os – 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)
On boot up, the current directory is /flash.
