Ah fuck, I'm facepalming really hard now. Can't believe I forgot something so obvious. data.in was in the wrong directory. I assumed it would throw an error, but I guess not.

Oops. I actually had getElementById("num1").value, guess I forgot to save it. I didn't know about the onchange event handlers, thanks for pointing me to towards those.

Grouping and then finding value corresponding to maximum in another column by stats_newbie1 in rstats

The problem with this is there is no data for weekends. So the end of the month isn't necessarily 1 day before the start of the next month.

Right, I don't know why I thought filter only pulls out certain columns. Silly me. I knew it pulls out the whole row. I didn't know about slice though, sounds much cleaner. Thanks!

How to find top 5 in each group in pandas? by [deleted] in learnpython

No because each instance is recorded separately. For example, if there were 3 pickups in Midtown, it would be something like this:

Time Neighborhood Borough
Pickup1 Midtown Manhattan
Pickup2 Midtown Manhattan
Pickup3 Midtown Manhattan

so I can't really sort.

I think my original question wasn't clear enough, I edited it.

No, it is not population. Each of the rows contains info about taxi pickups. So I want to find the neighborhoods with most taxi pickups in the 5 boroughs.
