I have run into an error during this exercise which I don’t understand. Down below are the instructions.

1.First, def a function called cube that takes an argument called number. Don’t forget the parentheses and the colon!

Make that function return the cube of that number (i.e. that number multiplied by itself and multiplied by itself once again).

Define a second function called by_three that takes an argument called number.

if that number is divisible by 3, by_three should call cube(number) and return its result. Otherwise, by_three should return False.

Don’t forget that if and else statements need a : at the end of that line!

My code (below) gives this error:

cube(1) resulted in an error: maximum recursion depth exceeded

```
def cube(number):
number ** 3
return cube(number)
def by_three(number):
if number % 3 == 0 :
cube(number)
return (number)
else:
return False
```

What does this error mean? Also, are there any suggestions to being able to fix it?
