first PR. Want to use this to familiarize with the process.

Let me know if there are specific rules for this project.

I followed instruction from development page.

Once this merged, I'll be able to contribute more.

Happy Friday.

Nice, thank you!

Just a few suggestions. Also in components_test.py we also have a test_select. I think we can remove that one, this one is better.

[lp9052]

Thanks Maarten!

I'll remove the test in component test.

And is there any specific reason we prefer Test() over under_test() or test()? As snakecase is the preferred convention. Pep8 will report otherwise.

[lp9052]

urrr. I don't see components_test.py. Can you point out to me where is it?

[maartenbreddels]

I see it is never added to git 🙃
But we use the CamelCase because components are special functions, they are lazy, get re-executed, and contain state, which makes them behave more like classes.

just merged changes and please take a look
