如何检查HDF5路径名是一个组还是一个数据集？

import h5py

def check_object_type(file_path, object_path):
    with h5py.File(file_path, 'r') as file:
        if object_path in file:
            obj = file[object_path]
            if isinstance(obj, h5py.Group):
                print(f"{object_path} is a group.")
            elif isinstance(obj, h5py.Dataset):
                print(f"{object_path} is a dataset.")
            else:
                print(f"{object_path} is neither a group nor a dataset.")
        else:
            print(f"{object_path} does not exist in the file.")

# 示例用法
file_path = 'example.h5'
object_path = '/group1'
check_object_type(file_path, object_path)
