Python Tutorial

Python Tutorial

Python is widely used, popular, high level, interpreted general-purpose programming language. Guido van Rossum initially designed python programming language and later it was developed by Python Software Foundation. The main motive for designing and developing python is easier code readability and allowing programmers to express concept, design, and logic in very few lines of code design with the help of white spaces during coding. Due to simplicity and better code readability, it is very easy to learn python to anyone who is new to any programming language. This tutorial gives a basic understanding of the python programming language.

Why do we need to learn Python?

• Python can be used with different platforms like Windows, Linux, Mac, Rasberry pi, etc.
• The syntax of python is very much simple like English syntax with the use of white spaces during coding. Because of this, expressing logic using python is very easy and simple.
• Python allows programmers to write code in a procedural way, functional way and also an object-oriented way.
• Due to code simplicity, many open source libraries used now a day in machine learning, data science, and other complex mathematics functionality are also very easily available in python.
• Python relies on indentation to define the scope of loops and condition which makes it easy to code during coding.
• Python can be run on an interpreter which allows programmers to run it quickly as soon as code is written. Due to this programmers can check their logic very easily during coding.

 Applications of Python

• Python is available under a free license which makes python free to download and free to use for all research and commercial application.
• Python can be used to create a Desktop GUI applications.
• Python can be used to develop web-based applications. It provides a library to handle internet protocols and to develop web-based applications.
• Python can be used to connect to the database and modify the database.
• Python can be used in big data, image processing, machine learning, and other complex mathematics function, etc. with many open-source libraries available.
• Python can be used as script development to perform automated software testing.
• Python is mainly used for prototyping software development because it’s easy to use and easy to read features of code.

Example: (One short example)

To have an initial understanding of python programming language, have a look at the below sample example code where two age variables are taken as input and compared those for age comparison.

Example Code:

age1 = 100
age2 = 80
if age1 > age2:
print("age1 is greater than age 2")
else:
print("age2 is greater than age 1")

Example Code Output:

Pre-requisites

You should have a basic understanding of programming language methodologies like variable, condition, looping, constants, operators, etc. Knowledge of any other programming language is an added advantage to learn this tutorial.

Target Audience

This tutorial is designed for those software programmers who wish to understand about python programming language and wish to apply python programming in their project.
