Pandas: Feature Request: Include SSPipe Functionality

[jtelleria]

Could pandas include as a submodule "SSPipe" Package?

https://pypi.org/project/sspipe/
https://sspipe.github.io/

DataFrame object already has a .pipe() method, but the objective is to make the "pipe" (Equivalent to R's magrittr %>% functional pipe) a standard that can be extrapolated to all Python objects and casuistics.

So you are basically asking to replicate the behavior of the pipe method with the | operator?

[jtelleria]

Plus a "px" object, which stands as a pipeable object.

In R's magrittr, after using a pipe %>%, objects can be accessed from any argument using a dot (.):

https://cran.r-project.org/web/packages/magrittr/vignettes/magrittr.html

[jtelleria]

You could simply import SSPipe as a submodule as a start :)

And take care of it's maintenance. Fast and easy.

Even if we did want this, we wouldn't be able to since we already use __or__ for elementwise or.

[jtelleria]

Just rename it, I would call such operator %>%, just as R's magrittr pipe.

More familiar for Data Scientist with a R Background.

[TomAugspurger]

You can't define custom operators in Python.

[jtelleria]

Couldn't __or__ function be called %>% or another name?

There must be a solution.

[TomAugspurger]

I don't understand what you're proposing.

[jtelleria]

Add SSPipe as a Pandas submodule:

https://pypi.org/project/sspipe/
https://sspipe.github.io/

And make it work by fixing the issue with __or__ in the submodule internals:

https://github.com/JulienPalard/Pipe/blob/master/pipe.py

https://github.com/sspipe/sspipe/blob/master/sspipe/pipe.py

[WillAyd]

Thanks but I don't think taking over maintenance of another package is something we want to do so closing for now.

[TomAugspurger]

I don't think we'd make that kind of change.

@wesm What do you think about the pipe %>% Topic within Pandas?
