Python Improved Logic to Calculate Factorial

I am practicing Python programming. In this post, I have explained logic to calculate the factorial using a function. This function you can call it a user-defined function. The name of the function is

In real-time, you can write a program in a file and run it in python console. The main task of a developer is to create functions for the reusable code. They call these functions whenever they need.
Factorial calculation program for supplied input value.
 Python logic easy way to calculate factorial using user defined function. Useful for your project.

Factorial Logic in Python. I have completed this logic in 3 steps.

  1. Write
  2. Import
  3. Execute it


Here you need to define a function. Use 2 for loops, and write your logic. This is done on LInux operating system. You can also try on Linux.
After, ESC command
Use, :wq to come out of the module.


Go to Python console, using 'python' command. Use import command.

import function


>>> factorial.fact(5)
It will show the result of factorial.
factorial result

Bottom line

 Factorial of 5 = 1x2x3x4x5= 120
