CALLING A FUNCTION
The process of using a function at the Python prompt or in a program is known as Calling the function.
While calling a function, we must use its correct name and pass the required number of arguments
to it. If the function returns a value, care must be taken to store the value in a variable.
For example, the statement to call the area_square function as described earlier in the chapter is
SqArea = area_square(20), or

>>> print(area_square(10))
