2.2 PYTHON—PROGRAMMING LANGUAGE

2.2.1 Python Introduction

In the previous section of this chapter, we learnt about the tools and techniques used
to develop the structure of a program. These tools, like flowcharts and algorithms, are

essential to draw a layout of the solution to the problem. Once the process of designing is
completed, now it’s time to convert the structural design into programmatic code that a
computer can understand easily. This process is known as coding.

Coding can be done in any programming language. We will use Python as a programming
language to write code.

Python: Python is an open-source, high-level programming language which has a simple
syntax similar to the English language. Python was created by Guido van Rossum, and first
released on February 20, 1991. The language name is not about snakes, but was inspired by
the British Comedy Troupe Monty Python’s Flying Circus. Guido Van Rossum is a big fan

of Monty Python’s Flying Circus. Python is used by many big companies like NASA, Google,
Nokia, IBM, Netflix, Facebook and Yahoo Maps etc.
