Python Programming


What is Python Programming?


Programming is an act of giving instructions to computers for processing and publishing information. There are multiple languages to do this task. But an easy and powerful language is what the world is looking forward to.


Python programming language is just the right choice, with a very easy English-like syntax and computing abilities in multiple different fields like testing automation, network scripting, devops, data analytics and machine learning, web application, GIS etc.


The author of Python programming is Guido van Rossum. First version of Python 0.9.0 was released in February 1991. Since the beginning, python programming language has featured object-oriented, interactive, and interpreted coding styles. The emphasis was always on clean and readable code without sacrificing performance. Python is also a portable and open-source language with a very supportive and active community base. This is the reason why building software in python is fun for everyone including beginners. Dropbox, BitTorrent, Quora, Instagram, Cinema 4D are some of the popular applications in python.


The Zen of Python of its guiding principles can be seen in the python shell with the below command:

>>> import this


Art of Programming


Programming also revolves around data collection, data processing and data publishing. The sources for data input and output may vary from console to file to database to web to socket. But the art of programming always involves writing the routines for these simple steps.




Program Recipe in Python


Although a software program is subject to the business case for which it is written, some steps are always in the program structure. A meaning knowhow of these steps will help you write any program in Python. You may approach a problem statement in below steps:


Step 1: Take the given input

Step 2: Assume the output as per the program input-output data type format

Step 3: Use loop for iteration

Step 4: User condition for filtering, as required

Step 5: Process the input data with operators, functions or methods.

Step 6: Publish the program output
