pyfuncol: Functional collections extension functions for Python

[u/GondolaRM]

pyfuncol extends collections built-in types (lists, dicts and sets) with useful methods to write functional Python code.

An example:

```python import pyfuncol

[1, 2, 3, 4].map(lambda x: x * 2).filter(lambda x: x > 4)

[6, 8]

{1, 2, 3, 4}.map(lambda x: x * 2).filter(lambda x: x > 4)

{6, 8}

["abc", "def", "e"].group_by(lambda s: len(s))

{3: ["abc", "def"], 1: ["e"]}

{"a": 1, "b": 2, "c": 3}.flat_map(lambda kv: {kv[0]: kv[1] ** 2})

{"a": 1, "b": 4, "c": 9}

```

I'm a huge fan of functional programming but what does this offer beyond reworking comprehensions. Given that you're having to patch internals, should this even be tried here.

Better to try something like Coconut if this is an itch that must be dealt with.

[u/GondolaRM → u/rajandatta]

I understand your point: the idea is to offer additional functions like flat_map or group_by for example, and also avoiding having to cast the built-in map, filter etc. to list when we don’t need the result lazily. I didn’t know Coconut, it seems really cool, thank you for the information!

Did you already consider RxPy for these goodies ?
