DOC - Moving Tips and Trick from wiki to Style Guide - added Reading …
This changes referring to https://github.com/pandas-dev/pandas/issues/30964 is for removing tips and tricks section page from the [wiki](https://github.com/pandas-dev/pandas/wiki/Tips-&-Tricks-for-pandas-dev) to the [Code Style guide](https://pandas.io/docs/development/code_style.html). 

Since this is my first contribution, I've tried to keep this as simple as possible. @simonjayhawkins mentioned that the conventions for urlopen and ZipFile should be captured under our contributing style guide, testing section. I've seen that there is no Testing section and have created a new section and added these two sections from the Wiki post here. Enabling the Travis-CI and Azure CI pipeline build seemed a bit tough for me. I will try to do the build from my side in my next PR. 

Let me know if any corrections are needed.


Hi @VijayantSoni - is this still active? If so, can you address Simon's comment? Sorry I somehow missed the comment. I'll add this and update here. @MarcoGorelli Updated the PR with comments. Somehow my local build of the docs got pushed. Is there something I should do in future to avoid this or will the local build be ignored ? 

Also, should I be closing the PR if I don't have any further changes on this or will it be done automatically ?  Thanks for updating, @vijaysaimutyala !

It's generally safer to stage the files you want to commit with `git add <file>` rather than `git add .`, which can end up with you adding a lot more than you intended. Though to be honest I'm not sure how you ended up with those files, I thought they would be in `doc/_build` (which `git` will ignore) - did you follow the instructions [here](https://pandas.pydata.org/pandas-docs/dev/development/contributing.html#how-to-build-the-pandas-documentation)?

If you could remove the extra files, that'd be great.
```
git rm -rf doc/source/_build
git commit -m "<some descriptive commit message>"
git push origin <your branch name>
```
should work, I think.

If the core team is happy with it, they'll merge it in :) Thanks for the clear answers @MarcoGorelli . Honestly I didn't look at the gitignore but was hoping they would be ignored, but they somehow ended up in my commit. I'll be careful from here on.

I'll try out what you've mentioned. Thanks again 🙂 I think we can just delete this wiki entry instead of moving it as its pretty outdated. The second code snippet won't run > I think we can just delete this wiki entry instead of moving it as its pretty outdated.

The content of this PR is not outdated AFAIK, our standard is to use urlopen and ZipFile from pandas.io.common. This PR documents that? Travis CI passed but not updated here. will merge shortly if no objections. Does ZipFile even exist? I didn’t see it there maybe overlooked. Thought we just used stdlib

no it's no longer there. we only have _BytesZipFile now.

@vijaysaimutyala can you remove the ZipFile bit.

@WillAyd OK with urlopen? I think if we maybe add "Lazy-import wrapper for stdlib urlopen, as that imports a big chunk of
    the stdlib." might help? > > Does ZipFile even exist? I didn’t see it there maybe overlooked. Thought we just used stdlib

Sure. Let me know if you want me to add anything else. Thanks @vijaysaimutyala . the CI failures are probably unrelated and fixed on master. can you merge upstream/master to get ci to green to be sure. @simonjayhawkins I merged from upstream and everything looks good. How do I get the CI to run again ?

 @vijaysaimutyala if you just push again, the CI process will restart.

(terminology nitpick, but it looks like you did a rebase instead of a merge, in which case you would need to do a forced push) Done :) Little confused. Thanks @vijaysaimutyala  Thanks to you guys for holding my hand throughout. Though this is a small documentation that might not take much time for you, all of you were patient enough for me to understand and move in a proper direction. I use pandas on a daily basis at work and now I'm proud that I too have put in a little effort. Looking forward for big ones 😁
