The other thing that I just noticed can be a problem is that it is not
clear if a closed pull request is closed because it was merged or
because a better patch was needed (unless the pull was exactly merged,
in which case it says merged at the top). So if you are closing a

The canonicalize() function uses tuple(set()) to try to get a

I saw that sympy did not make it as a mentoring organization for

of Python. Will this change any of the requirements that you mentioned

OK, if it did it correctly, I sent a patch via git with Bernoulli

new types of ODE's that I implement or should
The patch will not be accepted without tests, so yes, the tests should

OK. Is there a way to edit my patch somehow or should I just

Also, are there any guidelines on tests that I should know about?
Just resubmit the patch. You can use

to merge/squash patches. I'll help you with the rest once I can see the patch.
I couldn't figure out how to use that command.
