In this lecture we will learn:
- How operations are performed in Python language?
- Different types of Arithmetic operations
- What are strings?
- How strings are used in Python?
- Function in a Python
- Concatenation and Repetition of Strings
- New line character and Raw string
#1
- We will the Python IDLE in this tutorial.
- The language that the computer understands is Binary Code i.e, 0 and 1.
- We use a programming language to write code, which is neither a binary language nor English.
- Programming language has its own protocols and grammar which we use.
- We will write code in a programming language say Python and then it will convert into a binary format that the computer will understand.
- We can perform several operations using Python language.
#2
- Starting with operations like Addition, Subtraction, Multiplication, and Division.
- We do addition, subtraction and multiplication with integer values, and then it gives us answers also in integer data type.
- But when performing division with integer values then it gives us an answer in float data type.
- Float stands for Floating Point Representation.
- When we divide two integer values then it might be possible that the answer can in decimal.
e.g., 5/2 = 2.5
- As the interpreter wants to give you an exact answer for the division also, it will return it in float.
- If you want to get only the quotient part or the integer part of the answer and want to neglect the decimal value, it can be done with the help of (//).
- // (double slash) is used for division when you want to return only an integer value in the answer.
- // is also called Integer Division or Floor Division.
- We can multiple operations in a single statement as well.
- We need to follow the proper syntax for the programming language.
- If we apply an operation but do not give operands, then it will give an error.
8+9- = Error
- We can also apply BODMASS rules of mathematics to perform operations.
- Double asterisks (**) is used to find the power of a number.
number ** power = 2**3 = 2*2*2
- To get the remainder, we use the modulus operator (%).
#3
- String is a combination of characters like "RUclips", "Camera", "Telusko", "Python", etc., all are strings.
- Whenever we use strings, we need to use double quotes(" ") or single quotes(' ') with it in python.
- If you back-slash(\) to tell the python to ignore the special meaning of that double and single quotes.
- If you use a back-slash before a single or double quotes then the quote is also treated as a simple character.
#4
- Function is a set of tasks that can be done. We need to call functions. There are several functions in Python like the print() function.
- Round brackets are used with a function to pass a parameter in it.
- We can define our own functions as well.
#5
- Concatenation is used to combine two things like we can convert two strings into one using concatenation.
- Concatenation is done using the (+) operator.
e.g., 'navin' + 'navin'
- Repetition is used to print a single value multiple times like we can print a string like "Navin" multiple times.
- Repetition is done using the (*) operator.
e.g., 'navin' * 3
#6
- (
) has a special meaning in Python. It is used to enter a new line.
- To print the original string or to neglect the meaning of
, we have to use a Raw String.
- Raw string is a string that returns it as it is without making any changes to it.
- We have to specify (r) before the quote to print the same string that is present inside the quotes.

Why don't you write semicolon
In the last where you taught print(‘c:\docs
avin’) it is not working on my PC and it keep on saying incomplete input please help 12:54
However, the raw string working.
Why don't you wrote print
Kindly level up the video quality
Rest everything is super awesome

Best teacher on RUclips . He is making so much efforts to teach us so we should support him.
Yaar muje bta sakte ho idle ko kaise open krna hai mere pass to hai hi nahi
yes ... he is good teaching easier learn...
Sir by using raw string we can remove any of the escape sequence in the code
@@dailyquotes1181 just watch the previous video!!
yes he is supportive۔ I like the way he teach
Literally no one can explain like you so much effort and easily understand python basics ❤️😎thank you
The 3 IDEs:
1. PyCharm
2. IDLE
3. Visual Studio
Yeah what's the 3rd one
@@arjunanparthu7719 VS Code
Schools: "give us money to learn python"
YT: "learn for free"
This internet revolution is insane
Good luck being a really good CS without school. Of course you can learn to code, but you'll be limited.
Anyways there are super good CS jobs out there. It's more an investment than anything else.
Wait your schools teach coding in your schools 😮😮😮
@bro ha u are ediot its wrong check grammar
i am 13 yrs old can i learn it??
Unlike many others who do it for money ,I really like your selfless way of teaching and putting in the most public of forum,love from our side.kudos to ur efforts, will keep encouraging work like this and people like you.
great comment and i agree a lot
in 2020 august should we still download the 3.7.0 version that is mentioned in the video or latest version is 3.8.5 that plz to my question
@@VS4AA I don't think so
There's also csdojo who does it for free and to help people , he even quit his job at Google(his salary was 100K+$) to help people on RUclips
@@VS4AA latest version will also do same work becaz I am using
Excellent, thank you Navin. I instantly feel like I can just follow along with your steps and get a good understanding of this, even coming from a non-programming background. Thanks again.
I am a teacher by profession and computer specialist. Doing my degree course in BSCIT LEearning c++, but its frustration. So i decided to take the language of Python. You are the best
Hey Navin, great job. Quarantine period is on and wanted to learn a new language. Couldn't have asked for a better virtual teacher. Thanks a ton.
Second that really!
The r'c didn't work for me and I didn't need it

This is humanity, giving free lessons and that itself is just... wooowwww....thanks sir. ❤️🙏
yes this is amazing of him to do this for free, however he will be payed by RUclips per 1000 views he gets this video will have made well over £100
@Dake Lester yeah i know but, I’m saying he gets payed that’s my point
@@jeucas1274 means how much in inddian currency
bro see he told for free but he get lots of money from youtube this is how it works btw i am 12 years
I have been searching for the perfect Python course in NPTEL and SWAYAM, but none seemed simpler. I am from a non-technical background, and finding your series was the best thing that has happened to me rn.
Thanks sir for helping me❤
You're teaching style is best for everyone. New one can easily understand what you say. I like you're teaching style. Thanks a lot sir for making this PYTHON series.
Excellent interface.... 😊😊😊😊😊 like you are teaching us in front of us better than voice over... Because your presence make wonders thank you so much sirrrrrr..... Programing made fun🙏🙏🙏
Agreed.. That makes it interesting
Great video for beginners👍👍👍
I have gone through many channels and many teachers online as well as offline they were too good.
The only difference is u make us understand in a structured way which is very important . Thanks for being on RUclips otherwise ur talent and our time would have wasted .

