os.tmpdir

os.tmpdir(): string

Returns the operating system's default directory for temporary files as a string.

On Windows, the result can be overridden by TEMP and TMP environment variables, and TEMP takes precedence over TMP. If neither is set, it defaults to %SystemRoot%\temp or %windir%\temp.

On non-Windows platforms, TMPDIR, TMP and TEMP environment variables will be checked to override the result of this method, in the described order. If none of them is set, it defaults to /tmp.

Some operating system distributions would either configure TMPDIR (non-Windows) or TEMP and TMP (Windows) by default without additional configurations by the system administrators. The result of os.tmpdir() typically reflects the system preference unless it's explicitly overridden by the users.
