Hello,
I'm creating a notepad++ plugin which hosts an embedded python interpreter
by using cffi to build the dll.
So far so good. One obstacle I've found is that I'm not able to use
exec(help(object)) in order to get the wanted info from the object.
The error I get is:

I've already sent this through mail yesterday but it doesn't appear here, maybe
because of the help word in the content. Please execute in case it appears a
second time.

Just saw, that I replied to you directly instead to python list, sorry.
That did it, changed encoding from function to property and now I'm able to

Thank you.

@MRAB, I'm building a notepad++ plugin which can execute the
written code and if one writes help(os) it gets executed via
exec(editor.getText()) and output redirected to the plugin console window.
Sorry to you as well as I have also replied to you directly.
Thank you

In this example the result is the same but the second one
builds, internally, an additional list, therefore isn't as sufficient
as the first one.

Correct, it is little but I'm wondering why this isn't taking into account.
I thought a method called fromhex would imply that bytes for an integer
should be created and as that it would use the proper byte order to create it.

You are correct, but, sorry for not being clear what confused me.
I assumed it would use the sys.byteorder but I guess this is simply a
AssumedError exception. :-)

First thank you for all the answers, very much appreciated.
I assume the root cause might be explained by the zen of python as well.
If the implementation is hard to explain, it's a bad idea.
Maybe I need to rethink my implementation :-)

Hi Crhistian,
hard to tell, what might help is if you can copy/paste code which does
not run (an example should be as small as possible).
In addition, isn't there any output you get when the program doesn't run?

First of all many thanks to everyone for the active participation.
@Chris Angelico
I think I understand what you illustrated with the byte example,
makes sense. As it was developed for 8-bit encoding only,
it cannot be used for mulitbyte encoding.

Hello,
I am subclassing a scintilla window and it happens every now and then
that I get an OverflowError. I've logged the message and could narrow down
that it
is a single windows message which causes this trouble. It's WM_ERASEBKGND.
Now the confusing part for me is the following.
According to MS
def __WndProc(self, hWnd, msg, wParam, lParam):
event_handler = self._event_handler.get(msg, None)
if event_handler:
return event_handler(msg, wParam, lParam)

With python3.7 I'm able to use
_module = importlib.import_module('app.plugins.plugin_dir.plugin_name')
succesfully but with python 3.8 this results in
File "D:\ProgramData\Python\Python38_64\lib\importlib\__init__.py", line 127,
in import_module
return _bootstrap._gcd_import(name[level:]
Seems I've missed that __init__.py's aren't allowed to be empty anymore.
Adding a single # solved the issue.
