Introduction to Python
❖Python is a widely used general-purpose, high-level, interpreted, interactive,
object oriented and reliable programming language.
❖It was created by Guido van Rossum, and released in 1991.
❖Python got its name from a BBC comedy series from seventies- “Monty Python’s
Flying Circus”.
❖Python has a simple syntax similar to the English language.
❖Python works on different platforms (Windows, Mac, Linux, Raspberry Pi, etc).
❖It has vast library of modules to support integration of complex solutions from pre
built components.
Features of Python
a) General purpose language
❖It can be used to write code for any task.
❖Nowadays, it is used in Google, NASA, and New York stock exchange.
b) Easy-to-Learn
❖A Python program is clearly defined and easily readable.
❖The structure of the program is very simple.
❖It uses few keywords and clearly defined syntax.
❖This makes it easy for just anyone to pick up the language quickly.
c) High-level language
❖When writing programs in python, the programmers don’t have to worry about the
low-level details like memory used by the program, etc.
❖They just need to concentrate on solutions of the current problem at hand.
