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:
And by using the module fibo, you can access the functions that you had already created for your program using the Python script.
