Question

对于我的课程作业，我们必须创建一个Python测验，要求用户输入状态的大写字母。他们的视频给了我们答案，但即使输入它，因为他们显示它我不断收到错误，我的程序将无法运行。我的教授要到星期一才开始，我希望有人可以帮助我找到我的错误。我想我要么是拼写错误的单词还是IDK ......我一直盯着它看几个小时，一行一行看起来和给出的例子一样。

感谢您的帮助。

这是我的代码：

# Constant for the number of states to quiz the user on.
NUM_STATES = 5

def main ():
# Initialize the state_caps dictionary.
state_caps = state_cap_dictionary ()

# Initial variables to keep count of the number
# of correct and incorrect answers.
correct = 0
incorrect = 0

#Quiz the user.
for count in range (NUM_STATES) :
     # Get a random entry from the dictionary.
     state, capital = state_caps.popitem ()

#Quiz the user.
print ('What is the capital of ', state, '? ', end=' ')
response = input ()

# Is the user correct?
if response.lower () == capital.lower ():
    correct += 1
    print ('Correct!')
else:
    incorrect += 1
    print ('Incorrect.')

#Display the results                
print ('Correct responses: ', correct)
print ('Incorrect answers: ', incorrect)

这个缩进对我有用：

# Constant for the number of states to quiz the user on.
NUM_STATES = 5

def main():
# Initialize the state_caps dictionary.
     state_caps = state_cap_dictionary()

     # Initial variables to keep count of the number
     # of correct and incorrect answers.
     correct = 0
     incorrect = 0

     #Quiz the user.
     for count in range(NUM_STATES) :
          # Get a random entry from the dictionary.
          state, capital = state_caps.popitem()

          #Quiz the user.
          print('What is the capital of ', state, '? ', end=' ')
          response = input()

          # Is the user correct?
          if response.lower() == capital.lower():
              correct += 1
              print('Correct!')
          else:
              incorrect += 1
              print('Incorrect.')

你错过了一些缩进。此版本适用于Python 3，链接here

你需要记住，函数A使用B，然后两者都需要有相同的缩进，在粘贴的代码中，state_cap_dictionary是main的私有函数，并且你在声明之前使用它。

# Constant for the number of states to quiz the user on.
NUM_STATES = 5

def main ():
    # Initialize the state_caps dictionary.
    state_caps = state_cap_dictionary()

    # Initial variables to keep count of the number
    # of correct and incorrect answers.
    correct = 0
    incorrect = 0

    #Quiz the user.
    for count in range (NUM_STATES) :
         # Get a random entry from the dictionary.
        state, capital = state_caps.popitem()

        #Quiz the user.
        print ('What is the capital of ', state, '? ')
        response = input()

        # Is the user correct?
        if response.lower() == capital.lower():
            correct += 1
            print ('Correct!')
        else:
            incorrect += 1
            print ('Incorrect.')

        #Display the results                
        print ('Correct responses: ', correct)
        print ('Incorrect answers: ', incorrect)


def state_cap_dictionary ():
      sc = { 'Alabama' : 'Montgomery' ,
