How to create local variables in Python?
Let us see an example of how to create local variables in Python. Normally we declare a variable within a function to create a local variable. Python has a simple rule for local variables, if a variable is assigned to a function, then the variable will be considered as local variables and you can access the variable inside the function only.

A variable is declared in a function called a local variable. The local variable scope is limited to the function it was created for.
