Python数字猜谜游戏不起作用[重复]

Question

所以我想涉足开发游戏和模组等，所以我开始研究编程语言并决定选择 python 作为我的起始语言，因为它看起来相当简单且非常有效。我已经做了大约两天了，并利用我目前的知识尝试编写猜谜游戏的代码！在您继续阅读之前，这是我的游戏的代码：

import random

print("Welcome to a guessing game!")
print ("You have 3 try's to guess the correct number!")


number = raw_input ("Pick a number between 1 and 10!: " )
compnumber = random.randint (1,10)
enter = "Please press enter to exit..."
winner = "Congrats your a Winner!"
loser_high = "Uh-Oh!  That Number is to high!  Guess again!"
loser_low = "Uh-Oh!  That number is to low!  Guess again!"
demand = "Pick a number between 1 and 10!: "
game_over = "Sorry, you have lost the game!"


#Guess Number One
if number == compnumber :
    print (winner)
elif number != compnumber and number > compnumber :
    print (loser_high)
    guess2 = raw_input ()
elif number != compnumber and number < compnumber :
    print (loser_low)
    guess2 = raw_input (demand)

#Guess Number Two
if guess2 == compnumber :
    print (winner)
elif guess2 != compnumber and guess2 > compnumber :
    print (loser_high)
elif guess2 != compnumber and guess2 < compnumber :
    print (loser_low)
    guess3 = raw_input (demand)

#Guess Number Three
if guess3 == compnumber :
    print (winner)
elif guess3 != compnumber and guess3 > compnumber :
    print (loser_high)
elif guess3 != compnumber and guess3 < compnumber :

这只是一个简单的 40 行代码，我非常自豪:D

所以无论如何，这是我的问题。当我运行应用程序时，我一般不会收到任何语法错误或任何错误，但是当我输入我的第一个猜测时，它总是说我的猜测太高了......当我再次尝试时，它说同样的事情然后控制台关闭...这是为什么？

另外，如果有人能给我一些关于如何简化/压缩我当前代码的建议，请在下面发布，如果有人有一些学习更高级 python 的教程，请告诉我！谢谢！！！

Answer 1

您的问题是raw_input() 返回一个字符串，而random.randint() 返回一个整数。在 Python 2 中，比较不同类型的对象是合法的，字符串的比较总是高于整数。

您需要将用户输入转换为ints，然后它应该可以工作。

guess = int(raw_input())

此外，您不应通过复制/粘贴大致相同的代码三次来实现循环。使用for 或while 循环：

for attempt in range(3):
    guess = int(raw_input(demand))
    if guess == compnumber:
        print winner
        break          # abort the loop
    elif guess > compnumber:
        print loser_high
    else:
        print loser_low
else:
    print game_over

Answer 2

我怀疑问题在于原始输入是一个字符串，而随机值是一个整数。尝试将第 7 行更改为：

number = int(raw_input("Pick a number between 1 and 10!: ").strip())

这个修改做了两件事：

• 删除输入值周围的所有空格（使用.strip()）
• 将字符串转换为整数类型（使用int()）

您还需要在接受用户输入的其他行上执行类似的操作。

Answer 3

您需要将raw_input 返回的字符串转换为数字。您还可以为整个游戏设置一个循环并防止代码重复。另一件事是，在 if 条件中检查 number == compnumber 后，您不必在 else 部分检查 number != compnumber：

# ....

for i in range(3):
    number = int(raw_input ("Pick a number between 1 and 10!: " ))
    if number == compnumber :
        print (winner)
        exit(0)
    elif number > compnumber :
        print (loser_high)
    elif number < compnumber :
        print (loser_low)
    print "Guess again!"

Answer 4

import random

LOSER_HIGH, LOSER_LOW, WINNER = 1, -1, 0
GUESS_TIMES = 3

WIN_STR = "Congrats your a Winner!"
GAMEOVER_STR = "Sorry, you have lost the game!"
LOSER_HIGH_STR = "Uh-Oh!  That Number is to high!  Guess again!"
LOSER_LOW_STR = "Uh-Oh!  That number is to low!  Guess again!"
DEMAND_STR = "Pick a number between 1 and 10!: "


def do_guess(number, compnumber):
    if number > compnumber:
        return LOSER_HIGH
    elif number < compnumber:
        return LOSER_LOW
    else:
        return WINNER

def main():
    compnumber = random.randint (1,10)

    print ("Welcome to a guessing game!")
    print ("You have 3 try's to guess the correct number!") 

    for i in xrange(GUESS_TIMES):
        number = int(raw_input(DEMAND_STR))
        ret = do_guess(number, compnumber)
        if ret == LOSER_HIGH:
            print LOSER_HIGH_STR
        elif ret == LOSER_LOW:
            print LOSER_LOW_STR
        else:
            print WIN_STR
            break
    else:
        print GAMEOVER_STR

    raw_input("Please press enter to exit...")

if __name__ == '__main__':
    main()
