Would you expect to use pip in MS Excel? If you type 'python' at a
command line, and get the '>>>' REPL prompt (google REPL), then your
input goes to the python interpreter, which only accepts python
statements. The same is true in the IDLE Shell, and when you run python
code in the editor.
[Some 3rd party IDEs have a front end for PIP. I wanted to add this for
IDLE but the project was vetoed when partly done.]
What one can do in any Python REPL or program is to use subprocess to
call pip. I used something like the following, recently, to prove it
could be done, to install numpy from IDLE shell on Windows.
>>> import subprocess as sub
>>> sub.run("pip install numpy", stdout=sub.PIPE, stderr=sub.STDOUT).stdout
But since I have Command Prompt pinned to the taskbar and often open,
there is no point to this extra typing for me.

I'm back to the proverbial drawing board. On a side note, I'm uninstalling ANACONDA and re-installing. Seems like the whold 400mb of the win executable is missing a bunch of stuff. -- https://mail.python.org/mailman/listinfo/python-list

In my various fits of python downloads, I've managed to download Anaconda, Anaconda is a cpython distribution that comes with various 3rd party modules pre-installed. Pyscripter, I am not familiar with this. IDLE(3.6/32 AND 64bit), IDLE 2.7. If you are on Windows, you did not download 'IDLE'.
