为什么这个出错啊！求解

这个一个剪刀石头布的游戏怎么会错？
代码：

import ramdom
win = '你赢了!'
not_win = '你输了!'
haha = '平局'
print('剪刀石头布')
random_1 = random.randint(1,3)
AI = str(random_1)
print('''
1=剪刀
2=石头
3=布
''')
player = str(input('请出:'))
if AI == '1':
    print('Al出了剪刀')
elif AI == '2':
    print('AI出了石头')
elif AI == '3':
    print('AI出了布')

if AI == '1' and player == '1':#平
    print(haha)
elif AI == '1' and player == '2':#剪刀 石头
    print(win)
elif AI == '1' and player == '3':#剪刀 布
    print(not_win)
elif AI == '2' and player == '1':#石头 剪刀
    print(not_win)
elif AI == '2' and player == '2':#平
    print(haha)
elif AI == '2' and player == '3':#石头 布
    print(wim)
elif AI == '3' and player == '1':#布 剪刀
    print(wim)
elif AI == '3' and player == '2':#布 石头
    print(not_wim)
elif AI == '3' and player == '3':#平
    print(haha)

应该为import random
input外点str可以去掉，加这个没用

import 写错了

提醒：
其实input 不用str无论用户输入啥都是字符
