   What happens when a function is called in Python?

   • Once the end of the function is reached, Python jumps back to where the function was called from and continues with the following line! In this case, there is no following line, so the program ends. In short, a function call is not a jump or ‘go to’ but a call to a piece of reusable code that returns to where it was called from.

   What is a follow python function?

   • Follow Python Functionsis a block of statements that return the specific task. The idea is to put some commonly or repeatedly done tasks together and make a function so that instead of writing the same code again and again for different inputs, we can do the function calls to reuse code contained in it over and over again.
