Question

该程序具有功能，我的问题更多是出于好奇和教育的缘故。如果我已将“ i”定义为“答案”长度范围内的整数，那么如何知道用户的输入是否等于原始字符串？

示例：（＃首次迭代）A，B，C或D？（＃我回答）B （#answers [i] == 1，但是程序知道它也等于B并验证第一个输入是否正确。如果将“ i”定义为整数，它如何知道第一个答案[i]是B？

# List of question answers
answers = ['B', 'D', 'A', 'A', 'C', 'A', 'B', 'A', 'C', 'D']

# List of user responses
response = []

# List of questions answered correctly
correct = []

# Number correctly answered
numCor = 0

# Number incorrectly answered
numIn = 0

# For every question answer, add user-reponse to response list
for i in range(len(answers)):
    question = input('A, B, C, or D: ')
    response.append(question)

    # If the user-response is equal to the question answer /
    # add 1 to correctly answered and add question-number to correct list
    if question == answers[i]:
        numCor += 1
        correct.append(i + 1)

    # If user-response does not match question answer /
    # add 1 to incorrectly answered
    else:
        numIn += 1

# Print correctly/incorrectly answered /
# and question-numbers answered correctly
print('You got', numCor, 'questions correct.')
print('You got', numIn, 'questions incorrect.')
print('Correct Questions:', correct)

Answer 1

answers[i]表示您在answers数组中查找第i个元素，并获得存储在其中的值（以您的情况为字符串）。

如果您是第一次迭代，则i将为0。

answers[0]将为您提供存储在answers的索引0中的值，该值是字符串'B'

如果用户输入B，则您的比较：

if question == answers[i]:

与

相同

if 'B' == 'B':

如果将“ i”定义为整数，那么如何知道是否为question == answers？
