s = hello world! how are you? 0 # short version print filter(lambda c: c.isalpha(), s) # faster version for long ascii strings: id_tab = .join(map(chr, xrange(256))) tostrip = .join(c for c in id_tab if c.isalpha()) print s.translate(id_tab, tostrip) # using regular expressions print re.sub([^a-za-z], , s)
