QUESTION
Using pandas, I have created a dataframe that contains the info about weed severity by field. Every field can contain various types of weed. Records are sorted by [field, weed, date] in order to observe the evolution of weed. Ideally, the severity of every weed should be supressed as the time goes by. In order to detect critical items, I would like to compare two consecutive weed severities, grouped by field and weed type and annotate the supression status as the difference between the two observed severities.
Below is the example data

I'm trying to determine the time signature of a midi file in Python using music21. I can obtain the time signature of this sample midi for instance with:
...ANSWER
Answered 2021-Sep-24 at 19:40music21 v.7.1 started making measures in parts parsed from MIDI files. For that reason, the .timeSignature
property is not very useful when called on a Part (example from docs: "This property is not recursive, so a Part will not have the time signature of the measure within it"). The fact that this used to work for MIDI files was inconsistent with the rest of the system.
If you just want the first time signature, perform a recursive search:
Old syntax (still works): myPart.recurse().getElementsByClass(music21.meter.TimeSignature)[0]
New shortcut syntax (v7): myPart[music21.meter.TimeSignature][0]
Equivalently, you can use strings such as 'TimeSignature'
in the getter instead of class names.
You could also index into the first measure and access the .timeSignature
property there: myPart['Measure'][0].timeSignature
.

QUESTION
I am using R to draw a random sample of 24 elements (species) out of a vector containing 36 elements. As I have to repeat this process several times, I would like to create a data frame in which the first column is the name of the species and the second is a counter of the number of times in which the species has been sampled. So, at the end of the first sampling i would have something like:
