Higher Order Functions

A function that either:

• Accepts a function as an argument OR
• Returns a function

In python functions are treated as an object.

Example 1:

def loud(text):
    return text.upper()
def quiet(text):
    return text.lower()
def hello(text):
    text = func("Hello")
    print(text)
hello(loud)
hello(quiet)

Example 2:

def divisor(x):
    def dividend(y):
        return y/x;
divide = divisor(2)
print(divide(10)) # 5.0


"""
10/2 = 5

10 = dividend
2 = divisor
5 = quotient
