Cross-platform way of getting temp directory in Python


That would be the tempfile module.

It has functions to get the temporary directory, and also has some shortcuts to create temporary files and directories in it, either named or unnamed.

Example:

import tempfileprint tempfile.gettempdir() # prints the current temporary directoryf = tempfile.TemporaryFile()f.write('something on temporaryfile')f.seek(0) # return to beginning of fileprint f.read() # reads data back from the filef.close() # temporary file is automatically deleted here

For completeness, here's how it searches for the temporary directory, according to the documentation:

  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.


This should do what you want:

print tempfile.gettempdir()

For me on my Windows box, I get:

c:\temp

and on my Linux box I get:

/tmp


I use:

from pathlib import Pathimport platformimport tempfiletempdir = Path("/tmp" if platform.system() == "Darwin" else tempfile.gettempdir())

This is because on MacOS, i.e. Darwin, tempfile.gettempdir() and os.getenv('TMPDIR') return a value such as '/var/folders/nj/269977hs0_96bttwj2gs_jhhp48z54/T'; it is one that I do not always want.
