 On the programming side, you need to import the corresponding class in MicroPython. For the colored light example, you need to import the `ColoredLight` class:
 
-```py
+```python
 from arduino_iot_cloud import ColoredLight
 ```
 
 The cloud variable needs then to be registered with the client using that type and the name that you gave it ("light" in our example):
 
-```py

 client.register(ColoredLight("light", swi=True, on_write=on_colored_light_changed))

 Once you receive these values from the Cloud you will need to convert them to RGB so you can set the RGB LEDs accordingly. For reasons of brevity we won't go into the code for the color conversion, it is provided however in the full example code further down. Also we need to make all three RGB LEDs available in the code so their value can be set:
 
-```py
+```python
 led_red = Pin("LEDR", Pin.OUT)
 led_green = Pin("LEDG", Pin.OUT)
 led_blue = Pin("LEDB", Pin.OUT)
 ```
 
 Then each of the three LEDs' brightness needs to be set so that the resulting color is as desired. This is done using a technique called [PWM](/learn/microcontrollers/analog-output/):
