Startup
-------
Upon startup with the ``-s`` option, IDLE will execute the file referenced by
the environment variables :envvar:`IDLESTARTUP` or :envvar:`PYTHONSTARTUP`.
Idle first checks for ``IDLESTARTUP``; if ``IDLESTARTUP`` is present the file
referenced is run. If ``IDLESTARTUP`` is not present, Idle checks for
``PYTHONSTARTUP``. Files referenced by these environment variables are
convenient places to store functions that are used frequently from the Idle
shell, or for executing import statements to import common modules.
In addition, ``Tk`` also loads a startup file if it is present. Note that the
Tk file is loaded unconditionally. This additional file is ``.Idle.py`` and is
looked for in the user's home directory. Statements in this file will be
executed in the Tk namespace, so this file is not useful for importing functions
to be used from Idle's Python shell.
