In principle, this is pretty much exactly what the asvs are supposed to represent. ---- You have demonstrated that you are willing to repeat yourself more than I am, to the point that I find pandas interactions more frustrating than fulfilling. I'm going to step away for a little while.

Towards deduplicating APIs and behaviors - level aggregations
by Devin Petersohn Feb. 22, 2021

Feb. 22, 2021

Hi team, I was hoping to open a discussion on deduplicating and ideally simplifying the pandas API. There are multiple cases where certain operations are able to be called many different ways. For concreteness, I propose to start with the `level` parameter to aggregations. In the wild, I do not see a significant number of uses of the `level` parameter for sum/prod/count/etc. Internally, it is simply rewritten as a groupby: https://github.com/pandas-dev/pandas/blob/v1.2.2/pandas/core/generic.py#L10…. My proposal is that the `level` parameter to these aggregations be deprecated in favor of `groupby` with the `level` parameter. To me at least, the `groupby` syntax is more clear about what to expect in terms of output. I am happy to help contribute the changes necessary. I can also open an issue if GitHub is a better place for this discussion. Devin

Hi all, Google has flagged pandas docs as malicious. This is resulting in many messages from Cloudflare and Rackspace to web(a)pydata.org. Anyone know what might have caused this? https://transparencyreport.google.com/safe-browsing/search?url=https:%2F%2F… -- Andy

Crypto project to fund open source
by Marc Garcia Feb. 5, 2021

Feb. 5, 2021

Hi, I've been contacting regarding a crypto project that aims at funding open source projects. Not sure about the details, but seems like if we register pandas, we'll be getting funds as the crypto is mined (after users endorse pandas I think). Not so familiar myself with crypto or the project, but just in case anyone finds it interesting and wants to add pandas to it: https://devprotocol.xyz/ Cheers, Marc
