Question

Subject: Python Programming

My instructions say:

" Define a higher order function mult_by that takes one number n as input and returns a function. The returned function takes one parameter x as input, and when called returns the product n∗x.

Expected Output
The following code snippet may be helpful for design and debugging. It illustrates code that creates two functions: one multiplies its input by π and the other multiplies it's input by e."

I am a bit confused as to what I need to do here. Here is my code. Please help. Thank you

import math

def main():
f = mult_by(math.pi)
g = mult_by(math.e)
print(f(6))
print(g(8))
print(f(10))
print(g(12))

if __name__ == "__main__":
main()
