.. py:module:: os
MicroPython contains an
os module based upon the
os module in the
Python standard library. It's used for accessing what would traditionally be
termed as operating system dependent functionality. Since there is no operating
system in MicroPython the module provides functions relating to the management
of the simple on-device persistent file system and information about the
To access this module you need to:
We assume you have done this for the examples below.
.. py:function:: listdir() Returns a list of the names of all the files contained within the local persistent on-device file system.
.. py:function:: remove(filename) Removes (deletes) the file named in the argument ``filename``. If the file does not exist an ``OSError`` exception will occur.
.. py:function:: size(filename) Returns the size, in bytes, of the file named in the argument ``filename``. If the file does not exist an ``OSError`` exception will occur.
.. py:function:: uname() Returns information identifying the current operating system. The return value is an object with five attributes: * ``sysname`` - operating system name * ``nodename`` - name of machine on network (implementation-defined) * ``release`` - operating system release * ``version`` - operating system version * ``machine`` - hardware identifier
There is no underlying operating system in MicroPython. As a result the
information returned by the
uname function is mostly useful for
