如何动态创建包含子目录的目录？

import os

def create_directory(directory_path):
    os.makedirs(directory_path, exist_ok=True)

# 示例：创建名为"parent_dir"的目录，其中包含子目录"child_dir1"和"child_dir2"
parent_dir_path = "/path/to/parent_dir"
create_directory(parent_dir_path)

child_dir1_path = os.path.join(parent_dir_path, "child_dir1")
create_directory(child_dir1_path)

child_dir2_path = os.path.join(parent_dir_path, "child_dir2")
create_directory(child_dir2_path)