@@dishantkumbhar8822 oh so am I starting early?? cause I am in 9th only. But by looking at whitehat jr ads, I think that I am late. Is it right time to learn it??
@@parvsheth5078 yes if u start early u can catchup with world competition easily.
There is age defined for learning .
U can learn anything ,anywhere at any age
Imp. Is u learn something new . That's it
@@dishantkumbhar8822 thanks 😀
This is what I've been looking for, and I have tried maybe 10 different high profile Python tutorials. They are mostly all good, but this one takes the same approach as an in-depth textbook which is absolutely perfect for me. I simply learn much better from videos than textbooks even though I know they contain more information so I am so grateful to be able to access this for free. Thanks!
I have really enjoyed, thank you so much ❤️
those who are learning in quarantine period like it

yep
revising python
print('C:\docs\
avin') also works in the last of the video.
For me print ('C:\docs
avin') also works
But in that case one slash will also come which may not be want
@@RK-bz9ps no it will just cancel out the special meaning of second back-slash, so it will be printed in one line with one back-slash👍
I think \\ is useful to get the integer output...with all humility but there's no point of using double slash in strings

Thank you so much for this series you made. Keep it up!
completed this video lec, and enjoying already......
Nobody has ever explained a programming language in such an easy and interesting way. Phobia has gone now.
Thank you sir!
Yep nice video, ty for taking the time to make it.
Perfect explanation.. thank you sir👍
Hi sir Im a beginner of python I need to be master in python. I enjoy python classes with your teachings. I appreciate it. I loved it. 😊😊
Hi there, how is it going for you?
>>> print('c:\docs
navin')
c:\docs
navin
>>>
That's called presence of mind but sometimes you'll get confused
@@rockingdrumzzz7887 I differ.. It's cool. But it isn't printed in same line. But still great.
You use /n before navin so it takes to u in next line the outcome will be c:/docs
Navin
>>> print('c:\docs\
avin')
c:\docs
avin
Great idea
print('c:\docs\
avin')
Also works sir
It works brother but it occurs confusion while reading

How to remove this (')?

That's very great of u 👍
PyCharm, Thonny, sublime, idle, atom, Vim are some of the famous Python IDE
what about vs code it supports all the languages
And I am here using spyder from anaconda
Visual Studio Code?
VS code is the best
Went through alot of sites to learn python and I would like to say THIS IS THE BEST
Thanku alot .Stay safe.
I am enjoying while studying ☺️☺️☺️☺️☺️ thanks for that sir
I'm really enjoying it as beginners
Thanks Navin
I am watching courses around for python and even enrolled to edx courses but sir navin is something extraordinary, the way he is presenting is really interesting, engaging and in such brief, other places it is more like robotic

Fun and playful.... First time enjoyed with coding 😂😂
your tuitorial are so easy to understand thank u Navin sir
it's so easy to understand your video. I love it. Thank you so much sir
You are amazing. Really I'm learning Python with full fun, Big salute to you
Hi! Just wanted to say thank you for teaching python. Anyways so,
print ("navin's a good python teacher")
>>>navin's a good python teacher :)
how about print('navin\'s a good python teacher')
>>> navin's a good python teacher
Thank you very much. You are a genius.
just discovered this channel, amazing content
Sir the way you taught is amazing... Everything in my mind got clear..
Amazing lectures!! Just loved the way you interact and it just feels like sitting in an actual class.
This was pretty dope, learned something new with the r for raw string part
This is an actual beginners course, starting from the very beginning. Thank you so much for this, Navin! In other 'beginner' courses I have found there is still assumed knowledge or understanding which an actual beginner can not have. I had questions immediately after watching other tutorials and I can see here these questions are being answered straight away and I already feel like I understand so much more after 3 short videos of this course.
Great Teaching..... Congratulations Sir
very nice videos for beginners
thanxs you so much
I have never seen computing language so simply taught. Looking forward to complete the tutorial. Thank you so much for helping us!! :-)
Its just an amazing for non coding background person as well💥❤
the details of his teaching are excellent
I am a student of class 6th and I have a craze to learn programming and at first I chosen Python i didn't find a correct teacher so I thought to surf on youtube and then I got your channel Telusko and then i started to learn from your videos, make notes of whatever you used to tell and this is the journey till now video#3
Thank You for considering my feedback to post Videos in 1080p.
Love the way you present a concept.
I really appreciate your work. You are doing well. Keep doing like this.
I watched many python course in yt but their techniques are not as easy and understable as your for beginners. Thanks sir for making this python series ❣️
This is classic and enjoyable. Much appreciated from Zambia
Damn better than udmey paid videos totally worth watching thank you
I agree ! I'm using zero to hero course ! What course do you use ?
Sanjay S same bro
Thank you for making learning Python feel so achievable.
You explain this way better than my lecturer (first year programming student)
first time I have got interest in these kind of stuffs , never expected as a Mechanical engineer I will have learn this, and u teach in so simple and awesome way
Really sir two different things that makes the learning more effective includes your presence on screen and the interactive layout. ENJoying a lot
I Promise you, If I learn python from you , I will pray for your hair growth😉😇🥰
