Python字符串替换实例分析

本文实例讲述了python/' target='_blank'>python字符串替换的方法。分享给大家供大家参考。具体如下：

单个字符替换

s = 'abcd'a = ["a", "b", "c"]b = ["c", "d", "e"]import strings.translate(string.maketrans(''.join(a),''.join(b)))print s

输出结果为：abcd

字符串替换，改善版

s = "hello, i'm mouren, hehe~~,hehe~~mourenmouren"a = ["mouren", "hehe"]b = ["mr", "hoho"]import redic = dict(zip(a,b))pattern = re.compile('(' + '|'.join(a) + ')')s = pattern.sub(lambda a:dic[a.group()], s)print s

输出结果为：hello, i'm mr, hoho~~,hoho~~mrmr

希望本文所述对大家的Python程序设计有所帮助。
