No way to create slice objects

[halostatue]

I tried to slice a numpy array but this doesn't work since Ruby doesn't understand Python's slice syntax. If I could create a slice object using the Python built-in slice function, I could get around this by passing a slice object to Numpy's getslice method, but afaik there's no way to access this.

Perhaps RubyPython could provide a built-in for this? Access to other Python built-ins would be nice as well, though less necessary. Specifically, access to len and type would be handy.

Yes this would be very useful. I'm able to run the majority of numpy except indexing because of this issue.

One way I can think it might work is by import the function slice from python somehow. Any idea how to do it?

I managed to create one. Here's how:

RubyPython::PyMainClass.send(:new).slice(2, 3)
