我如何找到所有唯一的单词（没有重复）？

Question

我想查找两个文件中的所有唯一词。我能够列出每个文件中的所有单词，但它给了我重复项。我也想按字母顺序对它们进行排序。我该怎么做？

#!/usr/bin/python3

#First file
file = raw_input("Please enter the name of the first file: ")

store = open(file)

new = store.read()

#Second file
file2 = raw_input("Please enter the name of the second file: ")

store2 = open(file2)

new2 = store2.read()

for line in new.split():
    if line in new2:
            print line

Answer 1

这里有一个可能对你有帮助的 sn-p：

new = 'this is a bunch of words'
new2 = 'this is another bunch of words'

unique_words = set(new.split())
unique_words.update(new2.split())
sorted_unique_words = sorted(list(unique_words))
print('\n'.join(sorted_unique_words))

更新：

如果您只对两个文件共有的单词感兴趣，请改为这样做：

unique_words = set(new.split())
unique_words2 = set(new2.split())
common_words = set.intersection(unique_words, unique_words2)
print('\n'.join(sorted(common_words)))
