This document provides an introduction to the Python programming language. It discusses that Python is a popular general-purpose programming language created by Guido van Rossum in 1980. It is commonly used for web development, artificial intelligence, and software development. The document outlines how to set up a Python environment, including using an integrated development environment (IDE). It also introduces key Python concepts like variables, data types, arithmetic operations, user input, comments, conditions, loops, and functions.

2. CONTENT OF THIS COURSE
 Here’s what you’ll find in this Course :
 Introduction to python general-purpose programming language.
 What Python Used for.
 Companies uses Python.
 Setting Up the Environment.
 Start Python Programming

3. What Python is?
Python is a popular general-purpose programming language.
It was created by Guido van Rossum in 1980, and released in 1991.
It is used for:
 Web development (server-side).
 Artificial Intelligence .
 Software Development.

8. Top Companies using python

9. What make it so powerful for that is because it
has a many framework!

A framework is a set structure in which tasks are performed or
completed. Typically, a framework refers to an often layered structure
that indicates what kind of programs can or should be built and how they
would connect to each other.

10. Setting up the Enviroment

11. An integrated development environment (IDE)

12. Why it’s better to use an IDE than Running
code in Note pad with python Compiler

13. Functions

14. WHAT DOES A COMPUTER DO?
 performs calculations a billion calculations per second! two
operations in same time light travels 1 foot.
 Remembers results
 100s of gigabytes of storage!
 typical machine could hold 1.5M books of standard size

“Talk is cheap.
Show me the code.”

16. 01:Variables

17. Variables
You can think of variable as a little box or a container to store data in the
memory of the computer and later retrieve the data using the variable “name”
Programmers get to choose the names of the variables
You can change the contents of a variable in a later statement

20. 03:User Input
Python has an input function which lets you ask a user for some text input.

21. 04:Comments in Python
Comments in Python begin with a hash mark ( # ) and whitespace
character and continue to the end of the line. Because comments do not
execute, when you run a program you will not see any indication of
the comment there. Comments are in the source code for humans to read,
not for computers to execute.

22. 05:Conditions
Python uses boolean logic to evaluate conditions. The boolean values True
and False are returned when an expression is compared or evaluated.

25. 06:Loop
Python has two primitive loop commands:
 while loops
 for loops

26. 07:Data Structures
Every child knows that one can – at least beyond a certain number
– find things much easier if one keeps order. We humans
understand by keeping things in order that we separate the things
that we possess into categories and assign fixed locations to these
categories that we can remember.
We may simply throw socks into a drawer, but for other things like
DVDs it is best to sort them beyond a certain number so that we
can quickly find every DVD.

29. 07:Data Structures
There are four collection data types in the Python
programming language:
List is a collection which is ordered and changeable. Allows
duplicate members.
Tuple is a collection which is ordered and unchangeable. Allows
duplicate members.
Set is a collection which is unordered and unindexed. No
duplicate members.
Dictionary is a collection which is ordered* and changeable. No
duplicate members.

07:Data Structures-List
 Lists are used to store multiple items in a single variable.
 Lists are one of 4 built-in data types in Python used to store
collections of data, the other 3 are Tuple, Set, and Dictionary,
all with different qualities and usage.
 The list is changeable, meaning that we can change, add, and
remove items in a list after it has been created.
 Lists are created using square brackets:

31. 08:Functions

32. 08:Functions
A function is a block of code which only runs when it is called.
You can pass data, known as parameters, into a function.
A function can return data as a result.
