本文實例講述了python清除字符串裡非字母字符的方法。分享給大家供大家參考。具體如下:
?
1 2 3 4 5 6 7 8 9 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)希望本文所述對大家的Python程序設計有所幫助。
