Attributions getting confusing, so I have snipped and rewritten:

It's just a cognitive difference--in my example, literal() would
return a string if given a number and return a number if given a
string (in each case, the output would be precisely what you would get
had you written the input as a literal in the other format, hence the
'literal' name). In your example, str() does the same thing--but I
would suggest that a function named 'str' should always return a
string.
