在python中使用mkdir和循环创建目录时出错

import os

def create_directories():
    base_dir = "/path/to/base/directory"
    sub_dirs = ["dir1", "dir2", "dir3"]

    for sub_dir in sub_dirs:
        dir_path = os.path.join(base_dir, sub_dir)
        try:
            os.mkdir(dir_path)
            print(f"Successfully created directory: {dir_path}")
        except FileExistsError:
            print(f"Directory already exists: {dir_path}")
        except PermissionError:
            print(f"Permission denied: {dir_path}")
        except Exception as e:
            print(f"Error occurred while creating directory: {dir_path}")
            print(str(e))

create_directories()
