>>> s = "NHoBwA RyAoSuB AsAeHeH AiBtH,A CnRoAwD HyBoAuC HdRoCnH'AtB"
>>> s.translate(None, "BADCHARS")
"Now you see it, now you don't"
>>> s.replace("BADCHARS", "")
"NHoBwA RyAoSuB AsAeHeH AiBtH,A CnRoAwD HyBoAuC HdRoCnH'AtB"
i. e. you have to replace() for every char in "BADCHARS":
>>> reduce(lambda x, y: x.replace(y, ""), "BADCHARS", s)
"Now you see it, now you don't"
+1, btw.
