我有两个文件!!! 我想将 File1.txt 的每一行与 File2 中的所有行进行比较.txt并打印不匹配的行。

我已经尝试了很多 mothods，有时在 for 循环之外使用变量时会遇到问题！ 谁能帮我!!谢谢

解决方案

file_one = open('file1.txt', 'r')
file_two = open('file2.txt', 'r')
content = file_one.readlines()
content_2 = file_two.readlines()
non_match = []
for line in content:
if line not in content_2:
non_match.append(line)
print(('n').join(non_match))
file_one.close()
file_two.close()
