Question

我必须填写我的在线课程的空白测验，但我似乎陷入困境，而且我很难找到为什么我被卡住了。任何建议都会很棒，谢谢！到目前为止，这是我的代码...当我运行代码时，它会问第一个问题，并且正在寻找答案，但是当我把它放进去时，给我的是＃34;不完全，请再试一次＃34;提示所以我没有正确地回答这个问题吗？

print ('Welcome to my computer programming Quiz, in this quiz you will be 
asked to select from three difficulty levels, easy, medium, and hard. Each 
the level contains 4 - 5 fill in the blank questions')
print ('')
print ('Your score at the end will be based on how many correct answers you 
get compared to the number of guesses you take')
print ('')
# opening introduction to the Quiz

level=None
while level not in ['easy', 'medium', 'hard']:
    level = input ('Please select a difficulty (easy, medium, or hard):').lower() 
    # This is where the difficulty is chosen, this is also is the reason I couldn't get my 
    # code to open until I did some searching around the internet and found that 
    # raw_input had to be replaced with input in newer versions of python. Also, I found 
    # that adding .lower() makes the user's input lower case so that it fits with the 
    # potential answers.

guesses, score = 0, 0 
# this is where the number of guesses and the number of right answers will be collected 
# and then shown to the user at the end

问题似乎非常微不足道。当您使用下面的代码行检查answer中的check_answer是否正确时，

if user_answer == answers:

你answers是一个包含所有答案的array，而user_answer是用户输入的字符串。因此，当您键入第一个答案为＆＃34;命令＆＃34;尝试匹配字符串＆＃34;命令＆＃34;到包含几个字符串的array。绝对不会匹配。

使用以下代码行来解决它：

if user_answer in answers:
