You get this when the function gets the right object but the value of
that object is not correct. For example int() will attempt to create an
integer object from a string object. However if that string is not a
number represented as a sting you run into a ValueError.

int('test')

Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    int('test')
ValueError: invalid literal for int() with base 10: 'test'

When we give it the string representation of 123 int() will convert the
string to an integer.

int('123')
123
