剑指offer——2

题目描述

请实现一个函数，将一个字符串中的每个空格替换成“%20”。例如，当字符串为We Are Happy.则经过替换之后的字符串为We%20Are%20Happy。  

# -*- coding:utf-8 -*-
class Solution:
    # s 源字符串
    def replaceSpace(self, s):
        # write code here
        n=len(s)
        for i in range(n):
            if s[i]==' ':
                s=s.replace(s[i],'%20')
        return s
        
while 1:
    try:
        ss=Solution()
        s=raw_input()
        print(ss.replaceSpace(s))
    except:
        break
