allow human readable key name: get_storage_by_key(storage_key_name)

[drandreaskrueger]

allows

get_storage_by_key(storage_key_name='Sudo Key')

not only

get_storage_by_key(storage_key=0x50a63a871aced22e88ee6466fe5aa5d9)

See ifduyue/python-xxhash#34 (comment) and #3 (comment) (<-- with that please help me! Thanks.)

Included is a python simpletest.py but you probably don't want to merge that.

Hi @drandreaskrueger

Yeah thank you. We won't be merging that.
We are working on a generalized solution for exactly this.
You can find the spec here: https://github.com/w3f/Web3-collaboration/blob/master/grants/speculative/python_substrate_api.md

We hope to finish that by the end of the year.
Therefore, I am closing this PR.

Great news. Looking forward to that.

We hope to finish that by the end of the year.

Nice one. As I want to continue before then ... what is your suggestion what I can do for now? I have other questions too. Which other python libraries exist? Is there a riotchat or slack for substrate+python ? Thanks.

[emielsebastiaan]

Yeah I do not really have a suggestion... hang tight perhaps :)
When it comes to python and substrate we have done all the heavy lifting.
We cannot go any faster than we are already going unfortunately.
That said the stuff we build is actually pretty generalized and should eventually work with any substrate instance regardless of the runtime specification.

If you cannot wait... I suggest you fork the repositories and make modifications downstream.

I can try. Which ones?

If you mean this one, then I have tried already many many things, but I cannot get this beast

py-substrate-interface/substrateinterface/__init__.py

Lines 146 to 147 in 7f64648

	def get_storage(self, block_hash, module, function, params=None, return_scale_type=None, hasher=None,
	spec_version_id='default', metadata=None):

working to simply replicate that example

I would think for one from your team, it would be a quick thing to just write down a Python threeliner example ... how to do the exact same but with your library substrateinterface

That ^ was the purpose of this issue: #3 (comment) <-- please reopen, thanks.

[emielsebastiaan]

I'll ask @arjanz to look at that...

Arjan: if you could look at #3 and see if you have a quick fix for @drandreaskrueger
thx

[drandreaskrueger]

Thanks a lot. Much appreciated!

And again, this is really great news, fantastic. I am loving it already: https://github.com/w3f/Web3-collaboration/blob/master/grants/speculative/python_substrate_api.md#example
