virtual.rst example doesn't work

[NiallDarwin]

Copying the example code from virtual.rst (or in the docs here: https://python-can.readthedocs.io/en/master/interfaces/virtual.html) and then running it gives an error on both Spyder and Python2 on a Pi.
I'm an absolute novice on coding, Python & CAN so its probable I've got something wrong. Its disconcerting when examples don't work!

[NiallDarwin]

I have created a working version and (I think) submitted it to be integrated. Let me know if I've done it right or if you don't see it.

Hi @NiallDarwin it sounds like you might be using a version of Python no longer supported by python-can. Have a look at the table on our readme:

If you need more help can you tell us what version of Python and what version of python-can you're using?

[NiallDarwin]

Hi, thanks for the response. My versions are:
On Pi:
Python 2.7.16
Can library 3.3.4

On Spyder 4.1.3 (?) via Anaconda on Windows10:
Python 3.7.7
Can library 3.1.0

Both look like they should be compatible by your list.

Hmm okay sounds like a legit bug, thanks for opening the issue. In the future its a good idea to try include the output that you're seeing, and what you were expecting. For instance if there is an exception that might give us a clue as to what is going on.

You say you've submitted a working version but I don't see any pull requests from you? There is some good documentation from github about how to go about that.

OK, points noted.

I'm not sure what I did the first time but I've now submitted a pull request.

I was expecting the code to run without outputting anything. What I got was:

Spyder Output
runfile('C:/Users/NiallX1/.spyder-py3/untitled0.py', wdir='C:/Users/NiallX1/.spyder-py3')
Traceback (most recent call last):

File "C:\Users\NiallX1.spyder-py3\untitled0.py", line 18, in
assert msg1 == msg2

AssertionError

Thank you so much for creating and maintaining this code. It is greatly appreciated.

Oh, I see you've created a pull request in your own repository - NiallDarwin#1

What you probably meant to do is to create a PR against my "develop" branch develop...NiallDarwin:NiallDarwin-virtualExamplePatch1
then I or one of the many maintainers/contributors to python-can will review your patch and integrate it.

Happy to do it myself, but I like to encourage contributions :-P
