[Python] Control DC motors in python

I control two DC motors with BTS driver using raspberry. In one file I have this:

def backwardFullSpeedBTS():
rSpeed.ChangeDutyCycle(10)
lSpeed.ChangeDutyCycle(0)

def forwardFullSpeedBTS():
rSpeed.ChangeDutyCycle(0)
lSpeed.ChangeDutyCycle(10)

def stopBTSMotor():
rSpeed.ChangeDutyCycle(0)
lSpeed.ChangeDutyCycle(0)

def start2ndMotor():
rSpeed2.ChangeDutyCycle(80)
lSpeed2.ChangeDutyCycle(0)

def stop2ndMotor():
rSpeed2.ChangeDutyCycle(0)
lSpeed2.ChangeDutyCycle(0)


In the next file I call the previous functions:

from MotorBTS import *

while GPIO.input(gpio_ButtonMStop) != 0:
"""Move arm outward until stop button pressed"""
forwardFullSpeedBTS()
pass
stopBTSMotor() # stops Motor

cTime = float(time.time())
while checkDelay(cTime, 0.5):
start2ndMotor()
pass
stop2ndMotor()


Only it always calls me only the first engine and start2ndMotor never. The problem is that it only imports the first engine, but not the second. I tried splitting the engines into their own files, but it still didn't call the second engine. Do you have any other way to call it or how to solve it?
