如何在两个文本文件中查找单词

2019年8月3日 185次阅读

脚本的第一部分是OK(它删除了http：//和www.).后来我需要检查源内的单词是否存在.

source = open('/net/sign/temp/python_tmp/script1/source.txt','r')
exists = open('/net/sign/temp/python_tmp/script1/exists.txt','r')

with source as f:
        lines = f.read()
        lines = lines.replace('http://','')
        lines = lines.replace('www.','')

        for a in open('/net/sign/temp/python_tmp/script1/exists.txt'):
            if a == lines:
                print("ok")

source.txt的内容：

www.yahoo.it
www.yahoo.com
www.google.com
http://www.libero.it

exists.txt的内容：

www.yahoo.com

最佳答案 这样的事情应该有效：

source_words = set()
with open('source.txt') as source:
    for word in source.readlines():
        source_words.add(word.replace('http://','').replace('www.','').strip())

exist_words = set()
with open('exist.txt') as exist:
    for word in exist.readlines():
        exist_words.add(word.replace('http://','').replace('www.','').strip())

print("There {} words from 'source.txt' in 'exists.txt'".format(
   "are" if exist_words.intersection(source_words) else "aren't"
))

如果您需要获取两个文件中存在的确切单词,则它们位于交集结果中：

print("These words are in both files:")
for word in exist_words.intersection(source_words):
    print(word)
