QUESTION
I'm writing a callback function in Python:
...ANSWER
Answered 2021-Apr-30 at 01:37Listing [Python.Docs]: ctypes - A foreign function library for Python and [NumPy]: C-Types Foreign Function Interface (numpy.ctypeslib). The latter states about the following 2 items (emphasis is mine):
as_array
Create a numpy array from a ctypes array or POINTER.
ndpointer
An ndpointer instance is used to describe an ndarray in restypes and argtypes specifications. This approach is more flexible than using, for example,
POINTER(c_double), since several restrictions can be specified, which are verified upon calling the ctypes function.
imageBuffer_ptr is not a "ctypes array or POINTER" (literally: it's not a ctypes.POINTER instance, but ctypes.c_void_p one (there's a subtle difference between the 2)).
The C layer (which in our case lies in the middle) doesn't know about NumPy arrays and so on, so from its PoV, that argument is simply an unsigned short* (doesn't have information about shape, ...). So, on it's other side (in the Python callback), you have to reconstruct the array from the plain C pointer. That can be achieved in 2 ways, like I did in the example below:
callback_ct: Use good-old C way: modify the callback's signature to use ct.POINTER(ct.c_ushort). That is the most straightforward, but the drawback is that it loses all the extra checks when called, meaning that it takes any pointer not just a ndarray one
callback_np: Manually recreate the array from the argument (using a series of conversions). It's more advanced (some might even consider it a bit hackish)

QUESTION
Hi I was trying to create a 2D running game so I tried to define two collision functions. One to end the game if I collide with the obstacles and one to increase my score if I collide with the coin. I defined the collision with obstacles as 'collide' and collision with coin as 'special_collide'. The problem I am facing is that 'collide' is working but 'special_collide' isn't. Here is the code :-
...ANSWER

Try this code:
QUESTION
I was programming a game in python using the pygame and math modules. I wrote these codes for doing a collision detection (I made 5 obstacles with which I want my player to collide) but the problem was during playing the game, sometimes it works and sometimes it doesn't.
These are the collision functions I defined
...ANSWER
Answered 2020-Nov-11 at 16:35Right now you only collide if the distance is exactly 27. If you assume spheres, you can still consider them "colliding" if they are less than 27 pixels appart.
So replace all your distances with if distance <= 27: Note the less than or equals.
Another thing to note is that calculating square roots is very slow. It's much faster to check if distance_squared <= 27 * 27 then to check math.pow(distance_squared, 0.5) <= 27.
QUESTION
I am reading a CSV to Pandas DataFrame, counting the rows and then deleting all but the Column names and the first row of data (2 pairs of X,Y geographic coordinates). I subtract one from the other to get Delta_X and Delta_Y. I then want to see if these values are greater or less than Zero (0) so I can work out which Quadrant of a circle they are in. Based on the outcome I will do some calculations.

I want to add title 'Magnitude' on the right side of the y-axis of the histogram. Also want to add scatter plot title inside the frame. How to do that? Can I add these features with one-liner?
my code and output figure is given below
...ANSWER
Answered 2020-Aug-15 at 01:58Rather than a title, just add text to that axis. You can rotate and position it however you like. Here is an example.
QUESTION
Binned_statistic_2d automatically creates bins at the boundaries of each dimension to catch values out of range, making the bin numbers less useful if I am only interested in values within my given range. Is there a way to assign bin numbers to only bins within range?
For example:
...ANSWER
Answered 2020-Aug-06 at 14:59The returned binnumbers form a (nx+2)x(ny+2) grid. The desired restricted binnumbers form a (nx)x(ny) grid.
If we draw x from left to right, and y from bottom to top, we need to subtract:
- two cells for each smaller column (one cell at the top and one at the bottom) (green)
- one complete column of
x's (noting that 2 of these cells have been subtracted in the previous step) (orange) - and, finally, the first cell of the current column (yellow).
This results in the formula (using numpy's broadcasting):
QUESTION
I am trying to put the float result of a calculation into a LineEdit in PyQT5. I know the LineEdit reference is correct as I can change the text to a set value, eg "Test", but I can't setText to display my calculated variable. All the equations etc are working correctly and print to shell, it is just the output to GUI I am struggling with. I need to do the float conversion as the logic refuses to work if I don't. Do I need to convert it back to something else to get it to work with setText? I have put #Default data examples and answers for each stage in the code.
...ANSWER
Answered 2020-Jul-18 at 12:20QLineEdit.setText() expects a string parameter, so you have to convert your float to string first. E.g.:
QUESTION
I have written working code operating via a tkinter gui (so I know the maths etc works) and am trying to convert it to a PyQt5 Gui (importing in the Qt designer .ui file rather than having the code in my 'logic'.py).
The 'print to shell' are only there so I can see the stage causing the failure. It fails at the maths functions. If I remove one, it fails at the next. First fail is:
...ANSWER
Answered 2020-Jul-17 at 17:56I think the problem here is you aren't obtaining the text properly.
It should be Line_Theta = np.radians(float(L_Theta.text())). To access the text inside the QLineEdit you can use the text() property. This will return a QString.

QUESTION
I have a data frame called biny which is an observation of about 9k rows geocoded values, 18 columns. I'm trying to loop through and find the next nearest value, with the items grouped by Precinct. the problem is that the mapping here seems to be sending the rows and columns to map2_dfr, instead of the respective latitude and longitude.
ANSWER
Answered 2020-Jun-30 at 22:26We can use group_split to split by 'PRECINCT', loop over the list with map and then apply the map2
QUESTION
I have a problem mapping the two histogram subplots with different ranges (8.53,9.09) and (9.55,10.83) to one colorbar. But colorbar is drawn using pcolormesh from first or second subplot, and because they don't have overlap the colorbar don't display correct color.
...ANSWER
Answered 2019-Apr-04 at 16:53The following should be a minimal example of the problem with a solution, namely to use the same norm for both plots.

Install Biny
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
