检查两个文件夹内文件是否相同

不多说，直接贴代码

import os

def find_different_files(folder1, folder2):
    # 获取两个文件夹中的所有文件
    files1 = set()
    for root, _, files in os.walk(folder1):
        for file in files:
            relative_path = os.path.relpath(os.path.join(root, file), folder1)
            files1.add(relative_path)

    files2 = set()
    for root, _, files in os.walk(folder2):
        for file in files:
            relative_path = os.path.relpath(os.path.join(root, file), folder2)
            relative_path = relative_path.rsplit('.', 1)[0]
            files2.add(relative_path)

    # 找出不同的文件
    diff_in_1 = files1 - files2
    diff_in_2 = files2 - files1

    return diff_in_1, diff_in_2

# 示例使用
folder1 = 'train'
folder2 = 'val'
diff_in_1, diff_in_2 = find_different_files(folder1, folder2)

print(f"仅存在于 {folder1} 中的文件:")
for file in diff_in_1:
    print(file)

print(f"仅存在于 {folder2} 中的文件:")
for file in diff_in_2:
    print(file)
