MicroPython is a full implementation of the Python 3 programming language that runs directly on embedded hardware like Raspberry Pi Pico. You get an interactive prompt (the REPL) to execute commands immediately via USB Serial, and a built-in filesystem. The Pico port of MicroPython includes modules for accessing low-level chip-specific hardware.
|If you’re new to MicroPython, our official guide, "Get started with MicroPython on Raspberry Pi Pico", is a great place to start. Learn the basics of MicroPython and physical computing, connect your Pico to displays and sensors, build alarms, reaction games, and more.|
You can program your Pico by connecting it to a computer via USB, then dragging and dropping a file onto it so we’ve put together a downloadable UF2 file to let you install MicroPython more easily.
Download the correct MicroPython UF2 file for your board:
Then go ahead and:
Push and hold the BOOTSEL button and plug your Pico into the USB port of your Raspberry Pi or other computer. Release the BOOTSEL button after your Pico is connected.
It will mount as a Mass Storage Device called RPI-RP2.
Drag and drop the MicroPython UF2 file onto the RPI-RP2 volume. Your Pico will reboot. You are now running MicroPython.
You can access the REPL via USB Serial.

There is also a book by Raspberry Pi Press available written by Gareth Halfacree and Ben Everard.
In "Get Started with MicroPython on Raspberry Pi Pico", you will learn how to use the beginner-friendly language MicroPython to write programs and connect hardware to make your Raspberry Pi Pico interact with the world around it. Using these skills, you can create your own electro-mechanical projects, whether for fun or to make your life easier.

You can buy the book on the Raspberry Pi Press site.
There is no direct method for software written in MircoPython to discover whether it is running on a Raspberry Pi Pico or a Pico W by looking at the hardware. However, you can tell indirectly by looking to see if network functionality is included in your particular MicroPython firmware:
import network if hasattr(network, "WLAN"): # the board has WLAN capabilities
Alternatively, you can inspect the MicroPython firmware version to check whether it was compiled for Raspberry Pi Pico or for Pico W using the
>>> import sys >> sys.implementation (name='micropython', version=(1, 19, 1), _machine='Raspberry Pi Pico W with RP2040', _mpy=4102)
So if the 'Pico W' string is present and in
sys.implementation._machine that can be used to determine whether your firmware was compiled for Pico W.
