Hi Python enthusiasts,
Currently _ssl.c always reports CERTIFICATE_VERIFY_FAILED for any
certification verification errors. In OpenSSL, it's possible to tell from
different reasons that lead to CERTIFICATE_VERIFY_FAILED. For example,
https://expired.badssl.com/ reports X509_V_ERR_CERT_HAS_EXPIRED,

What is to stop you from adding this to micropython as a library
extension? I've never felt the urge to do this and I don't think I've
ever heard it requested before. If you think it should be in the
stdlib, given the timing of the 3.6 feature freeze the earliest time
it could land would be Python

I very much doubt that one assert might depend on another, and if they
do, we can just tell people not to change the debug level. The API to
change this should set __debug__ appropriately.

This idea has come up before. While I can see the use of it, to me at
least that use doesn't feel nearly common enough to warrant dedicated
syntax.
In many cases, it is a "truthy" value you are looking for rather than `is
not None` specifically. That has a convenient spelling:
expr or instead
I'd note you can also save 4 characters by writing:
instead if expr is None else expr

That's what I would like to do, and usually we do just go ahead and
add our own extensions, trying to be Pythonic as possible :)
But we do that a lot and sometimes I think it would be good to discuss
with upstream (ie

I don't think it would look like sys.optimize(flag). At the very least,
it would
There are also peephole optimization.
Removing it may prevent false positives for coverage tool
