Question

我是python的初学者。我有两个文件。假设文件名是file_1和file_2。现在我想逐行从file_1中获取字符串，并希望在file_2中搜索它。如果在file_2中找到字符串，那么我想打印在file_2中找到的字符串的整行。我想在python中为它编写一个脚本。

这就是我试图做的事情：

    data = open('path//file_2.txt').read()
    for x in open(s.strip() for s in open('path//file_1.txt').readlines()):
           if x in data:
           print(data)
