.. module:: os

:synopsis: basic "operating system" services

|
|
|
The ``os`` module contains functions for filesystem access and ``urandom``.

|
|
|
Pyboard specifics
|
|
-----------------
|
|
|
|
The filesystem on the pyboard has ``/`` as the root directory and the
|
|
available physical drives are accessible from here. They are currently:
|
|
|
|
``/flash`` -- the internal flash filesystem
|
|
|
|
``/sd`` -- the SD card (if it exists)
|
|
|
|
.. only:: port_pyboard
|
|
|
|
On boot up, the current directory is ``/flash`` if no SD card is inserted,
|
|
otherwise it is ``/sd``.
|
|
|
|
.. only:: port_wipy
|
|
|
|
On boot up, the current directory is ``/flash``.
