Answered 2021-May-06 at 12:21subset['AG'].count
is pandas' count
method applied to subset['AG']
. Since it's written without ()
, this gives you the method itself, not any of its results.
What you apparently want to do instead is to access one column of the subset
dataframe. That dataframe has a MultiIndex on its columns, which means that you can access a single column with a tuple of the column names.
So in your code,

I am a newbie in Python, just started to learn. I am doing a sport prediciton based on scores that were before. I have 2 csv files, one is with all matches from the current year and one is filled with standings ( final results of the tournament and rankings + JUST UNIQUE OBJECTS - I mean I only have 14 rows on this). The problem comes with the standings csv that looks like this:

QUESTION
I am using libVLCSharp (Xamarin bindings to the libvlc library) for video playback. I am adding a feature to transcode / compress downloaded videos to the local filesystem. Normally I'd use mobile-ffmpeg for this, but since internally VLC uses ffmpeg with different build configurations, ffmpeg transcoding does not work - android it crashes the app, ios returns a 'Invalid data found when processing input' error message when attempting to convert. The code works fine when libvlcsharp is uninstalled and there is only one instance of the ffmpeg library being used.
So, I'm looking for video compression / transcode options for Xamarin.iOS.
I've looked into the docs for libvlcsharp and it sounds like we can transcode, but it's somewhat vague on how to do that:
https://github.com/videolan/libvlcsharp/blob/3.x/docs/how_do_I_do_X.md
How do I do transcoding? Pretty similarly to how you would do it from the CLI. Read https://wiki.videolan.org/Transcode/ and try media options with Media.AddOption.
In my case, I'd like to transcode non-interactively / in the background of the app. There is a 'dummy' option in the command line interface for doing this, so I was wondering how we'd do this from libvlc / libvlcsharp.
So far, my code from these docs looks like this:
...ANSWER
Answered 2021-Mar-31 at 05:29As replied on the libvlc discord server, when you are transcoding a video, it is not displayed at all and you just don't need to create a VideoView, the MediaPlayer alone is enough. The rest is finding the correct transcoding options, and you already found the correct wiki page for that.
QUESTION
I was wondering, when exception occurs how try with resource statement manages to close resources before entering catch block.
When exception occurs execution immediately jumps to catch block. So where actually try-with-resource closes the resources.
To get better understanding of how it works I decided to see how compiler implements it. I wrote following code and and compiled it.
ANSWER
Answered 2021-Mar-30 at 13:53The behavior of try-with-resources is fully documented in the Java Language Specification, section 14.20.3. try-with-resources.

ANSWER
Answered 2021-Mar-02 at 12:18Your sendMail
does not return a Promise, then await
keyword will not work as your expectation. The function will be finished before the sendMail
process finish.
On the local side, I guess you use serverless-offline
plugin to test your function. Then, the function will not "finished", it just responds -> Different behavior with Lambda environment.
If this.transporter
is an instance of Nodemailler's Transporter, then .sendMail
function is a callback function. You have to convert it to a new function that returns a Promise or just wrap it into a new Promise like this:
