Do you mean maketrans() from the string module? I didn't know about
it, but I've tried it and it works too:

>>> import string
>>> unsafe_chars = "/#()[]!@$%^&*{}\'\"`?<>| \t\n"
>>> alt_chars = "_________________________"
>>> table = string.maketrans(unsafe_chars, alt_chars)
>>> "a/b/c".translate(table)
'a_b_c'
>>>
