执行join python返回“无”

Question

我的“输出”似乎填充正常但是当我执行连接时，我得到“没有返回。

有什么想法吗？

def englishify_sentence(s):
    """English"""
    words = s.lower()
    words = words.split()# splits sentence into individual words
    output = []

    for i in range(len(words)):
        if words[i].endswith("way"):
            opt1 = words[i][:-3]
            letters = list(opt1)#breaks given word into individual letters
            translate = ("("+opt1+" or "+"w"+opt1+")")
            output.append(translate)
        else:
            opt2 = words[i][:-2]
            opt2_letters = list(opt2)#breaks given word into individual letters
            first_letter = (opt2_letters.pop(-1))
            opt3 = words[i][:-3]
            translate2 = (first_letter+opt3)
            output.append(translate2)
            english = " ".join(output)#removes speech marks and creates a "real" word
    print(output)

english = englishify_sentence("oday ouyay antway anway eggway")
print(english)

Answer 1

您忘记返回该值。

return english

Answer 2

是否打印（输出）给你一个无或打印（英文）？
