#0 Python for Beginners | Programming TutorialPython is the fastest growing language which is Python. Ivan Verdi will try
to make this session as much as interesting as possible maybe with the help of
animations and different stuff. The Python series will be fun to learn and dagdu
it is freely available so you can learn the adapt by the language for free.
#1 Python Tutorial for Beginners | Introduction to Python
Python is one of the fastest-growing language in what terms in terms of
number of developers who are using it. In this video we will talk about what is
Python and why it is so useful and why you should learn it. The author of Python
he 's a big fan of a British comedy movie called as Monty Python. Python is one
of the easiest language to learn and even if you are from a non-technical
background you can start with Python. Python came into picture just to help
those people who do n't know how to read a code in fact children can learn
Python is that easy now Python has multiple versions we have one point X.
#2 Python Tutorial for Beginners | Python Installation |
PyCharm
If you want to write a code now you simply need to open an editor when
you write a cool and we can use notepad or notepad plus plus plus all Adam or
sublime does n't matter which language you're working on maybe C C C++ Java
or Python. Python 3. 7 is the latest version of the latest Python version. Python
is free so we 'll be using PyCharm here now is it free that 's the question let 's
try. We need two things one is interpreter and second is IDE which we should
be referring. You can verify that is by going to your windows of course and
saying hey I want to use Python now you can see we got a Python zero point
seven set up so that we can go with this one or you already get an IDE called
as I dl e where you can also add your code right. Click here to learn about
Python in this video.
PyCharm can be set up for some types of Python files or some extension. Do
not import the setting click on OK and it will ask you for the team. Click on
install and in some time it will get installed so you can see we got this setup
done.
, #3 Python Tutorial for Beginners | Getting Started with
Python
Python is a programming language and a binary format language. It is
the language which computer understands is binary code which zeros and ones
now it is not actually possible right of course so what you have to do is use a
language which will which both will understand and of course do we so do we.
Python is one of the easiest programming languages in the world right so what
I will do is I would say two plus three this is the simplest task you can do on
Python. When you subtract two numbers we argue that number right and
specifically this are integer numbers right we all use integers but then when
you divide a number it is giving you a point value now which is also correct
float numbers. You can have multiple operations but then we have to follow
grommet right if you say 8 plus 9 and then subtract you forgot to type 10 there
it will give you an error which is invalid syntax and that 's why you need to
follow the grammar as well.
We have to use a special symbol here which is modulus and we 'll say 3 you can
see we got 1 which is a remainder so when is a 10 more than 3 you will get a
limiter which is 1 okay this works yay now you know all the operators right now
what else we can do here? If you observe here we have single code as a starting
one and then we also have a single quote here so that means that is one string
and then this thing which is s laptop it is not as a part of that single code that
's what that that's where the problem starts so you can not simply have single
quote anywhere right so how do you solve this problem? We have two solutions
the first one is you in stop using single quote you can use double quotes
example. Problem starts so what you will do now because if I say enter you got
invalid syntax in that case we will say single quote navin's and then in double
quotes will say laptop. Problem is with this s right this s is coming before a
single quote so you have to tell your Python hey Python can you just skip that
special meeting of that single quote and the way you do that is by giving a
slash.
In this video we have only talked about how can we use certain operators and
then playing with printf in the next video we are going to talk about how to use
variables now. The next video will show how to play with variables in Python.
#4 Python Tutorial for Beginners | Variables in Python
Devin 20 talks about what is variable in Python. What is variable so
basically variable is a container where you can put your values. The term simply
means you can change the value can be changed here. In assignment what we
