sentence  = []
sentence = input("Please enter a sentence")                        #asks the user to enter a sentence
for i in range(10):                                                #number of words to be searched for
    search = input("please enter a word to be searched for: ")     #asks for a word to be searched for
    letters = sentence.split(' ')#splits the sentence
    correct = False
    for (i, letters) in enumerate(letters):
        if (letters == search):
            print ("your word has been found in position(s): ")    #prints the position of the words
            print (i)
            works = True #the word has been found
            if not True :
                   print("Sorry this word is not in the sentence ")#prints the word cannot be found**

Answer 1

if not True :总是False，你需要“突出”它，因为它使用了错误的间距，所以下面是print语句。

所以if not True :永远不会执行以下操作：

print("Sorry this word is not in the sentence ")

您可能希望将其更改为if not works:，但您没有在任何地方定义works = False，但您确实定义了correct = False，所以也许您在这里混淆了变量的名称。

所以你的代码应该是这样的：

sentence  = []
sentence = input("Please enter a sentence")                        #asks the user to enter a sentence
for i in range(10):                                                #number of words to be searched for
    search = input("please enter a word to be searched for: ")     #asks for a word to be searched for
    letters = sentence.split(' ')#splits the sentence
    correct = False
    for (i, letters) in enumerate(letters):
        if (letters == search):
            print ("your word has been found in position(s): ")    #prints the position of the words
            print (i)
            correct = True #the word has been found
    if not correct :
        print("Sorry this word is not in the sentence ")#prints the word cannot be found**

这应该可行，虽然它可能需要进一步清理，例如：如果你在下一行中输入一个字符串作为输入，为什么要这样做sentence = []。点击此处查看Code Reviews
