You may use str.translate to replace/remove all undesired characters:

py> import string
py> valid = string.ascii_letters+string.digits+'.'
py> invalid = ''.join(chr(x) for x in range(256) if chr(x) not in valid)
py> table = string.maketrans(invalid, '_'*len(invalid))
py> x = 'http://docs.python.org/library/string.html'
py> x.translate(table)
'http___docs.python.org_library_string.html'

See http://docs.python.org/library/stdtypes.html#str.translate
