...ANSWER
Answered 2021-Jun-16 at 02:26Convert your dates with to_datetime then subtract from today's normalized date (so that we remove the time part) and get the number of days. Then use pd.cut to group them appropriately.
Anything in the future gets labeled with NaN.
QUESTION
I am trying to use beginMoveColumns to move a single column over in a QTableView, but it doesn't work properly in my example below. The cell selections get shuffled and column widths don't move. Moving rows using the same logic seems to work correctly. What am I doing wrong?
ANSWER
Answered 2021-Jun-15 at 20:13Turns out it was a bug, I made a bug report here: https://bugreports.qt.io/browse/QTBUG-94503
As a workaround I just clear cell selection on column move, and use this snippet to move column widths

How can I paste the data (row and column) passed by the function makeRequest to google sheet.
I am retrieving the data from HTML storing that into an object and passing that object like this makeRequest(facebookAccountData).
I can use something like this below to paste data (row and column) to sheet but in my case user will define which fields he requires. So I want to make this dynamic which I am not able do so.

Answered 2021-Jun-11 at 07:25In your situation, how about the following modification? I thought that when setValues is used instead of appendRow, the process cost will be able to be reduced a little. Ref

I'm trying to parallelize a merge-sort algorithm. What I'm doing is dividing the input array for each thread, then merging the threads results. The way I'm trying to merge the results is something like this:

Ok, but yours is an unnecessarily difficult approach. At each step of the merge process, you want half of your threads to wait for the other half to finish, and the most natural way for one thread to wait for another to finish is to use pthread_join(). If you wanted all of your threads to continue with more work after synchronizing then that would be different, but in this case, those that are not responsible for any more merges have nothing at all left to do.
This is what I've tried:

QUESTION
I have a Spring Boot app with a Kafka Listener implementing the BatchAcknowledgingMessageListener interface. When I receive what should be a single message from the topic, it's actually one message for each line in the original message, and I can't cast the message to a ConsumerRecord.
The code producing the record looks like this:

Answered 2021-Jun-15 at 17:48You are missing the listener type configuration so the default conversion service sees you want a list and splits the string by commas.
QUESTION
I use the following code to update my widget's timeline, but the "result" which I fetched from the core data is not up-to-date.
My logic is when detecting the host app goes to background I call "WidgetCenter.shared.reloadAllTimelines()" and fetch the core data in the "getTimeline" function. After printing out the result, it is old data. Also I fetch the data with the same predicate under the .background, the data is up-to-date.
Also I show the date in the widget view body, when I close the host app, the date is refreshing. Means that the upper refreshing logic works fine. But just always get the old data.
Could someone help me out?
...ANSWER
Answered 2021-Jun-15 at 17:05Update:
I added the following code to refresh the core data before I fetch. Everything work as expect.
QUESTION
I've started to create UI tests for my PyQt5 widgets using QtTest but have run into the following difficulties:
In order to speed up things, some of my widgets only perform operations when visible. As it seems that QtTest runs with invisible widgets, the corresponding tests fail.
For the same reason, I cannot test program logic that makes a subwidget visible under certain conditions.
Is there a way to make widgets visible during test? Is this good practice (e.g. w.r.t. CI test on GitHub) and is QtTest the way to go?
I have tried to use pytest with pytest-qt without success as I couldn't find a proper introduction or tutorial and I do know "Test PyQt GUIs with QTest and unittest".
Below you find a MWE consisting of a widget mwe_qt_widget.MyWidget with a combobox, a pushbutton and a label that gets updated by the other two subwidgets:
ANSWER
Answered 2021-Jun-15 at 17:01The problem is simple: QWidgets are hidden by default so isVisible() will return false, the solution is to invoke the show() method in init() to make it visible:
