evhub/coconut

Simple, elegant, Pythonic functional programming.

@mosbasik The real answer is that the interactive tutorial was written by a group of non-core Coconut contributors (which is to say, not me), so I can't really comment on the particular choices that it makes. The non-interactive tutorial was written by me, but it's also pretty old and obviously non-interactive. If you wanted to make some changes to the interactive tutorial, I'd be happy to pull them in and put them up.

cool, thanks for the response. I'll read with an eye to how I might improve things then.

Hey! I tried installing coconut through "pypy3 -mpip install coconut" and, despite the install looking like it went well, "coconut -h" isn't recognized as a command.

I'm an absolute beginner in both pypy3 and coconut, so feel free to correct me.

Juan Castillo

@cfuendesign

Ah, running coconut -h directly from pypy3's scripts folder did the trick.

Evan Hubinger

@evhub

@cfuendesign Yeah, you need to add the scripts folder to your PATH environment variable. See: https://datatofish.com/add-python-to-windows-path/

Alternatively, you can always just do pypy3 -m coconut -h.

Beginner here!

Looking forward to using Coconut but am stumped by something simple.

I'm trying to unpack my parameters (key, value) passed into the map function:

{"A": 1, "B": 2, "C": 3}.items() |*> map$((key, value) -> value) |> list |> print

This works but is "uglier":

{"A": 1, "B": 2, "C": 3}.items() |> map$(key_value -> key_value[1]) |> list |> print

Expected output: [1, 2, 3]

Any help is appreciated :) I'm using Python 3 btw since I know tuple deconstruction changed at one point.

Here's another version using a statement lambda, but also not quite as nice as I'd like:

(
{"A": 1, "B": 2, "C": 3}.items() 
    |> map$(def (key_value) -> key, value = key_value; value) 
    |> list 
    |> print
)

Ivan Cheung

@ivanmkc

I know this would work, but I actually want the parameters to be named and unpacked so I can reference either of them (even though I only use "value" in this example):

{"A": 1, "B": 2, "C": 3}.items() |> map$(-> _[1]) |> list |> print

Evan Hubinger

@evhub

@ivanmkc Here are some options that you might like:

d = {"A": 1, "B": 2, "C": 3}
d.items() |> starmap$((k, v) -> v) |> list |> print
d.items() |> map$(def ((k, v)) -> v) |> list |> print
d.items() |> map$(.[1]) |> list |> print

@ivanmkc

Thanks! This is perfect.

@GianpieroCea Saw your question about data science.

I haven't seen any but I will say that, barring the lack of LSP that keeps me mostly using coconut for prototyping in the notebook, i use coconut constantly for data science. I love what it's done for the maintainability of my code, as well.

So with that, though I've avoided using coconut for codebases that require collaboration (since not many folks can write/read it right away), I would love to start a coconut-for-data-science tutorial.

Been learning/using jupyter book and that could be a great way to do something fast and pretty. let me know if you want to join a repo where we can plan out e.g. key contents and case studies, and I can help adding code based on my irl experience.

same goes for anyone else! :)

I'm trying to setup coconut inside Databricks and came across a bug when trying to use the coconut magics:

TypeError: run_cell() missing 1 required positional argument: 'raw_cell
`

However, looking at the backtrace it is clear that the positional argument was given ipython.run_cell(compiled, shell_futures=False)

Evan Hubinger

@evhub

@pigs:riot.firechicken.net Strange. Can you raise an issue and include the traceback and ipykernel version (also anything else that might help me replicate it)?

Jason O.

@puruzio

I am trying coconut as the kernel_name for Papermill and it complains like this. Is there a way to fix this? coconut3 does show up in jupyter kernelspec list.

No parameter translator functions specified for kernel "coconut3' or language 'coconut'

Evan Hubinger

@evhub

@puruzio Should be fixed if you pip install -U coconut-develop (see #658).

Jason O.

@puruzio

Thank you, but the issue still persists for some reason. Same error message.

Evan Hubinger

@evhub

@puruzio Can you put exactly what you did and what versions you were on in the linked issue?

Jason O.

@puruzio

@evhub Sure. I uninstalled the Coconut 1.6 version, and installed coconut-dev 2.0 using the command you mentioned above.

Jason O.

@puruzio

@evhub Never mind. It's working! I accidentally installed coconut outside of venv.

hello all

I'm very interested in learning coconut, so I was wandering if it works with poetry

Evan Hubinger

@evhub

@dincio:matrix.org should work fine—just compile your coconut to python before you run whatever poetry commands you want to run
