suspect number one is that you did not set the python interpreter in Thonny to be the MicroPython (Raspberry Pi Pico). Its under Thonny>Settings on my mac or Tools>Options when I run Thonny from a rpi5. |

Check Thonny on the bottom right corner. There you should see your Pico and which COM-port it uses. Only then Thonny is running your code as micropython with the Pico. |

I checked that first and it says Micropython (Raspberry Pi Pico) - Board
CDC @ COM 3

Ok, strange. Can you show the first few lines of your code, where the import statement is visible? |

Importing machine is in all likelihood the most basic functionality one can imagine. Thonny on the other hand is tool to help the uninitiated with problems they wouldn't have without it. In other words, try without Thonny and all will be well… |

I agree. Thonny is really well designed for beginners and easy to use. But you often encounter problems with it that are unfortunately caused by Thonny and do not occur with other IDEs. And it crashes to often... |

I just opened Thonny to see if there is a problem.
When updated, the board reboots and the command In case there is garbage on your Pico you can download flash_nuke.uf2 first to restart with a virgin Pico |

I tried running a very simple program to flash an LED and it didn't work
when I used " import machine" but when I changed it to"from machine import
Pin " it worked. I made the same change to my original program but it still
didn't work. I am using Thonny but I suspect it's causing the problem so I
am going to try a different IDE. Which one would you suggest?

If I use "import machine" it never gets past that statement.

Could that be your problem?

You mean like that: >>>
MPY: soft reboot
MicroPython v1.26.0 on 2025-08-09; Raspberry Pi Pico2 with RP2350
Type "help()" for more information.
>>> import machine
>>> or that: pyboard.py -c"import machine;print(dir(machine))" |

.The I get just says "MPY: soft reboot". And then if I goto "Visualize

not found or not supported"

Python Tutor doesn't know MicroPython dont' t use it. The simplest way to test this import with Thonny is to click in the "Shell" tab and enter the following at the command line The dir command should display all the functions and classes that are in the machine module. To test a program with Thonny,

It turns out the problem wasn't with Micropython but my lack of
understanding of the limitations of Python Tutor. The error I was getting
was from Python Tutor which doesn't work well with Micropython. Why Thonny
gives the option to use Python Tutor when you are working in Micropython
seems like an error in Thonny.
Thanks to all of the members who sent suggestions to help solve my problem.

Where in Thonny is the option to use 'Python Tutor' ?
I have used Thonny for years (without any problems) and have never seen this option. |

menu Run/Visualize current script at Python Tutor I too never had problem with Thonny and, if not perfect, in my opinion it is quite easy to use for a beginner especially to transfert files from the desktop to the target board. |

Under "Run" → "Visualize current script at Python Tutor", but I've never found the right interpreter setting to make it appear as a usable option. Thonny tends to cause a bit of a kneejerk reaction around here. Because it adds complexity, it's seen as getting in the way of identifying users' issues. So if some people on here see 'Thonny' mentioned, they'll assume that's the user's main problem. I'll admit to finding Thonny generally useful, but I don't use it all the time. I mostly use emacs and mpremote due to familiarity. |

I am using micropython 1.26 on a Raspberry Pico with the Thonny IDE. When I try to run the program it stops on the first line which is" import machine". I get an error message saying machine does not exist or is not supported. I tried updating Micropython in Thonny but with the same results. Then I tried loading Micropython using the uf2 file with the same results. I have tried using both my laptop and my PC with same results. What am I missing?
