Python 一个妹子要求我重写[::-1]

# -*- coding: UTF-8 -*-

#重写[::1]实现！

list_result = []
l_string = ''

def reserved(text):

global l_string

for string in text:
list_result.append(string)
x = len(list_result)

while x > 0:

x -=1

l_string += list_result[x]

print l_string

if __name__ == '__main__':
reserved("I Like Python!")
