Python Basics

Python Tutorial For Beginners | Learn Python

Programming from Scratch

Python is a general-purpose programming language which can be used for almost anything
may it be to develop web pages or for machine learning or any sort of simple application Python
has you covered so you would wonder where did it all start in the 1980s
...
Python is an open source language which means that it is free
for anybody to use
...
Python also supports oops meaning that
you can model a real-world problem into your code and you can have security for it
...
The National Security Agency uses Python for cybersecurity analysis and also for
encryption and decryption purposes
...
Netflix uses machine learning to cluster certain groups of its users and recommend
TV shows to detain them
...

you can download either the professional version or the community version for the purpose of
the tutorial I will be downloading the community
...
to download the professional
...
PyCharm python v6 open so as you can see I
have all the different topics that we will be covering the data types file handling flow control
functions operators all of this so let me just come out of the presentation mode now let us move
ahead with the next part of our tutorial so I hope all of you are clear with this
...
The other thing that you
have to remember are that numeric data types are not mutable
...

Type conversions are basically used to convert a data type from one form to another so let
me go ahead and show you some of the more functions that are available to you which you can
use for type conversions
...
explicit type conversion is done by faith in
itself so it converts the a which is an integer into a floating number
...
type conversions
can be used to convert data into an integer or an octagonal number
...
Lists are the same as arrays with one exception that they can have different
data items inside them arrays would only have a particular data item within them
...
indexes are basically the
address in which the data is stored in Python
...
If I want to access a particular
element I have to pass the index value of it so if I have the element 2 it is stored at the index 1
so the address always starts with 0 up till how many ever numbers you have
...
I skip ed Eureka and I print Python so that is how
you have obtained the output next is the third element and the second next the next is I can also
access particular elements within the elements
...
If I am printing all of this it does not change the actual data
...
