easy way to remove nonprintable chars from string

[Don Hiatt]

Greetings,

Is there an easy way to remove multiple non-printable
(e.g. "not strings.printab le") from a string? Perhaps
something like foo.replace(lis t_of_nonprintab les, '')
if it only existed? :-)

Cheers,

don

help(str.transl ate) translate(...)
S.translate(tab le [,deletechars]) -> string

Return a copy of the string S, where all characters occurring
in the optional argument deletechars are removed, and the
remaining characters have been mapped through the given
translation table, which must be a string of length 256.
s_identity=''.j oin([chr(i) for i in range(256)]) # the 'table' you

need

This seems to work. Not sure how fast it'd be, though.

def stripNoPrint(st r):
results = ""
for char in str:
if string.printabl e.find(char):
results += char
return results

Check out the string module's translate function.
