How do I use a whl puython distribution?

[barryjo]

I just downloaded an orbit prediction package called orbit_predictor-1.15.0.py3-none-any.whl.
How do I go about converting this file into python files?

also, when I unpack this distribution, I am sure there are many python methods available. Is there a way to
easily list all of the available methods? Then of course I hope there are descriptions as to what the methods do.

change directory to where wheel has been downloaded
then from terminal window: pip install wheelname

There is no need to download and install wheel(.whl) manually.
When it's on PyPi you do this.

pip install orbit-predictor

Then it download and install all automatic.

I am a bit confused.
I installed ...whl and executed and received the following..

so, where did the files go?? It looks like I should see somewhere??

I am looking to see how to use the downloaded modues and where they are???

In windows python packages are installed in your python distribution. Let's say you installed your Python in c:\Python\Python3.9. Packages installed using pip would appear in: c:\Python\Python39\Lib\site_packages.

There is no need to look at installed files.
Look at orbit-predictor Use example
Type python from command line.
Then look at examples in link over and test that import works.

from orbit_predictor.sources import EtcTLESource
from orbit_predictor.locations import ARG

If you don't get any error when Enter in these line the orbit-predictot packag works.

I found the files where you say.

If I run the following example below I would get an output in x,y,z format. How would I know the units and orientation of the coordinates?
It would be nice if there were some good documentation and better examples.

I would guess that the units are in meters, z is aligned with North, x points to Lat/Long 0/0 and y to 0/90 lat/long????

Of course I would have to calculate local Az/El based on my local Lat/Long and the position vector from SGP4.
Be nice if there were a module to do this.
