只打印字符串中的元音 [英] Print only vowels in a string

问题描述

我是 Python 新手，我正在尝试打印字符串中的所有元音.所以如果有人输入嘿，一切都好吗?"，所有元音都需要打印...但我不知道如何?(所以这不是计算元音，而是打印元音)

I am new in Python and I'm trying to print all the vowels in a string. So if someone enters "Hey there, everything alright?" , all vowels needs to be printed...but I don't know how? (so it's not about counting the vowels, its about printing the vowels)

现在我有这个;

sentence = input('Enter your sentence: ' )

if 'a,e,i,o,u' in sentence:
    print(???)

else:
    print("empty")

推荐答案

类似的事情?

sentence = input('Enter your sentence: ' )
for letter in sentence:
    if letter in 'aeiou':
        print(letter)
