What is a Python Script and Python Module? – Python for Beginners

This video tutorial is for the individuals who wants to Learn Python Programming Language. It is a simple Python Tutorial for Beginners.

Whenever you exit Python interpreter and enter again, the definitions you have made (e.g. functions and variables) get lost. And by writing a program using a code editor to prepare the input for the interpreter and run it with that file as input instead. This is known as creating a script.

As your program gets longer, you may want to split it into several files for easier maintenance. Python has a way to put definitions in a file and use them in a script or in an interactive instance of the interpreter. Such a file is called a module.

A module is a file containing Python definitions and statements. The file name is the module name with the suffix.py appended. And inside a module, the module’s name (as a string) is available as the value of the global variable __name__.

Below here, we are explaining what Python script and Python Module are. We are using the example of the fibo module to perform a Fibonacci function.

The simple Python script code can be found here:

# Fibonacci numbers module 
 def fib(n): # write Fibonacci series up to n 
         a, b = 0, 1 
         while a < n: 
                 print(a, end=' ') 
                 a, b = b,  a+b 
         print()

def fib2(n): # return Fibonacci series up to n 
         result = [] 
         a, b = 0, 1 
         while a < n: 
                 result.append(a)
                 a, b = b, a+b 
         return result

Now enter the below Python interpreter and import the fibo module with the following command:
