這是一個數字猜謎游戲，num_check函式第一次運行良好，但不會運行任何第二次嘗試。有誰知道為什么？

import random

# Define function - Number Generator
def num_gen():

    num = random.randrange(1, 101)
    return num

# Define function - Number Check
def num_check(x, y):

    result = ''
    if x > y:
        result = 'high'
    elif x < y:
        result = 'low'
    else:
        result = 'correct'
    return result

# Call - Number Generator
num = num_gen()

# Input - Guess
guess = int(input('Please guess a number between 1 and 100: '))

att = 1

# Process - Guess and Display Result
result = num_check(guess, num)

if result == 'high':

    guess = int(input('Your guess was HIGH! Please guess another number between 1 and 100: '))
    att  = 1
    result = num_check(guess, num)

elif result == 'low':

    guess = int(input('Your guess was LOW! Please guess another number between 1 and 100: '))
    att  = 1
    result = num_check(guess, num)

else:

    print('Your guess was CORRECT! You got it in '   str(att)   ' attempts!')

從控制臺獲取輸入后，您應該創建一個回圈，當猜測的數字等于輸入時中斷。例如：

# Input - Guess
guess = int(input('Please guess a number between 1 and 100: '))

att = 1


# Process - Guess and Display Result
result = num_check(guess, num)

while result != guess:

    if result == 'high':

        guess = int(input('Your guess was HIGH! Please guess another number between 1 and 100: '))
        att  = 1
        result = num_check(guess, num)

    elif result == 'low':

        guess = int(input('Your guess was LOW! Please guess another number between 1 and 100: '))
        att  = 1
        result = num_check(guess, num)
        
    else:
        break
    
print('Your guess was CORRECT! You got it in '   str(att)   ' attempts!')

修改后代碼如下：

import random

# Define function - Number Generator
def num_gen():

    num = random.randrange(1, 101)
    return num

# Define function - Number Check
def num_check(x, y):

    result = ''
    if x > y:
        result = 'high'
    elif x < y:
        result = 'low'
    else:
        result = 'correct'
    return result

# Call - Number Generator
num = num_gen()

# Input - Guess
guess = int(input('Please guess a number between 1 and 100: '))

att = 1


# Process - Guess and Display Result
result = num_check(guess, num)

while result != guess:

    if result == 'high':

        guess = int(input('Your guess was HIGH! Please guess another number between 1 and 100: '))
        att  = 1
        result = num_check(guess, num)

    elif result == 'low':

        guess = int(input('Your guess was LOW! Please guess another number between 1 and 100: '))
        att  = 1
        result = num_check(guess, num)
        
    else:
        break
    
print('Your guess was CORRECT! You got it in '   str(att)   ' attempts!')

這是因為python程式是從上到下運行的，到了底部就結束了，就停止運行了。要停止此訂單，我們有多種不同的方法：

我們可以呼叫函式，就像您在程式中所做的那樣。

選擇控制結構：Asif 陳述句

迭代控制結構：作為回圈

最后一個是您在此解決方案中需要的。用正確的條件將代碼包裝在一個while回圈中，在你的例子中，這將是

# Input - Guess
guess = int(input('Please guess a number between 1 and 100: '))

att = 1

# Process - Guess and Display Result
result = num_check(guess, num)

if result == 'high':

    guess = int(input('Your guess was HIGH! Please guess another number between 1 and 100: '))
    att  = 1
    result = num_check(guess, num)

elif result == 'low':

    guess = int(input('Your guess was LOW! Please guess another number between 1 and 100: '))
    att  = 1
    result = num_check(guess, num)

else:

    print('Your guess was CORRECT! You got it in '   str(att)   ' attempts!')

最好的方法是使用 will 回圈，如下所示：

while guess != num:

你應該使用while True:, 因為你的猜測代碼在沒有它的情況下只運行一次

import random

# Define function - Number Generator
def num_gen():

    num = random.randrange(1, 10)
    return num

# Define function - Number Check
def num_check(x, y):

    result = ''
    if x > y:
        result = 'high'
    elif x < y:
        result = 'low'
    else:
        result = 'correct'
    return result

# Call - Number Generator
att = 1
num = num_gen()
while True:
    # Input - Guess
    guess = int(input('Please guess a number between 1 and 100: '))
    # Process - Guess and Display Result
    result = num_check(guess, num)

    if result == 'high':
        print('Your guess was HIGH! Please guess another number between 1 and 100: ')
        att  = 1

    elif result == 'low':
        print('Your guess was LOW! Please guess another number between 1 and 100: ')
        att  = 1

    else:
        print('Your guess was CORRECT! You got it in '   str(att)   ' attempts!')
        break

如果您沒有在程式中使用任何回圈，您怎么能期望它運行超過 1 次。例如，在這種情況下，您應該使用while loop，然后只有它會一次又一次地提示用戶并檢查條件，將game變數設定為True。當數字匹配時，只需將游戲變數設定為False，它將結束回圈。

import random

# Set the game variable initially to be True
game = True

# Define function - Number Generator
def num_gen():

    num = random.randrange(1, 101)
    return num

# Define function - Number Check
def num_check(x, y):

    result = ''
    if x > y:
        result = 'high'
    elif x < y:
        result = 'low'
    else:
        result = 'correct'
    return result

# Call - Number Generator
num = num_gen()

# Input - Guess
guess = int(input('Please guess a number between 1 and 100: '))

att = 1

# Process - Guess and Display Result
result = num_check(guess, num)

while game:

    if result == 'high':

        guess = int(input('Your guess was HIGH! Please guess another number between 1 and 100: '))
        att  = 1
        result = num_check(guess, num)

    elif result == 'low':

        guess = int(input('Your guess was LOW! Please guess another number between 1 and 100: '))
        att  = 1
        result = num_check(guess, num)

    else:

        print('Your guess was CORRECT! You got it in '   str(att)   ' attempts!')
        game = False
