QUESTION
I am trying to retrieve samples of coordinates in Wikidata via SPARQL but am having a very difficult time trying to achieve it. I would want to get only a single pair of coordinates per place and display the result in a column, and the latitude and longitude of the said coordinates sample in their own columns.
The following code (link to WQS) I use below works, but it does not get the coordinates values labels in Point(5.936111111 51.21)
format. When I replace p:P625
with wdt:P625
, no items are retrieved. Additionally, Borculo (Q1025685) appears twice in the results with two unique coordinates:

for obtaining the coordinates in the desired format (see also the manual on Wikibooks).
Also, it is not sufficient to sample the coordinates statement if you also group by ?lat
and ?long
. Hence, you'd better to sample it in a subquery.
Final result:

I am creating a chess engine with a reset function. I also have a feature where the screen doesn't allow the user to make any more moves after checkmate or stalemate.
However, if i execute my reset function after this, my game stays frozen.
I have two files in my code, my engine and my main. I'm quite sure this is something to do with my main file, however I have put in the engine just in case.
Here they are:

Probably you just need to add it to the r reset handler:

I am making a chess program and I am working on the user UI. One of the things I am working on is the piece animation. I have two files: My chess Engine (irrelevant for this but I have provided just in case) and my main file. Here they are:

Answered 2020-Nov-27 at 21:22You missed to handle the events in the animation loop. See pygame.event.get()
respectively pygame.event.pump()
:
For each frame of your game, you will need to make some sort of call to the event queue. This ensures your program can internally interact with the rest of the operating system.
For instance:
