用于比较两个文件并输出差异的Python代码

import difflib

def compare_files(file1, file2):
    with open(file1, 'r') as f1, open(file2, 'r') as f2:
        lines1 = f1.readlines()
        lines2 = f2.readlines()

    diff = difflib.unified_diff(lines1, lines2)

    for line in diff:
        print(line)

# 比较文件1.txt和文件2.txt的差异
compare_files('文件1.txt', '文件2.txt')
