I'm running this python 3 code code:

I use an online music player called "Netease Cloud Music", and I have multiple playlists in my account, they hold thousands of tracks and are very poorly organized and categorized and held duplicate entries, so I want to export them into an SQL table to organize them.

I have found a way to view the playlists without using the client software, that is, clicking the share button on top of the playlist page and then click "copy link".

But opening the link in any browser other than the client, the playlist will be limited to 1000 tracks.

But I have found a way to overcome it, I installed Tampermonkey and then installed this script.

Now I can view full playlists in a browser.

This is a sample playlist.

The playlists look like this:

The first column holds the songtitle, the second column holds the duration, the third column holds the artist, and the last column holds the album.

The text in the first, third and fourth columns are hyperlinks to the song, artist and album pages respectively.

I don't know a thing about html but I managed to get its data structure.

The thing we need is the table located at xpath //table/tbody, each row is a childnode of the table named tr(xpath //table/tbody/tr).

this is a sample row:

I want to rename a list of R Markdowns from a group split. Each dataframe has their own name in the list. My question is that I want to use makeDataReport() to generate a R Markdown report for each group split but the function gives me an error on renaming the new R Markdown output.

I need to resample the rows whose time column is '09:00:00' and '09:30:00' into the row '09:30:00', open takes the value of the open column of '09:00:00' row, low Take the lowest value of the low column of both, high take the highest value of the high column of both, close take the value of the close column of '09:30:00' row, vol take the sum of the vol column of the two, and amount take sum of of both amount columns. Finally delete the '09:00:00' row.

Then loop over code column and date column.

How can I fade out an audio element using vanilla js (no jquery)? I have looked at the numerous other questions on this forum but they all seem overly complicated or use jquery.
