QUESTION
I created a very simple MWE to illustrate my problem. When I type y**(2), the program works. But when I type sin(y) or cos(y), it results in the error TypeError: can't convert expression to float. I discuss attempts to fix this error below.

This is a follow-up to my last post. The code works without any errors and can calculate the next best move. I've been looking into how to incorporate transposition tables and move ordering into my negamax function to make it run faster and more accurately, but it seems somewhat difficult and advanced for a beginner like myself.
You can find my code here.
While researching on the chess programming wiki I found some sample code for transposition tables:
...ANSWER
Answered 2021-Nov-29 at 16:19To use transposition tables you "need" to use Zorbrist hashing. The hashing gives each position an (almost) unique code that you store in the transposition table along with its evaluation. Then, to explain it easily, if the current position you are searching is found in your transposition table you won't have to evaluate it again, you just use the stored value.
Zorbrist keys are a nightmare to get right and very hard to debug. If it helps you can check out my implementation in the Endamat Chess Engine, but since you might have a different approach it might be easier to just read on how Zorbrist keys works and try to get it right for your implementation.

I am new to Flutter.
So I am trying to use Curved animations in flutter but it gives me a type error as mentioned in the title. I have shared my main.dart and welcome_screen.dart below. In documentation https://flutter.dev/docs/development/ui/animations/tutorial they have also used the Animationcontroller and a curve (along with Tween) and I think I have done the same. How to solve this?

QUESTION
I'm pasting the all the code I have been working on for a "strip Chart". I can provide the original code I've taken it from if there is interest. The code works well and generates a chart as expected, but the grid layout is strange. The buttons and label updates are all in awkwardly shaped "spaces". My assumption is the main canvas area takes up a large portion of the frame (window?), so when other widgets are added to the grid they are placed in accordance with the larger canvas window.
Is there a way to either subset the canvas frame/window that is doing the plotting so it doesn't affect the sizes of the other widgets? Or is there a generally better way to place everything together?
Let me know if I need to clarify anything.
Thanks!
EDIT
Here is an image of the GUI. First, the main plotting canvas is in grid(row=1,col=1). When I put the buttons to the right of the figure they are in the same row=1, but now in columns 2 and 3, respectively. Since the row height is so large, the buttons are placed in the center of that row. A similar thing happens with the column width of the buttons when looking at "Ch_A" and "Ch_B" labels.
Ideally, I would like the buttons and the associated "Channel Labels" to be neatly organized around each other. Is there a best practice way to go about this?

I'm new to Python and I am trying to make a function to calculate the sum of triangular numbers between lowerbound and upperbound. However, my output can only return the first triangular number between this 2 limit. Thanks for the help!

QUESTION
I'm trying to write a program to generate a random 3 digit number and reverse it, and so I wrote out two methods where getRandomNum generates the number and reverseDigits reverses it. However the 2nd method doesn't take in the random number generated from the 1st method, as the 1st method shows a 3 digit number but the 2nd method shows 0 when running the code.
I've tried looking up how to share variables between methods and it seems that I need to use static variables outside the methods. But it still shows 0 for reverseDigits.
Am I missing something or is there something else to be done?
...ANSWER
Answered 2021-Sep-20 at 08:58Your methods are void,try something like this by making them return int

- Why is it illegal to put
Because that's just not the syntax.
T is a type variable, the bounds have to be specified where the type variable is declared (within the <> preceding the method return type), not where it is used (in the same way that the type of a variable has to be specified where it is declared, not where it is used, e.g. String foo, not foo.contains("a")).
- Is ... Equivalent?
Not quite.
The advantage of declaring a type variable and using that in the List is that you can then declare variables of that type in the method.
For example:

I am trying to estimate the area of vegetation in square meters on satellite photos, from the colors. I don't have a training dataset, and therefore cannot do machine learning. So I know the results will not be very good, but I try anyway.
To do this, I apply a filter on the colors thanks to cv2.inRange.

Answered 2021-Jul-15 at 16:22Your attempt is pretty close to working! For consecutive points, all you need to do is reset the count if one point doesn't satisfy your condition.
