As a python 'noob' who started seriously playing around with it about a
week ago, I might save you some hassle:

It is really, really much easier to work with guix-managed dependencies;
check out the guix pypi importer to see how this can work.

If you do not want do that, for whichever reason, I can recommend using
a virtualenv. Open a guix environment by issuing:

`guix environment --ad-hoc python-pip python-virtualenv python-numpy 
python-websocket-client python'

Note that it is important that the "python" package comes last in this
invocation!

In the spawned shell, run:

--8<---------------cut here---------------start------------->8---
virtualenv -p python3 my-amazing-venv
source my-amazing-venv/bin/activate
pip3 install python-binance
--8<---------------cut here---------------end--------------->8---

After that, but still in your `guix environment' + `source
my-amazing-venv/bin/activate' shell, you should be able to verify that
you can load up binance:
`python3 -m binance'

It won't complain about not finding the binance module, so in this case,
no output = good news.

Because all of this is a kind of terrible user experience, it might make
sense to string all of this stuff together in a shell script. Again, I'd
like to state that simply getting all of the packages you need packaged
for guix (locally or in guix proper) makes all of this complexity go away.

HTH,
