本文实例讲述了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
1
2
3
4
5
6
|
s = 'abcd'
a = [ "a" , "b" , "c" ]
b = [ "c" , "d" , "e" ]
import string
s.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 re
dic = 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。
