Driving a stepper motor with Micro Python.

An interesting observation is that it is better to connect VC in on the stepper motor to ground rather than 12 Volts or the motor will get warm and waste energy while not in use. The outputs on the H-Bridge will supply 12V when turned on, when they are off they act as ground by default all 4 channels are set to off until your program tells them to change. If you have set your motor power connector to a 12 V supply each then each channel will conduct wasting power.
