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.
