python清除字符串里非字母字符的方法
本文实例讲述了python清除字符串里非字母字符的方法。分享给大家供大家参考。具体如下:
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。
