Why does my code not return anything

Question

fairly new to programming and trying to learn Python at the moment. I have this code and I don\'t understand why I don\'t get a return value :(

balance = 3200

Answer 1

First you should add return ba to function f to make f return someting:

def f(x):
    m = 0
    ba = balance 
    while m < 12: 
        ba = (ba - x)*monthlyInterestRate 
        m += 1
    retrun ba

Then, add bisection() at the last of your script file to call it:

bisection()
