我的代码在elif/else语句中不断显示语法错误

Question

我正试着做一个基本的pig拉丁语翻译，但是编辑一直给我看一个语法错误

ay = "ay"

way = "way"

consonants = ("b", "c", "d", "f", "g", "h", "j", "k", "l", "m", "n", "p", "q", "r", "s", "t", "v", "w", "x", "y", "z")

vowels = ("a", "e", "i", "o", "u")

user_word = input("Enter your word here: ")

first_letter = user_word[0]

first_letter = str(first_letter)

first_letter = first_letter.upper()

if first_letter in consonants:

        print(first_letter + "is a consonant.")

remove_first_letter = user_word[1:]

pig_latin = remove_first_letter + first_letter + ay

print("The word in Pig Latin is " + pig_latin)

elif first_letter in vowels:

        print(first_letter + "is a vowel.")

pig_latin = user_word + way

print("The word in Pig Latin is " + pig_latin)

else:

        print("I don\'t know what" + first_letter + "is.")

这就是我想到的。 它显示的确切错误消息是：

File "<ipython-input-33-8e1536233f19>", line 14

    elif first_letter in vowels:

       ^

SyntaxError: invalid syntax

Python是一种依赖于缩进的语言elif和else需要与if处于相同的深度，并且任何依赖于条件的语句都需要进一步缩进

例如：

if first_letter in consonants:
    print(first_letter + "is a consonant.")
    remove_first_letter = user_word[1:]
    pig_latin = remove_first_letter + first_letter + ay
    print("The word in Pig Latin is " + pig_latin)
elif first_letter in vowels:
    print(first_letter + "is a vowel.")
    pig_latin = user_word + way
    print("The word in Pig Latin is " + pig_latin)
else:
    print("I don\'t know what" + first_letter + "is.")
