string.translate() with unicode data in python

by

The translate method work differently on Unicode objects than on byte-string objects:

>>> help(unicode.translate)

S.translate(table) -> unicode

Return a copy of the string S, where all characters have been mapped
through the given translation table, which must be a mapping of
Unicode ordinals to Unicode ordinals, Unicode strings or None.
Unmapped characters are left untouched. Characters mapped to None
are deleted.

So your example would become:

remove_punctuation_map = dict((ord(char), None) for char in string.punctuation)
word_list = [s.translate(remove_punctuation_map) for s in value_list]

Note however that string.punctuation only contains ASCII punctuation. Full Unicode has many more punctuation characters, but it all depends on your use case.
