写一个Python函数让用户输入一个句子

Question

Write a python function to ask the user to input a sentence. If the sentence begins with a vowel, Return the sentence as it is to be printed. If the sentence does not begin with a vowel, Change the first letter to a capital letter and return the sentence to be printed.

This is what I came up with:

sentence = input("Enter a Sentence:")
vowels = ['a', 'e', 'i', 'o', 'u'] 
if: (sentence.find [0]=vowels)    
     print (sentence) 
else: 
     (sentence[0].upper())

Answer 1

You have the right idea but your syntax is incorrect. see below

sentence = input('Enter a Sentence:')
vowels = ['a','e','i','o','u']

if sentence[0] in vowels:
    print(sentence)
else:
    print(sentence.capitalize())
