Welcome Daniel!
Despite some seeming to think of sending you elsewhere, there are a
number of people 'here' who regularly volunteer their time to help
others.
As with any interaction, the quality of information in the question
directly impacts what can be offered in-response.
More of us can help with (pure) Python questions. Moving into
specialised areas may reduce the number who feel competent to answer.
We'll value any contribution you may be able to offer, and will look
forward to hearing of the projects you attempt...

Thanks. Interesting. I was surprised a Norwegian site would have data for
a small city in the US. I have a Python script that accesses the NOAA (National Oceanic and Atmospheric Administration) API and the data in the Meteogram appears to match well. fwiw, all that does is
observation_url = f"https://api.weather.gov/stations/K{grid_id}/ observations/latest"
response = requests.get(observation_url).json()
using the Python 'requests' package and then parsing out the JSON. Implementing finger probably would be a straight socket connection. I
don't know how useful this is:

I assume gopher is fron the archie, veronica, and jughead days. It appears straightforward.

Python certainly has the tools. You can even construct a web server on a Raspberry Pi Pico but I don't know any specifics about smolnet.

I think it's up to 3.4 in general and erratic past that. It doesn't have
the match from 3.10. I don't think it has f-strings though it may have
the walrus. There are workarounds but it can be annoying.
I haven't worked with CircuitPython lately and don't know if it has pulled
in later features.
- it's cut-down to work on bare-metal which makes for low demands on
resources, but commensurate shortage of the facilities we CPython developers take for-granted (ie may allow ourselves to find annoying)
MicroPython vs CircuitPythonHave you (gentle reader) used both and feel able to offer a comparison
- when to prefer one over the other?

How did this enter the conversation/thread?
Paul's 'contribution' does not even appear on the Archive...
I'm probably guilty. I mentioned in passing the older protocols like
finger could even be implemented on something like the Pico W with MicroPython.
I am confused by the cross-over to Python-list. I only read/post to comp.lang.python. Is that echoed to Python-list or vice versa?

I've only used CircuitPython on the Adafruit Playground Express. https://circuitpython.org/board/circuitplayground_express/
and MicroPython on the Pico W. Since then Adafruit has expanded their collection of boards and support them with CircuitPython.
One difference that makes them hard to compare is the Express has quite a
few on-board sensors like the Arduino Nano Sense 33, and interfaces to
them are baked into CircuitPython.
The Pico W has a wealth of I/O most doubling as I2C, PWM, or A/D with only
a onboard LED for the mandatory 'hello world' blink code. MicroPython is
more generic and you may have to import modules for specific external
devices like the SSD1306 OLED display. That's easily done with Thonny or pipkin.
As far as core Python I'd say they're similar. MicroPython is more generic and may require more work to set up where Adafruit can match the boards
they have developed.
As I said it's been a while but MicroPython has the _threading module so
you can utilize both cores of the RP2040. Adafruit's new Feather has a
RP2040 and like the Pico W assumes you'll be using the PIO to externals rather than anything onboard so CircuitPython probably has it.
https://www.adafruit.com/product/4884
From the horse's mouth:
"There is great C/C++ support, unofficial (but really good) Arduino
support, an official MicroPython port, and a CircuitPython port! We of
course recommend CircuitPython because we think it's the easiest way to
get started and it has support with most of our drivers, displays,
sensors, and more, supported out of the box so you can follow along with
our CircuitPython projects and tutorials."
I don't know if Adafruit has a RP2350 board yet but they say CircuitPython will be even happier on the Pico 2.
https://www.adafruit.com/product/6006
For better or worse there are a lot more choices now than fiddling around with the Arduino Uno back in the day.

This has been happening, without asking our permission, for years.
Adding a display to the Pico-W is my next project... After that, gyros

pipkin is the command line utility. Thonny isn't my favorite IDE but it

You might have to go back a lesson or two for the lead up. As he generally says in the intro most of what he uses is from the Sunfounder Kepler kit.
It has a standard LCD display but he suggested buying the OLED separately
and used it for Lissajous patterns and other fancier stuff.
It's not a bad series although he can be long-winded and his Python style definitely isn't PEP8 friendly.
https://toptechboy.com/
He switched to the Arduino Uno R4 after the IR controller/NeoPixel Pico project and I don't know if he intends to go back to the Pico. He uses
Thonny but I use the MicroPython extension in VS Code. Lately I've been
using Code for everything. Mostly I work on Linux boxes but it's all the
same on Windows. There is a PlatformIO extension that works with Arduino
and other boards. PyLance upsets some because it's a MS product but it
works well too. I've used PyCharm and like it but I also work on C, .NET, Angular, and other projects and Code gives me a uniform IDE.

Typically they are used for I/O with the physical world. Some, like the Arduino Nano Sense, have a number of sensors on the board including a 9
axis inertial, temperature, humidity, barometric, microphone, light intensity, and color sensors. MIT chose this for their TinyML course
because it was one-stop shopping. Using TinyML, a really cut down version
of TensorFlow, gesture, wake word, image recognition, and other tasks were move entirely to the edge device.
Others, like the Pico series, bring out the I/O pins but have little onboard. Many pins are multi-purpose and are used for SPI or I2C
protocols, PWM, A/D measurements, and plain vanilla digital.
The Raspberry Pi series lives in both worlds. Particularly with the new Pi 5, it's usable as a desktop Linux system, if somewhat limited, while bringing out the PIO pins.
It's really a different world than a typical laptop. Years (decades?) ago you could subvert the parallel port controller to provide digital I/O but who has seen a parallel port lately?
There are many families and devices available that are used for any number of projects that need to interact with the real world. The earliest
variants were usually programmed in assembler since 2k of EPROM and 128 bytes of RAM was typical. As they improved C was sued. Now there's enough flash and SRAM to support MicroPython or CircuitPython and they are fast enough for most purposes. There are specialized drivers but if you know Python the bulk of the logic will be very familiar.
For example I have a desktop Python app that pulls weather data from
NOAA's web API. The Pico W has Wifi, so if I wanted to compare NOAA's temperature, humidity, and barometric pressure to the values I read from a local sensor, the API requests and parsing the JSON reply would be almost identical to the desktop code. Conversely I could use the Pico W as a web server to make its sensor reading available.
