python 遞歸比較兩個文件夾

　　以下

import filecmp, os

def compare_folders(folder1, folder2):
    dcmp = filecmp.dircmp(folder1, folder2)
    for name in dcmp.left_only:
        print(f"{folder1}單獨存在的文件: {name}")
    for name in dcmp.right_only:
        print(f"{folder2}單獨存在的文件: {name}")
    for common_file in dcmp.common_files:
        file1_path = f"{folder1}/{common_file}"
        file2_path = f"{folder2}/{common_file}"
        with open(file1_path, 'r') as file1, open(file2_path, 'r') as file2:
            content1 = file1.read()
            content2 = file2.read()
            if content1 != content2:
                fn1 = os.path.join(folder1, common_file)
                fn2 = os.path.join(folder2, common_file)
                print('不同：')
                print(fn1)
                print(fn2)

    # 遞歸比較子文件夾
    for common_dir in dcmp.common_dirs:
        d1 = os.path.join(folder1, common_dir)
        d2 = os.path.join(folder2, common_dir)
        if compare_folders(d1, d2):
            print()

folder1 = "file1"
folder2 = "file2"
compare_folders(folder1, folder2)
