python 字符串翻转
1. 使用字符串切片，步长设置为-1
1 # coding:utf-8 2 3 s = “abcdefg123” 4 r = s[::-1] 5 print(r)
2. 双端队列
1 # coding:utf-8 2 from collections import deque 3 4 5 def string_reverse4(string): 6 d = deque() 7 d.extendleft(string) 8 print ''.join(d) 9 10 11 string_reverse4("abcdefg123")
3. 使用列表的reverse方法
1 # coding=utf-8 2 3 m = list(s) 4 m.reverse() 5 result = "".join(m)
