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)

希望本文所述对大家的Python程序设计有所帮助。
