Thanks
...ANSWER
Answered 2021-Apr-07 at 11:36use font awesome icon or material icon or use some other icons to achieve this. Here I used fa icons to achieve this
and slightly modified jquery.
use $(".plusminus > i").removeClass('fa-angle-up').addClass('fa-angle-down'); instead of
$(this).children(".plusminus").text('+');
and use $(this).find(".plusminus > i").removeClass('fa-angle-down').addClass('fa-angle-up'); instead of $(this).children(".plusminus").text('-');

I am trying to get some NBA data. However, I can't seem to be able to select a subset of my data properly. I tried using the subset function to get only the players with more than 10 games but it doesn't work for some reason. It subset works when I use a different column and I don't know why.

I would like to display the 28 buttons below in a 7x4 self-resizing grid. As it stands now, the equal button is being displayed 28 times. I need all 28 different buttons to display in the 7x4 grid. I have all 28 different buttons configured with the row_index and col_index variables, but it's still not working. If you could help steer me in the right direction, I'd greatly appreciate it.

Answered 2021-Mar-11 at 22:49You are placing all of your controls at row=row_index, column=col_index. By the time that runs, row_index is 7 and col_index is 4. You need to hard-code the locations for all of those buttons, as in row_index=0, col_index=3. Then it will work. I'm looking at it now:

QUESTION
I need to define a predicate plusminus(X). that holds of 2 numerals, s(0) which is the successor of 0 meaning s(s(s(0))) = 3 and their negatives p(0) which represents -1 meaning p(p(p(0))) = -3 and can be enumerated such that:
ANSWER
Answered 2021-Jan-02 at 11:52Two problems with your current approach: the first is that you only give plusminus(X) :- negative(X, _). and never plusminus(X) :- negative(X, _).
The predicate negative/2 doesn't take in X and Y and evaluate to true if X = Y-1, it takes in X and Y and evaluates to true if X is nonnegative and X is Y-1.
The second problem is that you need to first unify a variable (in my example below, B), with a value, then force that value to be positive or negative and unify with X.
This worked when I tested it:

First off, sorry for any poor formatting or etiquette, I am new to python and stack overflow. I have seen other somewhat similar questions to this but all others merge the entire list. I only need parts of each dictionary.
I have a list of dictionaries that are ordered in pairs of games (team 1 then team 2) I need to combine a pair of each dictionary into 1 (0+1, 2+3, etc..)
Here is a sample of my complete list of dictionaries for reference
...ANSWER
Answered 2020-Dec-30 at 07:19If you want to work with pairs 0+1, 2+3, etc, then you can use zip() with [0::2] and [1::2]

QUESTION
Basically, I have a table with a bunch of buttons and I've realized that the height stays fixed on multiple screen sizes. Is there a unit for height that is a percentage of the screen size or is there some other way? Here's the XML for the table. So right now, I want the height of the table to be half the screen size it's on. On most pixel devices, it's fine, but for tablets on portrait mode, it's only a 4th of the screen. The height for the table layout rn is wrap content but im fine if u can change it.

Answered 2020-Nov-25 at 16:58There are two common strategies for getting a percentage of the screen (or really, of the parent layout):
