Question

我试图创建一个猜谜游戏，用户在字典中选择一个键并猜测它的值。我很难尝试为选择编码变量，以便猜测值。

这是我到目前为止所做的：

def main():
    capitals = {'AL' : 'Montgomery', 'AK' : 'Juneau', 'AZ' : 'Phoenix',
                'AR' : 'Little Rock', 'CA' : 'Sacramento', 'CO' : 'Denver',
                'CT' : 'Hartford', 'FL' : 'Tallahassee', 'GA' : 'Atlanta',
                'HI' : 'Honolulu', 'ID' : 'Boise', 'IL' : 'Springfield',
                'IN' : 'Indianapolis', 'IA' : 'Des Moines', 'KS' : 'Topeka'}
    print("Choose a state from the list", capitals.keys())
    choice = input('Which state would you like to guess? : ')
    choice == capitals.keys()
    guess = input('Guess the capital of the state chosen : ')
    answer = capitals.values()
    if guess == answer:
        print("Yay! You're CORRECT!")
    else:
        print("Sorry, You're INCORRECT!")

main()

我的if语句似乎没有被程序读取。我该如何解决这个问题？

Answer 1

您的语义不正确。在if语句之前，插入

print (guess, answer)

这是基本调试。你会看到问题：answer是所有大写的列表;原始用户输入无法等于整个列表。您只需要与该州的资本进行比较。

你必须对choice进行类似的检查，因为你在那里犯了同样的错误。

提供的代码存在一些问题。这是一个带内联注释的工作版本，用于解释正在发生的事情。 while循环允许您在继续之前检查输入数据。

def main():

    capitals = {'AL': 'Montgomery', 'AK': 'Juneau', 'AZ': 'Phoenix',
                'AR': 'Little Rock', 'CA': 'Sacramento', 'CO': 'Denver',
                'CT': 'Hartford', 'FL': 'Tallahassee', 'GA': 'Atlanta',
                'HI': 'Honolulu', 'ID': 'Boise', 'IL': 'Springfield',
                'IN': 'Indianapolis', 'IA': 'Des Moines', 'KS': 'Topeka'}

    # initialize variables used in while loops
    choice = '' 
    guess = ''

    print("Choose a state from the list: {0}".format(' '.join(capitals.keys())))

    # as long as choice is not in the list of capitals, keep asking
    while choice not in capitals.keys():
        choice = input('Which state would you like to guess? : ')

    # get the correct answer for the chosen state
    answer = capitals[choice]

    # as long as the guess doesn't contain any non-whitespace characters, keep asking
    while guess.strip() == '':
        guess = input('Guess the capital of the state chosen : ')

    # if the cleaned up, case-insensitive guess matches the answer, you win
    if guess.strip().lower() == answer.lower():
        print("Yay! You're CORRECT!")

    # otherwise, you lose
    else:
        print("Sorry, You're INCORRECT!")

main()
