QUESTION
I'm trying to create a visualization based on the data from the Spotify audio analysis. Here is a part of the data:
...ANSWER
Answered 2021-Feb-24 at 10:13One approach is to use d3.bin() to create buckets, and map the buckets to aggregate the properties with an aggregation function, such as d3.median().
The d3.bin() method creates groups of data based on a given bucketing definition (d3 calls it thresholds). The output of d3.bin() is the same data you input, but with arrays around the buckets. For instance, an array [0.2, 0.8, 1.2, 1.8] binned in the thresholds [0, 1, 2] becomes [ [0.2, 0.8], [1.2, 1.8] ].
You can use the d3.bin().value() method to specify an accessor, which in your case is a function that accesses the start property d => d.start.
Since you want the thresholds to be whole seconds, there are a few pre-processing calculations to compute the thresholds; I'll explain them in the comments of the following code snippet:

This file contains information about Ed Sheeran songs. I have gathered the data with the spotify api.

QUESTION
I'm trying to access Spotify's API via the Spotipy library. I'm using a loop to build a dataframe of tracks and audio features for those tracks for the last 50 songs I listened to.
I imagine there are probably way more efficient ways of doing this, but as of now I've got a loop that can add data to an existing dataframe named pddf.
I'm hoping to do this by going row by row and adding columns, because the data added will be dependent on the track uri in that row.
...ANSWER
Answered 2020-Mar-20 at 22:45Just a warning, I'm writing this on the assumption that pddf['track.uri'] and audio_features['uri'] are common columns between the two dataframes. If I'm misunderstanding the structure of your data, you may need to adjust the specific names I'm using in the example.
Okay, so the first problem you may be coming across has less to do with pd.concat() and more to do with the way you're approaching this. If you can, try to generate a DataFrame of the audio features in one go rather than generating a DataFrame in each loop. First, get the list of all of the track uri's that you need to use. Then you can use the loop to make a list of lists (or, even better, a list of tuples). Then, you can turn that into a DataFrame.
For actually turning it into a DataFrame, it's generally better to join them on a common key like the track uri using merge. In this case:
QUESTION
I'm working with Spotify's Spotipy library, and trying to build a pandas dataframe of audio features from Spotify's API.
I'm going about this in what I feel is probably a very inefficient (slow) way, but as of now I've got a dataframe pddf, and I want to access the API to pull audio features for specific tracks using the track's URI (in one of the columns).
As of now, I've got this code...

QUESTION
I'm trying to train a model with a column that contains a serialized list of values. But I'm running into errors with the data's type. What sort of pre-processing do I need to perform before fitting the model?
...ANSWER
Answered 2020-Jan-14 at 19:31You need to split the list into separate columns. Here's a minimal example which explains this idea:
