Introduction to Python

INTRODUCTION 

Python is widely used general purpose, high level programming language. Developed by Guido van Rossum in 1991. It is used for software development, web development (server-side), system scripting, mathematics. 

Features of Python 

1. Easy to use – Due to simple syntax rule 

2. Interpreted language – Code execution & interpretation line by line 

3. Cross-platform language – It can run on windows, linux,   etc.                equally 

4. Expressive language – Less code to be written as it itself express the purpose        of the code. 

5. Completeness – Support wide rage of library 

6. Free & Open Source – Can be downloaded freely and source code can be modify for improvement Shortcomings of Python 

1. Lesser libraries – as compared to other programming languages like C++, Java, .Net 

2. Slow language – as it is interpreted languages, it executes the program slowly. 

3. Weak on Type-binding – It not pin point on use of a single variable for different data type.

 

Input and Output   

variable1=‘Python Programming' 

variable2=‘Java Programming ' 

print(variable1,' and ',variable2,' ) 

Output :Python Programming and Java Programming 

raw_input() function in Python allows a user to give input to a program from a keyboard but in the form of string.
