python-3.x - 如何查找文件中重复的单词？

Question

我的代码遇到一些问题。我试图在文件中查找重复的单词，例如“the the”，然后打印它发生的行。到目前为止，我的代码适用于行数，但给出了整个文件中重复的所有单词，而不仅仅是紧接着的单词。

我需要更改什么才能只计算双倍的单词？

my_file = input("Enter file name: ")
lst = []
count = 1
with open(my_file, "r") as dup:
for line in dup:
    linedata = line.split()
    for word in linedata:
        if word not in lst:
            lst.append(word)
        else:
           print("Found word: {""} on line {}".format(word, count))
           count = count + 1
dup.close()

Answer 1

my_file = input("Enter file name: ")
with open(my_file, "r") as dup:
    for line_num, line in enumerate(dup):
        words_in_line = line.split()
        duplicates = [word for i, word in enumerate(words_in_line[1:]) if words_in_line[i] == word]
        # now you have a list of duplicated words in line in duplicates
        # do whatever you want with it
