比较两个txt.files的内容是否有删除的行或python中的更改

def compare_txt_files(file1, file2):
    with open(file1, 'r') as f1, open(file2, 'r') as f2:
        content1 = f1.read()
        content2 = f2.read()

    lines1 = content1.split('\n')
    lines2 = content2.split('\n')

    deleted_lines = []
    for i, line in enumerate(lines1):
        if line not in lines2:
            deleted_lines.append(i+1)

    if deleted_lines:
        print("以下行已被删除或更改：")
        for line_num in deleted_lines:
            print(line_num)

        return False
    else:
        print("两个txt文件内容相同。")
        return True

# 调用示例
compare_txt_files('file1.txt', 'file2.txt')
