在python中逐行比较两个不同的文件

此解决方案一次性读取两个文件，排除空白行，并打印公共行，无论它们在文件中的位置如何：

with open('some_file_1.txt', 'r') as file1:    with open('some_file_2.txt', 'r') as file2:        same = set(file1).intersection(file2)same.discard('n')with open('some_output_file.txt', 'w') as file_out:    for line in same:        file_out.write(line)
