如何比较和获取两个路径字符串的差异

import os

def compare_paths(path1, path2):
    # 使用os.path.normpath()函数规范化路径，去除冗余的分隔符和相对路径
    path1 = os.path.normpath(path1)
    path2 = os.path.normpath(path2)

    # 比较两个路径字符串
    diff = os.path.commonprefix([path1, path2])

    # 获取差异部分
    diff1 = path1[len(diff):]
    diff2 = path2[len(diff):]

    return diff1, diff2

# 示例用法
path1 = "/home/user/documents/file.txt"
path2 = "/home/user/pictures/image.jpg"

diff1, diff2 = compare_paths(path1, path2)
print("差异部分1:", diff1)
print("差异部分2:", diff2)

差异部分1: /documents/file.txt
差异部分2: /pictures/image.jpg
