Python tempfile:坏了还是我做错了？

import tempfile

# 创建临时文件
with tempfile.NamedTemporaryFile() as temp_file:
    # 在这里操作临时文件
    pass

# 创建临时目录
with tempfile.TemporaryDirectory() as temp_dir:
    # 在这里操作临时目录
    pass

import tempfile
import os
import stat

# 创建临时文件并更改权限
with tempfile.NamedTemporaryFile() as temp_file:
    os.chmod(temp_file.name, stat.S_IRUSR | stat.S_IWUSR | stat.S_IRGRP | stat.S_IROTH)
    # 在这里操作临时文件
    pass

# 创建临时目录并更改权限
with tempfile.TemporaryDirectory() as temp_dir:
    os.chmod(temp_dir, stat.S_IRUSR | stat.S_IWUSR | stat.S_IXUSR | stat.S_IRGRP | stat.S_IXGRP | stat.S_IROTH | stat.S_IXOTH)
    # 在这里操作临时目录
    pass
