Re^3: Five Ways to Reverse a String of Words (C#, Perl 5, Perl6, Ruby, Haskell)

[ambrus]

You don't need [word for word in ...]. That's just the same as map { $_ } ... in perl, an identity op on lists (more or less).

>>> def reverseWords(words):
...     return ' '.join(words.split()[::-1])
... 
>>> reverseWords("  one   two three four    ")
'four three two one'
