Coconut VS py-validate

> to be part of the Python ecosystem

I'd rather use Python if I'm in the Python ecosystem. So many attempts were made in the past to make a new language compatible with the Python ecosystem (look up hylang and coconu -- https://github.com/evhub/coconut). But at the end of the day, I'd come back to Python because if there's one thing I've learnt in recent years it's this:

    minimize dependencies at all costs.

Have you had a look at Coconut? I don't know if it'll push all your buttons but whenever I hear someone who's reasonably content with Python but wants more FP goodies I always think of it. https://github.com/evhub/coconut . It's basically a superset of Python3 that transpiles into Python3 and is compatible with MyPy. I don't think I'd code Python w/o it ever again assuming I had the choice. The biggest negative for me is that there's no IDE support for the language last I looked, though of course you can work with the transpiler output (plain Python) in your favorite Python IDE. It might be fun to play around with, I know that I really enjoyed it but then I got spoiled by the language+tooling of Scala3, but if you don't have that option ...

If you're looking for suggestions I want to put forward zig lang if you like C/C++ and Coconut Lang if you like Python!

F# and also the fun, compile-to-Python, functional language called Coconut.

I never had the use case for arbitrary nested input, but I did build a python library that allowed you to specify the HTML input type and the python type to coerce it to + regex validation so that our giant SQL queries would fail at the beginning and not half way thru

I dabbled in generating the HTML forms for calling the scripts, but what I was really excited to do was design a chatbot that would use the type declarations to ask for the scripts' requirements conversationally ("next I need a number for...")

Yes! List/Dictionary/Generator comprehension is one big plus for Python, it probably came from the functional world. I use it whenever I can.

> But even the lambda keyword isn't so bad, you can create a dictionary of expressions to call by name, a lot more compact them declaring them the usual way imo: https://github.com/jazzyjackson/py-validate/blob/master/pyva...

lambda keyword is better than nothing, it definitely can be improved. Just imaging using javascript syntax in your example.

> To your point, I only recently learned there's a Map function in Python, while in JS I'm .map(x=>y).filter(x=>y).reduce(x=>y)ing left and right.

I think with the introduction of list comprehension Guido saw map function was no longer needed, that was why he wanted it removed. I don't deny it, but using map and filter sometimes are just easier to read. Say [foo(v) for v in a] vs map(foo, a).
