Re: [Python-ideas] Adding "View Python 3 Documentation" to all Python 2 documentation URLs

[Bar Harel]

A bit radical but do you believe we can contact Google to alter the search
results?
It's for the benefit of the user after all, and many just switch to python
3 in the version picker anyway.

That's a good idea. Could you suggest it to
https://github.com/python/pythondotorg/ ? (There is actually a version
switcher on every page, but it's rather polite. :-)

Another example is PyPI showing a bold "Latest version: x.x.x".
Example: https://pypi.python.org/pypi/requests/2.17.0

Re: [Python-ideas] PEP draft: context variables

why not to call the section 'Running code in the default state' and the
method just `.default_context()`:

with context_vars.default_context():
# here, all context vars start off with their default values
# here, the state is back to what it was before the with block.

Means `clean` here `default` (the variable is constructed as
cvar = ontextvars.Var(default="the default value", ...) ?

Thanks in advance,
