
one part please 🥺
9:04 - 9:09: For people who like it precise. An if condition helps out :)
Ur soo active and genius
Great videos keep it up! :)
I am binging on these tutorials😊
Really Nice!! How would you accomplish the task of rounding time to the next 15mins?
Great content🤓 THX
Yeeeey!! Thank you so much, I'm glad you liked it! 😁
I like it because you are going on persistent 😎 also you mentioned Nicola Tesla, I liked that very much. Did you know his birthday without looking🤓?
hahaha nope! I must admit that I've googled this one! 😉
However the Chernobyl disaster date - I remember it since 12th grade! I've done a report on it for English class and it's in my brain ever since... God knows why 🤷♀️ hahaha
Thank you very much for this excellent video! I was searching for the solution of my problem and I found the clues here. My point was to print out the current date and time only with hour, minutes and seconds. And I did it like this:
now = datetime.now()
current_time = now.strftime("On %A, %d of %B, %Y at %X")
print(current_time)
-> On Tuesday, 24 of May, 2022 at 18:54:20
You are awesome!!
C est fantastic.
Merci beaucoup, mon ami! 😀
one of the bests, thanks
and I have a question, what if we want to prompt the user for time or date?
I really have a tough time struggling with the errors. :(
The subject of time seems so trivial because we are supposed to be familiar with it; after all, we all use time daily, right? This explains why when dealing with a subject that involves time, the coding complication it brings seems a little too much to do for "something so simple". But the truth is, it is a pretty complex subject. If you don't spend the time to study it, it will always be a problem. Thank you very much for taking time to put this together.
Excellent.
8:05: and beeauuuutiful 😄❤❤❤
awesome! could you make a video talking about time series? thanks!
awesome!
I started learning Python because it is a readily available tool to interact with date/time based data. Going from zero knowledge of programming, to trying to deal with "milliseconds since 1 Jan 1900" date/time, and associated data was challenging, but satisfying to solve. I wish this video had been around a couple of years ago, but I still learned a few cool things from it too.
Mariya, can you please send this back in time? ("import time_machine as tm" doesn't work in my version of Python)
I would try a different import statement: "from quantum_realm import time_travel, x_particles, lucky_underware" 🤣🤣🤣 hahahahaha
I'm super glad you liked the video! and you're right - I should have filmed it a while back, it's quite a basic topic but also easy to miss! 😉
I find that many folks are using strings instead of date objects without even suspecting there's a special data type for them!
@@PythonSimplified If i succeed in getting quantum_realm imported, I'll be sure to post some new comments 6 months ago.
@@cerealport2726 🤣🤣🤣🤣🤣
(please include the winning lottery numbers when you do so! 🤣🤣🤣)
this is what i need thank you ....i have hard time :)
chernobyl you really think is a good time to talk about it :)
Yeyy! Super happy you found it useful! 😁
Everybody talks so much about Ukraine in recent days - feels like if I don't include it in a video - nobody is going to watch it 🙃
It's actually one of those dates that you remember for years (specially the time!! 01:23:4 is absolutely insane!!) I've done a report on Chernobyl when I was in 12th grade and it's still in my memory since then! 🤪
The other memorable date I had in mind was September 1st 1939... but it might not be the best time to talk about WW2 either 😅😅
Great video
Thank you so much Rashid! 😁
Thanks!
You're absolutely welcome! have fun! 😀
thanks A LOT TEACHER GOS BLESS YOU Awesonne from SENEGAL
I'm first🔥❤️🇳🇵
Thumbs UP☝👍👍
Thank you so much Alphabet! 😀
Where did you get the third thumb?? 🤪 hahahahaha
can you also make a video on how to implement timer in py . If you know any source then pls share it as my project requires a timer logic where I start timer of 10mins and if time is elapsed , I call a function but if not then I reset timer . any idea how can this be implemented?
thanks a bunch for making python tutorials like these :D
I think if you make a playlist, it will be amazing to solve the questions of the Rank Hacker site
Hi Pouya! 😀
I generally try to stay away from things that include the word "hacker" in them 😅
I'm already known for my bot-making tutorials (which probably ended up terrorizing some of my cyber security collogues, and actually some of the techniques I've shared ended up being used against me by Instagram imposters and DoS folks hahahaha 🤣🤣🤣 which is ironic... but totally deserved!! I can't really complain about it 🤪)
So even if I get involved only in simple white-hat stuff and share it on this channel, eventually it will be used against me! But I wish I could! it's a super interesting topic! 😊
By the way, the name of one of my best friends in Canada is also Pooya! (he just spells it a bit differently 😉)
hi 🖐🏻
thankyou for reply
I think making videos about solving Python questions can be useful for programmers.
You are right about my name, both modes of writing are correct.⚘⚘
respect☺☺
Hey Hey, Just a question about the use of {} placeholders rather than using print(f"it's the {now.minute}th minute of the {now.hour}......") Is there a reason why you use place holders rather than putting the variable directly in the curly braces?
I should have read the comments....
Can u do a tutorial on kivy date picker Widget and also an example project on that?
I'm currently working on an activity that takes date input from user and wait for that particular time (then do some task like: reminder, showing a toast message etc.). I've used DatepickerDialog in Android studio, but I wanna know how it could be implemented in kivy
Thank you so much for suggesting! 😀
I'll definitely look into it! I have a few upcoming GUI projects (Pygame, DearPyGUI redo and Tkinter redo), I might be able to cover another Kivy app as well! 😉
BTW KivyMD has some really nice date and time pickers: kivymd.readthedocs.io/en/0.104.1/components/pickers/index.html
You might like them more than their Kivy equivalents... I actually always prefer KivyMD, especially when it comes to mobile apps! 😊
Thanks for all your videos. Very well done.
You have a very cute accent and I hate to mess with it, but I feel like I should maybe helpfully point out that when we use the verb “attribute” in English, it rhymes with “contribute” and “tribute”, just like you say it. But when we use the noun “attribute” I almost always hear the emphasis on the “at”. So “ATtribute”. Crazy, maybe. Or maybe to help distinguish the noun from the verb. Who knows. Not sure if you want to reduce your accent or not. It is a cute accent.
Anyway. Thanks for the vids.
Thank you so much Joel! 😀
Are you sure it's not a British pronunciation? I'm yet to hear “ATtribute” here in North America, but my British lecturers from UoL use it all the time! 😊
Also, I don't know if accent is something you choose to have... 😅 or else you're an actor or something! hahaha
It's just how your mouth reacts when your brain commands it to things, if you could control it - we'd all speak like Morgan Freeman! 🤣🤣🤣
@Oversight so noun versus verb kind of situation, eh? KK guys, I'll try it the other way around next time I say attribute! 😉
Please can u recommend a book to study for basic python
Doesn't the time difference come from the implementation needing to call the function twice for each instance? Because you're essentially calling the function 2^(idx-1) times for the Fibonacci problem, as opposed to what happens with the loop on the first problem
Good Morn'ng!
Good Morning! 😀
Please make video on tensorflow directml
I had difficulty converting integer timestamp into readable time, I finally used pandas to do the conversion for me.
Happy late Birthday! 😁
Happy Belated Birthday :)
14:44 I was muttering the same date just before you said it while watching "2022, 5, 2..." how could this be? :) Anyway, thanks for this great video, very useful.
hahahaha great minds think alike? 😉

