support for built-in function vars()

[deshipu]

That decorator uses a mechanism called descriptors, which is not implemented in MicroPython for performance reasons. You will have to write your own decorator and make it a little bit less magical.

Function attributes are a seldom used feature of Python - a feature not supported by MicroPython. I suggest replacing the function with a class of the same name having a __call__() method as a workround.

Thanks! we found a way to get around few libraries that were creating issues.

A module example.py looks like:

Code: Select all

class ExampleClass:
	pass

Now, I want to access the name of the class inside the module. In python 2.7, one can do:

Code: Select all

>>> import example
>>> name = 'ExampleClass'
>>> example.__dict__.get(name, None)
<class example.ExampleClass at 0x7f2ed0c492c0>

Any idea how it can be done in micropython?

Use getattr

[amar123deep]

There is no getattr for a module imported in micropython

[deshipu]

Are you sure? Works for me...

Code: Select all

>>> import machine
>>> getattr(machine, 'Pin')
<class 'Pin'>

[amar123deep]

well, I meant user-defined module where a class is declared

[deshipu]

That also works:

Code: Select all

>>> import ssd1306
>>> getattr(ssd1306, 'SSD1306')
<class 'SSD1306'>
