Micro:bit - Accelerometer - (Micro python) make microbit count downward movements - only works with gestures

Question

The following code works just fine:

# Add your Python code here. E.g.
from microbit import *

score = 0
display.show(str(score))

   while True:
    if accelerometer.was_gesture('face down'):
        score += 1
        if score < 10:
            display.show(score)
        else: 
            display.scroll(score)
    continue

'''But when I try to replace was_gesture('face down') with get_Z i get an error:'''

# Add your Python code here. E.g.

    from microbit import *

    score = 0
    display.show(str(score))

    z = accelerometer.get_z()

    while True:
        if z < accelerometer.get_z(-500) 
            score += 1
            if score < 10:
                display.show(score)
            else: 
                display.scroll(score)
        continue

I get an error? But why? I just want to get the microbit to count every time I move the device below a certain point?

Answer 1

You've missed a colon at the end of this line:

       if z < accelerometer.get_z(-500) 

Also, the get_z() method doesn't take any arguments: https://microbit-micropython.readthedocs.io/en/latest/accelerometer.html#microbit.accelerometer.get_z
