Great video for beginners. Should make a video on specific libraries that are handy for specific data types aimed for more intermediate users too (e.g., built-in 'slice', or 'insort' from bisect for list types, 'nested_lookup' from nested_lookup for dictionaries)
I got [999, 8]. I had to guess what the isinstance function did in the end. Assuming it filters out anything that isn't and integer, otherwise it would be [999, 8, 'a',' 'b', 'c'] (I think). Great video.
Great content Tim! Thank you for your effort in creating this type of content for us! It's a good reference video to refresh the knowledge on the lists.
Do you have a video about how to find out if the checkbox is checked or not using Flask? (The IDs and the Values are dynamic from the database) Thank you
Okay here is my attempt! n1 is list a of even numbers, n2 is a list of odd numbers. on line 4, you are making a list of those even and odd numbers as zipped. on line 6, you are collecting the numbers from this list starting from index 0 and going backwards by -1 step. Reversed order? on line 8, you are the odd numbers in reversed order to the end of the zipped_2 list on line 10, you are replacing a number with 999 at position -5 on line 12, you are replacing three numbers with a, b, c from position 1, 2, 3 on line 14, you are sorting the n1 list in reverse order if they are a number they will be sorted first. finally printing the results
@TechWithTim ......Hello Tim!...Thanks for video you've made i appreciate so much.......Does the Coursecareer programme apply to every country......I am a Nigerian in Africa and all i can here is North America related settings
Thank you so much, even when one becomes very well versed in programming, there are always a few tiny things that one can miss out that may hinder performance and usefulness of a langauge.
Thank you very much for this. Knowing that setting a list equal to another is by reference allows me to link my understanding of C pointers to Python now. This had confused me for quite some time.
hey Tim, thanks for you all videos you are so inspiring for me im learning django online, but i get tired of it so soon, its like a loop for me getting tired, break, starting again, getting tired its not enjoyable for me but i have to learn it please give me advice , what can i do to finish my course
Thank you! Waiting for more such content. How about "Sorting lists"? For LIST construction: one can use unpacking like this: >>> lst = [*range(11)] And for immutability of tuples - it is a disputable theme. Say we have a tuple: >>> tpl = 1, 2, 3 >>> tpl += 4, >>> print(tpl) # (1, 2, 3, 4) # Yeap, id(tpl) in these cases will be different. These are different objects. But by construction looks like we can modify tuples )). Another example: >>> tpl_lst = 1, 2, 3, [4, 5] # check for it's id -- id(tpl_lst) >>> tpl_lst[3].append(6) >>> print(tpl_lst) # check for it's id again # (1, 2, 3, [4, 5, 6]) # and in this case ids of tpl_lst will be the same. It will be the same object to your computer.
I don't think it is disputable, tuples are still immutable. Using the += operator just creates a totally new object in the background. I admit the second is strange indeed, the answer is that mutable object stored/pass by reference in Python. (You can use copy() and deepcopy() to break that reference if you need to.)
Hello Tim!....Does the Coursecareer programme apply to every country......I am a Nigerian in Africa and all i can here is North America related settings
Bro, I love your videos a lot, you teach everything well, I wish I was in the position to buy your course, but am financially disadvantages now, however, in the mean time, is there any chance you could share the link to your iconic soundtrack that plays at the end of the video? It really helps me focus more when am practicing code, am a beginner in software engineering, and am learning things off of youtube videos like yours, and progressing one step at a time.
Hi, i didnt get what the problem is with the list being a default parameter. i am very new to pyhton and coding in general. did i get it right that, if you change the list in the function, that everytime you call the function, it executes the change because... well its in the function so it does what its supposed to do, right?
This was great but you did not cover lambda functions showed in the first slide! As a total beginner with python for research needs those lambda functions are much less transparent than other things. Thanks for list comprehension though, very effective brief explanation!
Constructive criticism - please don't use "LST" (lowercase) as a variable for a list. 1. "lst" in monospace looks like "1st" - the lowercase L looks like a 1. 2. Try to avoid using variables that are so close to a keyword. 3. Tell your audience not to use keywords as a variable, or else Python go boom. Thanks, Tim! Always love your content.
