我正在尝试使用我的第一种脚本语言：python。我目前正在制作一个小游戏，您可以在其中猜测 1-100 的预定数字。它还会告诉您正确答案是更大还是更小。目前我的代码总是返回正确的数字较小，而事实并非如此。

编辑：非常感谢你帮助我！

import random

print("this is a game made by Sven")
print("you're supposed to guess the right number. it is between 0 & 101.")
print("lucky for you, you're getting hints.")
print("succes!")

rightnumber = (random.randint(1, 100))
print(rightnumber)

gok = int(input("type your guess here and press enter"))

def compareguess():
    if gok > rightnumber:
        print("wrong! the right number is smaller :)")
    elif gok == rightnumber:
        print("WOW! you guessed right!")
    else:
        print("wrong! the right number is bigger.")
compareguess()

def guessAgain():
    int(input("try again. type your guess and press enter."))
    compareguess()
    if rightnumber == gok:
        print("that was it! you won!")
    else: guessAgain()


if rightnumber == gok:
    print("that was it! you won!")
else: guessAgain()

您可以gok作为参数传递以避免全局变量。

问题是：

当您再次输入时：int(input("try again. type your guess and press enter."))，您不会将值分配给任何东西。所以gok保持不变，总是更大或更小

import random

print("this is a game made by Sven")
print("you're supposed to guess the right number. it is between 0 & 101.")
print("lucky for you, you're getting hints.")
print("succes!")

rightnumber = (random.randint(1, 100))

gok = int(input("type your guess here and press enter"))

def compareguess(gok):
    if gok > rightnumber:
        print("wrong! the right number is smaller :)")
    elif gok == rightnumber:
        print("WOW! you guessed right!")
    else:
        print("wrong! the right number is bigger.")
compareguess(gok)

def guessAgain():
    gok=int(input("try again. type your guess and press enter."))
    compareguess(gok)
    if rightnumber == gok:
        print("that was it! you won!")
    else: guessAgain()


if rightnumber == gok:
    print("that was it! you won!")
else: guessAgain()

另外，不要使用递归。相反，使用while循环。没有递归的缩短代码：

import random

print("this is a game made by Sven")
print("you're supposed to guess the right number. it is between 0 & 101.")
print("lucky for you, you're getting hints.")
print("succes!")

rightnumber = (random.randint(1, 100))
while True:
    gok = int(input("type your guess here and press enter"))
    if gok > rightnumber:
        print("wrong! the right number is smaller :)")
    elif gok == rightnumber:
        print("WOW! you guessed right!")
        break
    else:
        print("wrong! the right number is bigger.")

试试这个代码

import random

print("this is a game made by Sven")
print("you're supposed to guess the right number. it is between 0 & 101.")
print("lucky for you, you're getting hints.")
print("succes!")

rightnumber = (random.randint(1, 100))
print(rightnumber)

gok = int(input("type your guess here and press enter"))

def compareguess(gok):
    if gok == rightnumber:
        print("WOW! you guessed right!")
    elif gok > rightnumber: 
        print("wrong! the right number is smaller :)")
    else:
        print("wrong! the right number is bigger.")
compareguess(gok)

def guessAgain():
    gok = int(input("try again. type your guess and press enter."))
    compareguess(gok)
    if rightnumber == gok:
        print("that was it! you won!")
    else: guessAgain()


if rightnumber == gok:
    print("that was it! you won!")
else: guessAgain()

问题在于参数的范围。第一个猜测全局存储在gok. 无论是小还是大，compareguess都会打印出正确的信息。但是当你打电话时，guessAgain你不会在任何地方保存新的猜测，所以值gok仍然是旧的。即使您要保存它，范围也不会正确，因此您不会在compareguess.

所以一个可能的解决方案是gok作为参数传递给compareguess（我也rightnumber作为参数添加）。

def compareguess(gok, rightnumber):
    if gok > rightnumber:
        print("wrong! the right number is smaller :)")
    elif gok == rightnumber:
        print("WOW! you guessed right!")
    else:
        print("wrong! the right number is bigger.")

现在会运行 -

while rightnumber != gok:
     gok=int(input("try again. type your guess and press enter."))
     compareguess(gok, rightnumber)

你可以用这个。它会一直询问，直到您输入正确的数字。

import random

print("this is a game made by Sven")
print("you're supposed to guess the right number. it is between 0 & 101.")
print("lucky for you, you're getting hints.")
print("succes!")

rightnumber = random.randint(1, 100)
print(rightnumber)

def guess():
    gok = int(input("type your guess here and press enter: "))

    if gok > rightnumber:
        print("wrong! the right number is smaller :)")
        guess()
    
    elif gok == rightnumber:
        print("WOW! you guessed right!")
        print("that was it! you won!")
    
    else:
        print("wrong! the right number is bigger.")    
        guess()

guess()

你的compareguess功能

def compareguess():
    if gok < rightnumber:
        print("wrong! the right number is smaller :) ")
    elif gok == rightnumber:
        print("WOW! you guessed right!")
    else:
        print("wrong! the right number is bigger. ")

你的guessAgain功能

def guessAgain():
    global gok
    gok = int(input("try again. type your guess and press enter."))
    compareguess()
    if rightnumber == gok:
        print("that was it! you won!")
    else:
        guessAgain()
