Web app controlling step by step motors

[dnbbrain]

Hi,
I have an basic html page, with an input button that controls 2 step by step motors.
If I input the number 50, the motors will both open at half of course and this is perfect.
How can I make the motors to make 2, or 3, or 4 runs? right now I manage to make them run once.

p = lambda:None
p.__dict__ = json.loads(request.data)
concentration = int(p.concentration)
concentrationSteps = concentration*10
motors.rotate_motor('A', concentrationSteps, 1, 20)
motors.rotate_motor('B', concentrationSteps, 1, 20)
time.sleep(duration)
motors.rotate_motor('A', concentrationSteps, -1, 20)
motors.rotate_motor('B', concentrationSteps, -1, 20)
return "0";

A for loop?

A is the 1st motor, B is the 2nd motor. I was thinking about inputing a number from the keyboard and the motors should execute that number, for example if I enter 5, both the motors should run 5 times, opening and closing

number_of_rotations = int(input("How many rotations? "))
for num in range(number_of_rotations):
    # your current code here

Thank you nilamo, I will post tomorrow updates with this.

No mather were I put

for num in range(number_of_rotations):

it gives IndentationError: expected an indented block.
Can't figure out were how to indent the for?

You don't indent the for statement, you indent the block you're looping over.

still the same IndentationError: expected an indented block.

You most indent code under line 36 and line 44.
My guess.

It was so simple jezz, just used TAB and was ok, so it should do some calculus, if I enter 3 the first motor should do 4.5 runs, clockwise - counter clocwise, and the second motor should do 6.8 runs open - close, instead they run like non stop, like in a loop. Any ideeas? Thank you