And to provide a solution, try to use something like "my_list1" and "my_list2". Semantically it infers that the variable is defined and owned by "you" in the memory space.
Hey bro. Can you please pronounce what your type in the screen? I mean when you do the parentheses or quotes? I am visually disabled and I’m trying to keep up with you, but I get lost. Thank you very much.👍🏾
Is there any way to force a data type when we declare a collection in Python? i.e. if I declare a list, I have to tell what data type that the list elements are of.
Yes, you can do so using the array module from the standard library. Although arrays can only store numeric values and characters, so they aren't the exact same.
Am a little late, but when assigning values using slice notation they have to be an iterable, hence the brackets around the 999. If you don't have the brackets it'll throw you a TypeError. Since it is using the slice -5:-5, you are assigning to the -5th index. Since it is only one index, you can just do the same operation as lst[-5] = 999 (lst[0] = 999 also works since index 0 is the same as -5 for this example)
What color scheme are you using in VScode? I love the high contrast stuff, and these color combos look better than my current. Thanks for the video too. I learned quite a bit!
.snap() break list in half, return halves in a tuple .crackle() remove every other item, return new list of those items .pop() remove last item and return
def func(lst = [1,2]): lst.append(100) return lst lst1 = func() print (lst1) lst2 = func() print (lst2) lst3 = func() print (lst3) Result: [1, 2, 100] [1, 2, 100, 100] [1, 2, 100, 100, 100] [Finished in 0.2s] This is my result. But how you got like the following. May be I am wrong. [1, 2, 100, 100, 100] [1, 2, 100, 100, 100] [1, 2, 100, 100, 100] Correct me if i am wrong

Og here , Idk what has happen to your channel, Now there is definitely decrease in engagement . You should try going back to old ways . I used to watch your channel for Discord bot and flask app and what not . Try Making a series on some trending thing again . Like I would love a series where you make a evolution simulator or a journal app which after 20-30 days writes a AI generated book on you and what your wrote in journal .You get the gist . Make a series , it will keep the engagement and we get old tim back :)
I would say his new series is the “ Introduction to Software Development “ as it’s a perfect way for anyone new like myself to enroll in the possibility of getting a job at the end. He’s got plenty of old content for anyone new to go back & watch. He did mention his latest & greatest work was the course he created. Which lets me know he put endless hours into creating it. The newest releases on his channel are amazing in my opinion when you factor in how much work goes into making RUclips videos along with having a day job & other side projects. Just my two cents LoL I’ve only been around for two months but I can tell you that building up a RUclips channel this large is not easy. The fact he has been able to teach so many this one language but do it a millions times in a millions different ways is beyond impressive.
8:00 Does this ever serve a purpose ? It looks like a useless feature. If i already have a reference to an object i don't see any case where i will need a different name to call that same reference ever. It looks more annoying than useful.
Imagine that you need to remove elements from different lists, such as employee and student lists. Each list contains multiple elements represented as dictionaries, either for students or employees. When you want to delete an employee, you might consider creating a method like 'remove_employee(id)' that searches for the specific employee and removes it from the employee list instance. Similarly, for removing a student, you would need to create another function, 'remove_student(id),' which follows the same approach. However, this approach is not ideal. Instead, you can streamline the process by using a single function that accepts the list instance and the ID as parameters. Let's call this function 'remove(lst, id).' Now, when you want to delete an employee, simply call 'remove' with the employee list and the employee's ID. You can do the same for students or any other entity with the same data structure, ensuring a more efficient and maintainable solution.
Thank you a lot. :) @@eddo4life I will have to test this out myself in order to fully understand how it works, but i think i vaguely get the idea already. :)

Thank you very much for this. Knowing that setting a list equal to another is by reference allows me to link my understanding of C pointers to Python now. This had confused me for quite some time.
One thing that all these tutorials lack is the fact that a LIST in Python is equivalent to an ARRAY in most other coding languages.
Great video Tim! Please do the same for other data structures.
