Hi Brett,
The current documentation *cannot* be fixed, since fixing it would entail adding an initial two-page essay on "how to start Python on various platforms/systems" (it is really NOT as simple as Windows=python, Linux=python3) and such a PR will certainly by rejected.
In my opinion, the only alternatives are
1. either harmonize the invocation of python across platforms (and *then* adapt the docs to follow). Which was pretty much the whole topic of this thread so far.
2. or just use "python" consistently across all docs (since that is the *only* command which is at least consistent among python.org installers), and add weasel-wording to "consult documentation of third-party installers"
3. or leave the docs broken for at least some people some of the time.

Hi all,
Related to this text on https://docs.python.org/3/library/venv.html :
============
Note The pyvenv script has been deprecated as of Python 3.6 in favor of using python3 -m venv to help prevent any potential confusion as to which Python interpreter a virtual environment will be based on. ============
It's clearer than the text below to which I originally referred.
However, this text has also problems in that it is too unix-specific. In particular:
- Most seriously, it refers to "python3" which doesn't work with the
python.org Windows installer.
It can, but it's opt-in. It's just one of those things that's easy to forget.
- Less seriously, it refers to "pyenv" as a "script" which is unix jargon
and moreover technically incorrect on Windows. (Also, needlessly specific, it should just be "the pyenv command", how it is implemented is irrelevant for this section).
I disagree with this as Python refers to .Py files that you execute directly as "scripts", so I don't think this requires clarification.
Anyway, a pull request with suggested wording to address your concerns would be the best way to try and rectify the issue.

Hi Antoine,
The venv module is included, however the pyvenv script is in a separate package python3.5-venv .
By the way, I was totally confused by the following text form the
doc.
https://docs.python.org/3/library/venv.html
======== Deprecated since version 3.6: pyvenv was the recommended tool for
creating
virtual environments for Python 3.3 and 3.4, and is deprecated in
Python
3.6.
Changed in version 3.5: The use of venv is now recommended for
creating
virtual environments.
========
Not sure where you're reading that. I'm seeing:
""" Note The pyvenv script has been deprecated as of Python 3.6 in favor of using python3 -m venv to help prevent any potential confusion as to which Python interpreter a virtual environment will be based on. """
I think that's pretty clear. "python3 -m venv env" is the standard and recommended way to spin up a virtual environment.
It's further down in the page, under https://docs.python.org/3/library/venv.html#creating-
virtual-environments
I think the deprecation notice for pyvenv should just be deleted, since it renders like the *module* is deprecated.
Ah, I see it now, thanks.
Agreed; or maybe downgrade it to a parenthetical comment. Focus on "this is how to do the obvious thing", and only as an afterthought mention "it used to be done differently" in case someone greps for pyvenv.
