You can still do that with Python 3. (Although you’ll be better off

ns that at least that many use setuptools;
sometimes with a distutils fallback, but often without one. Moreover,
many of the packages without wheels use setuptools as well.
The sane default choice is entry_points.

And, as eryk sun mentioned, recent Python 2.7 and 3.4 versions ship
setuptools and pip, via the ensurepip module.

cript" vs "console_scripts entry-point"?
Simple: `scripts` are legacy. `entry_points` are the new thing.
There’s also a third approach: gui_scripts entry_points, which work
the same way on Linux/*nix, but on Windows, it means that running your
script by opening the created .exe fi
e akin to shell scripts, using just
entry_points makes stuff harder, because you need to install the code
(and write a setup.py), as opposed to just putting the script
somewhere in $PATH.

No. You need to delete your existing virtualenv and create a new one.
You can just use `pip freeze > requirements.txt` in the old one and
run `pip install -r requirements.txt` in the new one to ”move” all the
packages you had.

nt() with commas adds spaces between all entries, which
might look bad (and it does in this example); the only way to prevent
that is by setting `sep=`, but then you need to remember about a space
after "visited" and around the ampersand…

The correct fix is to exit() from the python3 shell and start it again.
Alternatively, add some main code at the end of your file and use
`python3 hlibert.py`:

1. NEVER use eval().
2. Trying to pass Python code as arguments looks bad. Don’t do that.
3. Your issues with '' are caused by your shell. You would need to
wrap your entire thing in quotes first, or use escaping. But instead,
4. Use argpa
ct and use it — you can
have arbitrary variable names just fine:
things = {}
a = "aabb"
things[a] = []
PS. why are you creating a out of two strings? Why not just a = "aabb"?

Don’t create custom bin/ scripts, use setuptools entry points. I

if/else and just use the same dictionary assignment for both Pythons.
Just be warned that it applies to the entire file and can lead to
problems.
PS. There is no reason to use """multi-line strings""" in this case,
regular "

However, this does not apply in Python 3. Python 3 defaults to
Unicode strings, so you can do:
>>> p = "你好"
and have proper Unicode handling, assuming your system locale is set
