Python if and else语句不是预期的输出

我注意到一些错误。 首先,您不需要if-trument==3或2,因为您使用的是while循环(while循环基于最初的条件)。 第二,最好将“break”积分为一个无限循环。 而循环从0开始,在2结束(取3个值)。

我为你重写了代码。

def check_guess(guess, answer):
global score
global name
still_guessing = True
attempt = 0
while still_guessing and attempt < 2:
    if guess == answer:
        print('Correct wow, i expected worse from someone named %s' % name)
        if attempt == 0:
            score = score + 3
        elif attempt == 1:
            score = score + 2
        elif attempt == 2:
            score = score + 1
        still_guessing = False
    elif attempt <= 1:
        print('HAAAAAAAAAAAAAAAAAAAAAAAAAAAA IMAGINE NOT GETTING THAT RIGHT!!!')
        print('L bozo + ratio')
        guess = input('Try again ')
        attempt = attempt + 1
    break

print('the correct answer was %s' % answer)
print('There is always next time!!')
still_guessing = False

要测试代码,请添加 print("pass OK")

score = 0
print('Welcome to the animal quiz')
print()
print('In this game you will have to guess the animal')
name = input('What is your name? ')
print('Cool name, I feel like i heard of it before hmmm %s..' % name)
print()
print('Enough stalling onto the game!!!')
guess1 = input('Which bear lives in the north pole ')
check_guess(guess1.strip().lower(), 'polar bear')
print("pass OK")

别忘了投票:)(斋月卡里姆!!!)

在你的while循环中 “尝试”永远不会变为3,因此代码无法跳转到下一部分 if attmpt == 3 所以在while循环中 elif 情况应该是 elif attempt <= 2: 然后 attempt = attempt + 1 可以达到3

使用下面的代码它对我有用。

def check_guess(guess, answer):
    global score
    global name
    still_guessing = True
    attempt = 0
    while still_guessing and attempt < 3:
        if guess == answer:
            print('Correct wow, i expected worse from someone named %s' % name)
            if attempt == 0:
                score = score + 3
            elif attempt == 1:
                score = score + 2
            elif attempt == 2:
                score = score + 1
            still_guessing = False
        elif attempt <= 2:
            print('HAAAAAAAAAAAAAAAAAAAAAAAAAAAA IMAGINE NOT GETTING THAT RIGHT!!!')
            print('L bozo + ratio')
            guess = input('Try again ')
            attempt = attempt + 1
    if attempt == 3:
        print('the correct answer was %s' % answer)
        print('There is always next time!!')
        still_guessing = False
score = 0
print('Welcome to the animal quiz')
print()
print('In this game you will have to guess the animal')
name = input('What is your name? ')
print('Cool name, I feel like i heard of it before hmmm %s..' % name)
print()
print('Enough stalling onto the game!!!')
guess1 = input('Which bear lives in the north pole ')
check_guess(guess1.strip().lower(), 'polar bear')

我认为 elif 贝娄应该评估<=2,而不是1:

        elif attempt <= 2:

但最后一条“再试一次”的信息仍然打印出来。您可以在“重试”消息之前设置一个尝试检查条件来解决这个问题。如果条件求值为True,则中断循环:

        elif attempt <= 2:
            print('HAAAAAAAAAAAAAAAAAAAAAAAAAAAA IMAGINE NOT GETTING THAT RIGHT!!!')
            print('L bozo + ratio')
            attempt = attempt + 1
            if attempt > 2:
                break            
            guess = input('Try again ')

在这种情况下,请记住调整您的状态,因为不再需要尝试检查。

如果可以的话,我在代码中做了一些重构,因此您可以查看其他方法来实现相同的目标。

def check_guess(guess, answer, attempts):
    global score
    global name
    while True:
        if guess == answer:
            print('Correct wow, i expected worse from someone named %s' % name)
            score = [0, 1, 2, 3]
            final_score = score[attempts]
            print(f'Score: {final_score}')
            break

        attempts -= 1

        if attempts == 0:
            print('the correct answer was %s' % answer)
            print('There is always next time!!')
            break
        
        print('HAAAAAAAAAAAAAAAAAAAAAAAAAAAA IMAGINE NOT GETTING THAT RIGHT!!!')
        print('L bozo + ratio')
        guess = input('Try again ')

score = 0
print('Welcome to the animal quiz')
print()
print('In this game you will have to guess the animal')

name = input('What is your name? ')
print('Cool name, I feel like i heard of it before hmmm %s..' % name)
print()
print('Enough stalling onto the game!!!')

guess1 = input('Which bear lives in the north pole ')
check_guess(guess1.strip().lower(), 'polar bear', attempts=3)

你必须把 if attempt == 3 在你的while循环中,因为while循环无限地运行,直到猜测是正确的,所以当 attempt 的值是3,它将什么也不做,因为它仍然在一个循环中,并且没有if语句告诉它值为3后该做什么。

编辑:还将循环条件更改为 still guessing and attempt <= 3

attempt = 0
def check_guess(guess, answer):
    global score
    global name
    global attempt
    still_guessing = True

    while still_guessing and attempt <= 3:
        print(f"attempt {attempt}")
        if attempt == 2:
            print('the correct answer was %s' % answer)
            print('There is always next time!!')
            still_guessing = False
    
        else:
            print('HAAAAAAAAAAAAAAAAAAAAAAAAAAAA IMAGINE NOT GETTING THAT RIGHT!!!')
            print('L bozo + ratio')
            guess = input('Try again ')
            attempt = attempt + 1

        if guess == answer:
            print('Correct wow, i expected worse from someone named     %s' % name)
            if attempt == 0:
                score = score + 3
            elif attempt == 1:
                score = score + 2
            elif attempt == 2:
                score = score + 1
            still_guessing = False
