Question

我有两个名为dictionary.txt file_dictionary和output.txt file_output的文本文件。这两个文件都有三个常用的单词dance，sanct和test但我没有得到任何单词返回比较两个文件：

with open('output.txt') as words_file:
with open('dictionary.txt') as dict_file:
    all_strings = set(map(str.strip, dict_file))
    words = set(map(str.strip, words_file))
    for word in all_strings.intersection(words):
        print(word)

我无法解决问题。请帮助！

Answer 1

Python字符串区分大小写。 output.txt中的字符串是大写字母，因此您需要在进行比较之前将它们转换为小写：

# remove set from this line
words = map(str.strip, words_file)   

# convert list to lower-case, then apply set operation
words = set(map(str.lower, words))

# everything else same as before
for word in all_strings.intersection(words):
       ...

输出：

dance
test
sanct
