Not quite.

Recent Pythons include "ensure pip" by default, which is a private 
version of pip which is intended to do nothing but install the latest 
version of pip.

Just because you have installed Python doesn't mean that pip will be 
automatically installed and `pip ...` work from the shell.

There's also the problem that while you can easily install multiple 
versions of Python without them clashing, the same doesn't apply to "pip".

How do you know which version of Python `pip install foo` will use? How 
do I choose the version pip will install into? [not rhetorical questions] 
Don't say "use venv", because using a virtual environment shouldn't be a 
prerequisite for using pip.

How do I deal with permissions errors? [semi-rhetorical question -- I 
know *an* answer, but I don't know if it is the *right* answer]

I keep hearing people say that pip is the greatest thing since sliced 
bread, but my own personal experience with it is that installing pip is 
only half the battle.

If it works for you, great -- but some of us have had so many problems 
getting pip to work that we've gone back to just installing from source.

(Admittedly installing from source is probably harder for Windows users 
than Linux users.)
