Call function inside function python

” These nested functions have access to the variables and parameters of the outer (enclosing) function, creating a scope hierarchy.

A function can have one or more inner functions. 

Syntax:

// Outer function function outerFunction() { // Nested function function nestedFunction() { // Function logic here } // Call the nested function nestedFunction(); // Rest of the outer function logic } // Call the outer function outerFunction();

Approach:

• Write one function inside another function.
• Make a call to the inner function in the return statement of the outer function.
• Call it fun(a)(b) where a is a parameter to the outer and b is to the inner function.
• Finally, return the combined output from the nested function.

Example 1: This example uses the approach discussed above. 

Example 2: This example uses the approach discussed above, but here the nested function is created differently than the previous one.
