A value can have a different name inside a function when it is passed as a parameter. Consider the following session: >>> def get_first_word(whatever_you_like): ... return whatever_you_like[0] ... >>> names = "peter paul mary".split() >>> words = "nobody expects the spanish inquisition".split() >>> get_first_word(names) 'peter' >>> get_first_word(words) 'nobody' Both the 'names' and the 'words' list of strings are referred to as 'whatever_you_like' inside the get_first_word() function.
