python - python tempfile 在哪里写入文件？

Question

在 python 中，您可以创建一个临时文件，如下所示:

tempfile.TemporaryFile()

然后你就可以写信给它了。 GNU/Linux 系统中写入的文件在哪里？我似乎无法在/tmp 目录或任何其他目录中找到它。

谢谢，

调用 tempfile.gettempdir() function :

Return the directory currently selected to create temporary files in.

您可以通过设置 tempfile.tempdir value 来更改创建临时文件的位置如果你想影响创建临时文件的位置，则到不同的目录。引用文档，如果该值为 None，则规则如下:

If tempdir is unset or None at any call to any of the above functions, Python searches a standard list of directories and sets tempdir to the first one which the calling user can create files in. The list is:

1. The directory named by the TMPDIR environment variable.
2. The directory named by the TEMP environment variable.
3. The directory named by the TMP environment variable.
4. A platform-specific location:
   • On RiscOS, the directory named by the Wimp$ScrapDir environment variable.
   • On Windows, the directories C:\TEMP, C:\TMP, \TEMP, and \TMP, in that order.
   • On all other platforms, the directories /tmp, /var/tmp, and /usr/tmp, in that order.
5. As a last resort, the current working directory.
