用Python编写一个比较两个文本文件内容是否相同的程序，若所有的段落内容完全相同，显示“compare ok”，否则显示“not equal”，并输出每个文本与另外一个文本不相同的段落内容。

在Python中，你可以使用内置的`open()`函数打开文件，并逐行比较两文件的内容。这里是一个简单的示例，使用`difflib`库来进行比较：

import difflib

def compare_files(file1, file2):
    # 打开并读取文件内容
    with open(file1, 'r') as f1, open(file2, 'r') as f2:
        content1 = f1.readlines()
        content2 = f2.readlines()

    # 使用Differ类进行比较
    d = difflib.Differ()
    diff = list(d.compare(content1, content2))

    # 检查是否有差异
    if not any(line.startswith('+') or line.startswith('-') for line in diff):
        print("compare ok")
    else:
        print("not equal")

        # 获取并打印不相同的段落
        same_lines = [line for line in diff if not (line.startswith('+') or line.startswith('-'))]
        diff_lines = [line for line in diff if line.startswith('+') or line.startswith('-')]
        print("\nDifficult lines:")
        for line in diff_lines:
            print(line.strip())

file1_path = 'file1.txt'
file2_path = 'file2.txt'  # 替换为你需要比较的实际文件名
compare_files(file1_path, file2_path)
