Catching a ZeroDivisionError

There is a function foo$($n$)$ that takes an integer n does some calculations that involve divisions. Sadly, the people who wrote foo sometime divide by zero. This means the code sometimes throws a ZeroDivisionError.

Write a function called safeFoo$($n$)$ that runs foo$($n$).$ If it runs successfully, it should return whatever foo returned. If it raises a ZeroDivisionError, it should return $0.$ If it raises any other kind of error, it should return None.

A sample Python run might look like this:

$>$ foo$(1)$ # This time it works

$20$

$>$ foo$(2)$ # This time it divides by zero

Traceback $($most recent call last$)$:

File $"",$ line $1,$ in

ZeroDivisionError

$>$ foo$(3)$ # This time it has a Key Error

Traceback $($most recent call last$)$:

File $"",$ line $1,$ in

KeyError $\text{'}$x$\text{'}$

$>$ safeFoo$(1)$

$20$

$>$ safeFoo$(2)$

$0$

$>$ safeFoo$(3)$

None

Your code snippet should define the following variables:

Name Type Description

safeFoo function A function that safely calles foo
