Interface between Raspberry and Gprdeict

I am working on portable tracker/rotator with Az/El controls using 2 stepper motors and Raspberry Pi B+.
Gpredict installed and hardware established. However I’ve yet to program the device to interpret the data from Gpredict. How do you code the motors in Python to import data from Gpredict and convert it to step angle?

see my response in the other identical post.
