Python Example of function as return type: Here, we are going to learn how we can return a function as return value in Python?
Submitted by Pankaj Singh, on October 14, 2018

Example:

Here, we are defining two function foo() and koo(), function koo() will return as a value (return value of the function).

The calling statement is x=koo() - where, koo() is first function and the return value of koo() (that is the function foo()) will store in the x (which is also a function).

Code:

# defining a function
def foo():
    print("I am Foo")

# defining an another function
# it will return function as a return value
def koo():
    return foo

# function calling and assigning return value
# in x
x=koo()
x()

Output

I am Foo
