Global keyword is a keyword that allows a user to modify a variable outside of the current scope. It is used to create global variables from a non-global scope.
We can use global keyword for the following 2 purposes:
To declare global variable inside function
To make global variable available to the function so that we can perform required modifications.
Note: If global variable and local variable having the same name then we can access global variable inside a function as follows.
Passing a Group of Elements to a Function
To pass a group of elements like numbers or strings, we can accept them into a list and then pass the list to the function where the required processing can be done.
