Question

好的我一直在尝试使用输入Int函数来设置在开始时询问的问题数量，但输入似乎并不想要通过。它可以做对吗？我想要的是能够改变start_test（）值。当用户输入正确的答案时，我希望错误信息在错误后显示正确的答案。

    try_again = input('Would you like to try again? (y/n)').lower()
    if try_again == 'y' or try_again == 'yes':
        start_test(number_questions)

start_test(5)

弄清楚如何将定义的函数的结果放入循环

def prompt_vowel_count(word):
     correct = word_map[word]['vowels']
     ans = input('How many vowels does "{}" contain?'.format(word))
     return check(int(ans), correct)

python 3.5 for循环定义函数放置在循环中
