Audit docs and convert all Web3 instance variables to use w3 name.

[pipermerriam]

What was wrong?

A while back we settled on a convention of using w3 as the variable name for an instance of the Web3 object. We still have some places in the docs that use the old web3 name.

How can it be fixed?

Check through the docs for code examples which use the variable name web3 to represent an instance of the Web3 object and convert them to use w3 instead.

Are there more instances that are looking to be updated @pipermerriam? @aherzfeld suggested "web3 is used as the variable for instances of web3 in many of the .py files" in the previous pull. Would that be good for consistency?

[pipermerriam]

It'd be good to be completely consistent across both .py and documentation to only use w3.

I can take a crack at updating the .py files as well

Hey there, I'm looking to make my first contribution to Web3.py (and first contribution to open-source, in general). Given that the issue is still marked as Open, I was wondering whether there is still something I can help with.

@marcobesier Welcome! Yep, there are still many places in our docs where we us web3 instead of w3. docs/web3.eth.rst is a prime example. Any code examples using web3.eth can move to w3.eth, but if you're doing a find and replace, be sure to not break the doc links (which look like: :attr:'~web3.eth.Eth.default_block').

[marcobesier]

Awesome! Will take a crack at making the update.

@kclowes A quick comment on the pull-request: for now, I just updated the docs/web3.eth.rst file to see if I understood everything correctly. Once you (or someone else) approves the pull request, I would go ahead and update additional doc files in the same manner.

Also, since this is my first real contribution to open-source, please let me know in case I should do anything differently going forward regarding the pull-request submission.

@pipermerriam I am a beginner in open source contribution.

Can you please help me to start with.

Hello, is this issue still active? I am willing to go through the docs and change them.

Sorry, this should have been closed. It was handled in pr #2357
