Python 多个数字猜谜游戏

问题描述

我正在尝试创建一个包含多个数字的猜数字游戏.计算机生成 1 到 9 之间的 4 个随机数，然后用户有 10 次机会猜出正确的数字.我需要将反馈显示为 YYYY 表示猜出的 4 个正确数字，YNNY 表示猜出的第一个和最后一个数字等(你明白了).下面的代码不断返回说IndexError: list index out of range.

I am trying to create a number guessing game with multiple numbers. The computer generates 4 random numbers between 1 and 9 and then the user has 10 chances to guess the correct numbers. I need the feedback to display as YYYY for 4 correct numbers guessed, YNNY for first and last number guessed etc. (you get the point). the code below keeps coming back saying IndexError: list index out of range.

from random import randint

guessesTaken = 0
randomNumber = []

for x in range(4):
        tempNumber = randint(1, 9)
        randomNumber.append(tempNumber)

Guess = []
Guess.append(list(input("Guess Number: ")))

print(randomNumber)
print(Guess)

if randomNumber[0] == Guess[0]:
    print("Y")
elif randomNumber[1] == Guess[1]:
    print("Y")
elif randomNumber[2] == Guess[2]:
    print("Y")
elif randomNumber[3] == Guess[3]:
    print("Y")
elif randomNumber[0] != Guess[0]:
    print("N")
elif randomNumber[1] != Guess[1]:
    print("N")
elif randomNumber[2] != Guess[2]:
    print("N")
elif randomNumber[3] != Guess[3]:
    print("N")

推荐答案

你需要四次猜测来匹配随机数，你也可以使用 list comp 缩短你的代码:

You need four guesses to match for random numbers, you can also shorted your code using a list comp:

from random import randint

guessesTaken = 0
randomNumber = []

Guess = []
for x in range(4):
        tempNumber = str(randint(1, 9)) # compare string to string
        randomNumber.append(tempNumber)
        Guess.append(input("Guess Number: "))

print("".join(["Y" if a==b else "N" for a,b in zip(Guess,randomNumber)]))

您还可以使用 enumerate 检查匹配索引处的元素:

You can also use enumerate to check elements at matching indexes:

print("".join(["Y" if randomNumber[ind]==ele else "N"  for ind, ele in enumerate(Guess)]))

给用户一个循环的猜测:

To give the user guesses in a loop:

from random import randint

guessesTaken = 0
randomNumber = [str(randint(1, 9))  for _ in range(4)] # create list of random nums

while guessesTaken < 10:
    guesses = list(raw_input("Guess Number: ")) # create list of four digits
    check = "".join(["Y" if a==b else "N" for a,b in zip(guesses,randomNumber)])
    if check == "YYYY": # if check has four Y's we have a correct guess
        print("Congratulations, you are correct")
        break
    else:
        guessesTaken += 1 # else increment guess count and ask again
        print(check)
