Question

sentence = input("Please enter a sentence:")

words = sentence.split()

position= [0]

myList = [] 

[myList.append(x) for x in words if x not in myList]

a =(" ".join(myList))

print (a)

这段代码允许用户输入一个句子并删除重复的单词。当程序输出句子时，它输出如下句子：

例如，如果我的句子是＆＃39;我喜欢python＆＃39;我的程序会打印出来 I like python到屏幕上

我需要帮助的是我希望程序输出：

['I', 'like', 'python']

请提出任何建议

Answer 1

您只需要在程序中打印myList。

$errors

块引用

Answer 2

这样做：

def removeDuplicates(oldList):
    newList = []
    for i in oldlist:
      if i not in newlist:
        newlist.append(i)
    return newList

并像这样使用它：

sentence = input("Please enter a sentence: ")

words = removeDuplicates(sentence.split())

Answer 3

快速单线。按空格和集合拆分可找到唯一值：

words = list(set(sentence.split(' ')))
print words

Answer 4

不会words产生您想要的结果吗？

In [9]: sentence = input("Please Enter as sentence: ")
Please Enter as sentence: 'I like Python'

In [10]: words = sentence.split()

In [11]: words
Out[11]: ['I', 'like', 'Python']

Answer 5

您可以使用设置命令删除重复项

sentence = input("Please enter a sentence:")
set(sentence.split())

如何在括号中打印这个句子并在每个单词周围加上引号？
