can i try it?

@seeeturtle
Sure go ahead.
But please leave a comment which API you will work with so that rest of APIs can be implemented by other Contributhon2019 participants.

@coolreader18
Can you assign this issue to @seeeturtle ?
(There may be additional mentees who want to work with)

Sure go ahead.

sure, i'll try to implement Combinatoric iterators.

Hi all, I'll take itertools.accumulate and itertools.tee.

hello, can I try itertools.groupby?

Yep, go ahead!

I am working on itertools.cycle :)

I am working on itertools.compress

What is "taken" and who claimed it. I will try to keep this updated including what gets completed. Please leave a reference to this issue in your PRs to make that easier.

Infinite Iterators

Combinatoric iterators

Hello, Can I try itertools.zip_longest?

No need to ask, just say you're working on it so that others know and don't duplicate work

I'll work on itertools.count()

I’ll work on itertools.chain.from_iterable() then

@dralley , can you remove me from taking combinatoric iterators except product?

@corona10 Are you still working on itertools.cycle()?

@Thrimbda Are you still working on itertools.groupby()?

@Space0726 Are you still working on itertools.zip_longest()?

@Space0726 Are you still working on itertools.zip_longest()?

@dralley Yes, I still working on itertools.zip_longest() and I had finished it once.
It works fine but it was working a bit differently than CPython's itertools.zip_longest(), so I was thinking about it. Should I send a PR first?

@Space0726 Yeah, probably just put a PR up, and maybe the issues can be found during review. If it's got test snippets for the ways in which it isn't working properly, then it won't be merged until it passes the CI anyways.

I'll take cycle and groupby unless someone else wants to (re)claim them. @corona10 @Thrimbda

@dralley Please go a head :)

The last one remaining is itertools.groupby() and it's pretty nasty. I've had it on the backburner for a while and haven't made much progress. If anyone else comes along and wants to tackle it, feel free to do so.

@dralley It might be take some time, but I'll try it.

I'm currently looking at implementing itertools.groupby for #1983.
