import os.path error

[66229]

Can you please inform me if the os.path module has been implemented in pybv10-2016-06-18-v1.8.1-65-gcbbd0a.dfu as when I import os.path I receive "ImportError: no module named 'os'.

os.path is not implemented in MicroPython. The module uos contains a sobset of Python's module os. On Pyboard, os is the alias of uos. For Linux MicroPython there exists a micropython-lib (https://github.com/micropython/micropython-lib) with a lot of extensions, including os.path. But that's not portable to PyBoard.

Many thanks for the prompt response...

@66229: Update - a closer look into micropython-lib showed, that there is a os.path implementation, which should be easily portable to Pyboard. It look that only o.path.exists() and os.path.isdir() would have to be adapted, and expanduser() is hardly applicable, but could also modified to return a reasonable value. But that should be possible using the os.stat() call. If you need specific methods, like split(), dirname() or basename(), you can take them from there.

I do not see possibility in MicroPython to check it simple like os.path.isfile
then use this code to solve in alternative way

len([item for item in os.listdir() if fname==item])>0

Code: Select all

len([item for item in os.listdir() if fname==item])>0

Wouldn't it be better to just do:

Code: Select all

fname in os.listdir()