Thank you so much for requesting Davood! 😀
I'll film something about abstract OOP classes soon, while MongoDB will take a bit of time but it's definitely on my list 😉
Maria can you do the next lesson about apscheduler?
Hi Shahobiddin! 😀
I just checked out their documentation and I believe there's a better solution for this... are you looking to schedule certain events in your app? like a calendar that sends you reminders? or did you have another functionality in mind? 😁

can we do python programming and app development in mobile ☹️I don't have laptop
Write a python function to get well formatted date. Input date format to the function is "DD/MM/YYYY" and the output format must be "DD Month YYYY".
Eg. If "15/05/1995" is the input to the function then it must return "15 May 1995" string.
You must use following MONTH list in your code.
MONTH = [None, 'Jan', 'Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec']
Test Cases (INPUT=>OUTPUT)
1. '01/01/2001' => '01 Jan 2001'
2. '20/5/2010' => '20 May 2010'
3. '9/9/2021' => '9 Sep 2021'
How can you work out the age of a person from their original birthdate to the current date now? So for example, 33 years, 54 days old.....
Can you make a tutorial on how to use python to scrape mobile applications?
Usually mobile applications have a desktop equivalent and they're really easy to target! 😊
For example - instead of accessing Instagram through the phone, navigate to instagram.com on your computer and then you can scrape it with no problem with Selenium! Same goes for other social media platforms like Facebook, LinkedIn, Twitter, etc.
I have a bunch of tutorials with Selenium scraping social media, it's the go-to tool when you don't want to be detected as a bot! 😉
⭐ web scraping entire Facebook image gallery with Selenium:
ruclips.net/video/SsXcyoevkV0/видео.html
⭐ web scraping Instagram images with Selenium:
ruclips.net/video/iJGvYBH9mcY/видео.html
⭐ automating LinkedIn contacts using Selenium:
ruclips.net/video/7aIb6iQZkDw/видео.html
In terms of scraping the actual mobile app - you may run into issues as you won't be dealing with DOM elements (which you see in web applications) but you'll be dealing with GUI widgets which are much more complex to target if you're not familiar with the source code.
You can easily find the source code of web applications through the "developer tools", but in terms of mobile apps - it's a completely different ball game! 🙃

Madam please and please help me. I developed E-learning management systems where I want the admin sqlite3 database (user_loader(UserMixin) should be different from the students own how do I go about it.

Hello, you Can you help my idea of "date" put into to database of SQLite. Eg likes Birthday or Date of Birth. My idea is can you do "Qt designer" is "QtDateEdit" of the object is "dateEdit"
I am trying to work out the python programming for input into the database. You to you.
Hi Andre 😀
SQL actually has a special data type for dates and you can insert and select them from a table quite conveniently.
You can find more info in this W3 Schools tutorial: www.w3schools.com/sql/sql_dates.asp
I'll be covering SQL in much more detail in an upcoming tutorial, but I don't want you to wait for so long! 😉
Good luck with your project and I hope it helps! 😊
great video as a beginner I learned a lot today, but it's hard to concentrate on the code, she is very beautiful.
