INTRODUCTION TO PYTHON
Python is a widely used general-purpose, high level 
programming language that is often applied in Scripting 
roles.
It was created by Guido van Rossum in 1991 and further 
developed by the Python Software Foundation. 
Python is a Programming language as well as Scripting 
Language
It is also called as interpreted language.
PROGRAMMING LANGUAGE VS 
SCRIPTING LANGUAGE
Programming Scripting
• A program is executed that • A Script interpreted
is the source is first • A “script” is code written in 
compiled and the result of a scripting language is 
thar compilation is expected nothing but a type of 
• A program in general is a programming language in 
sequence of instruction which we can write a code to 
written so that a computer control another software application 
can perform certain task
WHY DO PEOPLE USE PYTHON?
Python is object-oriented
Structure supports such concepts as polymorphism, operation 
overloading and multiple inheritance.
Indentation
Indentation is one of the greatest future in Python.
It’s Free(open source)
Downloading and installing Python is free and easy Source code 
is easily accessible
• It’s powerful
Dynamic typing
Libraries utilities
Third party utilities(e.g. Numeric, NumPy, SciPy)
Automatic memory management
• It’s portable
Python runs virtually every major platform used today
As long as you have a compatible Python interpreter installed
Python programs will run in exactly the same manner 
irrespective of platform
It’s easy to use
No intermediate compile and link steps as in C/C++
Python programs are compiled automatically to an 
intermediate form called bytecode, which the 
interpreter reads
This gives Python the development speed of an 
interpreter without the performance loss inherent in 
purely interpreted languages
It’s easy to learn
Structure and Syntax are pretty intuitive and easy to grasp
