Sorry for the noob question and thanks in advance.

My piece of code

from m5ui import *
from uiflow import *

import imu


setScreenColor(0x000000)

lcd.setRotation(3)

imu0 = imu.IMU()
label0 = M5TextBox(133, 6, "Text", lcd.FONT_Default,0xFFFFFF, rotate=0)
label1 = M5TextBox(135, 107, "Text", lcd.FONT_Default,0xFFFFFF, rotate=0)
label2 = M5TextBox(131, 182, "Text", lcd.FONT_Default,0xFFFFFF, rotate=0)

R = None
b = None
a = None


def buttonA_wasPressed():
  global R, b, a
  if (-0.5 < imu0.acceleration[0] < 0.5):
    if (0.5 < imu0.acceleration[1] < 1.5):
      lcd.setRotation(1)
  if (-0.5 > imu0.acceleration[0] > -1.5):
    if (0.5 > imu0.acceleration[1] > -0.5):
      lcd.setRotation(2)
  if (-0.5 < imu0.acceleration[0] < 0.5):
    if (-0.5 > imu0.acceleration[1] > -1.5):
      lcd.setRotation(3)
  if (1.5 > imu0.acceleration[0] > 0.5):
    if (-0.5 < imu0.acceleration[1] < 0.5):
      lcd.setRotation(0)
btnA.wasPressed(buttonA_wasPressed)


while True:
  R = imu0.acceleration[0]
  label0.setText(str(R))
  b = imu0.acceleration[1]
  label1.setText(str(b))
  a = imu0.acceleration[2]
  label2.setText(str(a))
  wait(1)
  wait_ms(2)
