Root Cause

Trying to iterate over a non-iterable. Common: for x in some_int, or sum(x) where x is not a list.

  2. 88% success If you need to iterate over digits/chars, convert first: str(num) or [num] 
    str(num) or [num]

Dead Ends

Common approaches that don't work:

    Usually the variable is wrong type, not missing __iter__
