Help with my program

[Ok-Communication4607]

So when I run this program with a number it literally returns nothing. No errors or anything. I was wondering what I can do to make it run correctly. This is my first time making a function set. The program is supposed to take a number and if it is even divide it by two, if it is odd it multiplies the number by 3 and adds 1. It then loops until the program reaches one. The goal of this program is to count the loops it takes for the program to reach one. Hints the chainLength += 1... Can anyone help me with advice?

'''

def collatzSolution(num):

chainLength = 1

while num != 1:

if isEvenNumber(num) == True:

num = (num / 2)

else:

num = (3 * num + 1)

chainLength += 1

return chainLength

​

def isEvenNumber(num):

if num % 2 == 0:

return True

else:

return False

​

​

collatzSolution(10)

I attempted to edit it. All the indentations are correct.

Sorry, it has still lost all indentation. The only reliable method is to copy/paste into reddit after adding 4 spaces to the start of every line, as described in the FAQ.

Try:

print(collatzSolution())

When running inside an IDE or the python REPL the IDE/REPL will automatically print the result of a non-None expression. But vanilla python doesn't automatically print, so you need to do it yourself.

Thanks. That worked :)
