QUESTION
I get a string which size is 16 (location of chess pieces on the mini-chess-board). This string may contain only symbols:
- K (king)
- P (pawn)
- N(knight)
- R(rook)
- B(bishop)
- Q (queen)
- and whitespaces (free field).
How can i validate this string with regex to check if string size is really 16, symbols are only of these and also it should necessarily contain one K symbol (because one King should be)
I tried [KQBNRP ]{16} but now cant check for a K symbol
Thank you
...ANSWER
Answered 2020-Jun-01 at 11:57As you know exactly which chars are allowed, you could use a single positive lookahead assertion for a single occurrence of K
Then match any of the listed 16 times using your pattern [KQBNRP ]{16}
QUESTION
Using matlotlib, I can create figures that look like this:
Here, each row consists of a series of numbers from 0 to 0.6. The left hand axis text indicates the maximum value in each row. The bottom axis text represents the column indices.
The code for the actual grid essentially involves this line:

QUESTION
thanks in advance for any help or advice!
I am building a chess application, the frontend is in Reactjs and backend is a server written in Golang using Gorilla mux library. The backend is a chess engine for the human user to play against. The react frontend creates a WebSocket connection with the server in the top-level constructor.
The app works well for a single connection. However, upon opening a second browser tab, the first browser tab's Websocket connection is lost.
The server reports the error,
...ANSWER
Answered 2019-Mar-25 at 08:19The design of your WebServer struct only allows for a single connection.
What happens is that on every initial http request on /uci, the connection get upgaded, and everytime you upgrade the http request to a ws connection, you replace the previous connection on the WebServer struct by that one.
Also, it is not thread safe, as each request is processed in a different goroutine.
I suggest you pass the connection to your UCI method instead of attaching it to the server.
QUESTION
Imagine having a grid with four columns and n rows. Every second element should have a different color than the other. Kind of the basic pattern but only with four columns.
I need this with one single parent which has display: flex on it. I tried to adapt the linked example but I couldn't get it working.
ANSWER
Answered 2018-May-25 at 14:41This is pretty simple, as the pattern is repeated over 2 rows of 4, you just need to apply styles to 8n + i for the chequered pattern:

QUESTION
I have been searching here and on the net. I found somehow close questions/answers to what I want, but still couldn't reach to what I'm looking for.
I have an array of for example, 100 values. The values are in the range from 0 to 100. I want to plot this array as a grid, filling the squares according to the values in the array.
The solutions I found so far are like the followings:
Drawing grid pattern in matplotlib
and
custom matplotlib plot : chess board like table with colored cells
In the examples I mentioned, the ranges of the colors vary and are not fixed.
However, what I am wondering about, is whether I can set the ranges for specific values and colors. For example, if the values are between 10 and 20, let the color of the grid square be red. else if the values are between 20 and 30, let the color be blue. etc.
How this could be achieved in python?
...ANSWER
Answered 2017-May-15 at 03:59You can create a ListedColormap for your custom colors and color BoundaryNorms to threshold the values.
