用Python实现一个猜密码的程序

完整代码：`

在这里插入代码片
```import random
print("-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --密码猜猜猜-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --")
print("正确密码由四个互不相同的大写字母组成，猜猜看呐")
letterList = ["A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z"]
passwordList = []
count = 0
gjr = ""
while True:
    index = random.randint(0,len(letterList)-1)
    letter = letterList[index]
    passwordList.append(letterList[index])
    letterList.pop(index)
    count += 1
    if count == 4:
        break
while True:    
    user = input("请输入密码:")
    userList = list(user)
    if len(userList) == 4:
        posCorrect = 0
        if passwordList[0] == userList[0]:
            posCorrect += 1
        if passwordList[1] == userList[1]:
            posCorrect += 1
        if passwordList[2] == userList[2]:
            posCorrect += 1
        if passwordList[3] == userList[3]:
            posCorrect += 1
        pos_right = ("位置对了:" + str(posCorrect))
        letterCorrect = 0
        if userList[0] in passwordList:
            letterCorrect += 1
        if userList[1] in passwordList:
            letterCorrect += 1
        if userList[2] in passwordList:
            letterCorrect += 1
        if userList[3] in passwordList:
            letterCorrect += 1
        letter_right = ("字母对了:" + str(letterCorrect))
        if userList == passwordList:
            print("猜对了，你真棒")
            break
        else:
            print(pos_right + letter_right)
    else:
        print("别乱输")
