If you need to name the temporary files produced using tempfile, use tempfile.NamedTemporaryFile(). The temporary files and directories created using tempfile are stored in a special system directory for storing temporary files. Python searches a standard list of directories to find one that the...
值得注意的是,临时文件是不能命名的,若需要命名使用 tempfile 生成的临时文件,则需使用 tempfile.NamedTemporaryFile()。 此外,.TemporaryFile() 也是一个上下文管理器,因此它可以与with语句一起使用。 使用上下文管理器会在读取文件后自动关闭和删除文件: ...

执行/path/to/directory/__main__.py中的代码。 运行python /path/to/filename.zip时,Python 会把文件当做一个目录。 换句话说,Python 会做以下两件事: 将【目录】添加到模块路径中。 执行从/path/to/filename.zip中提取的__main__.py中的代码。 Zip 是一种面向端的格式:元数据和指向数据的指针都在末尾。
如果要将文件保存到流中(例如,在使用诸如Pyramid,Flask或Django之类的Web应用程序时),则只需提供NamedTemporaryFile(): >>> from tempfile import NamedTemporaryFile >>> from openpyxl import Workbook >>> wb = Workbook() >>> with NamedTemporaryFile() as tmp: ...
