[OSRM-talk] Docker pre-processing from a python script

[Daniel Patterson]

I would recommend reading up on how the `subprocess.run()` function works
in Python.  Based on the error, it looks like you need to do:

subprocess.run(["docker","run","-t","-v", "%s:/data" % os.getcwd(),
"osrm/osrm-backend", "osrm-extract", "-p", "/opt/car.lua",
"/data/berlin-latest.osm.pbf"])

Note how I split the `osrm-extract` parameter into parts in this second
version - that's what the error message is complaining about.  I don't use
python all that often, so YMMV here.
