QUESTION
The goal for my code is to make a rough roadmap using the latitude and longitude of the exits on the pennsylvania turnpike drawing a line between each exit.
I am using a for loop to plot a line on the map every time it loops. This works if i hard code the latitude and longitude but as soon as i plug in my variables nothing gets plotted. Since the coordinates are in order I am just increasing the index every time it loops to get the next coordinates. I have printed the variables inside the loop and verified they have the desired value. I have tried putting the values in ordered pairs but the plot function didn't like me using nparrays. I'm not sure if there is something simple i am missing, but I appreciate any input.
...ANSWER
Answered 2022-Apr-17 at 19:11Okay, based on the discussion above, see below for a solution.
Notes:
- Am using pandas DataFames to easily work with the
.csvfile. thenamesfield is the column names. - Am not using orthographic projection at all.
- Am iterating through the list of highway exits one exit at a time; at each index, am extracting the current and next exits' data - am sure there's a more 'pythonic' way to do this, but this is readable at least.
- edit: the final index in the loop is length-1
QUESTION
I am trying to create an own ttk Theme based on my company's CI. I took the Sun Valley theme as starting point and swapped out graphics, fonts and colors.
However I am stuck on the Label frame. I am trying to position the Label within the frame, kind of like a heading. I.e. there should be some margin between top edge and label, and appropriate top-padding for the content (child widgets).
Now:

Answered 2022-Mar-25 at 04:19It is relatively easy to place ttk.Labelframe text below, on or above the relief graphic. This example uses the text attribute but labelwidget can also be used.
In order for the relief to be visible the background color of Labelframe.Label must be set to "".

I'm trying to categorize the type of jigsaw puzzle pieces (number of heads, if it is a border or a corner...) by analyzing their contours.
The approach I'm trying to follow is analyzing this type of plot (from this paper) that "unwinds" the cartesian coordinates of the contours of the puzzle piece by converting it to polar coordinates; however I'm not able to replicate it.

QUESTION
I wanted to create a model of earth using a global 4k height map that I found online. I found this open source script that can do this.
...ANSWER
Answered 2022-Jan-08 at 22:43When you tell your 2D canvas context to .drawImage(), it's going to draw a 4000 pixels image over a 512 pixels canvas. That's how it's defined in the MDN documents if you only use three img, dx, dy arguments.
You could either:
- Draw the Earth image smaller to fit inside your 512x512 pixels canvas by using the 4th and 5th arguments of
dWidth, dHeight. - Make your canvas larger to match the width and height dimensions of your Earth image.

QUESTION
I have the following Dataframe:
Track FGrating HorseId Last FGrating at Happy Valley Grass Happy Valley grass 97 22609 Happy Valley grass 106 22609 97 Happy Valley grass 104 22609 106 Happy Valley grass 102 22609 104 Happy Valley grass 95 22609 102 Sha Tin grass 108 22609 Sha Tin grass 104 22609 Happy Valley grass 107 22609 95 Sha Tin grass 102 22609 Happy Valley grass 108 22609 107I need to fill the empty cells of the rightmost column according to these two rules:
- If the horse didn't race on the particular track yet (Happy Valley grass, in this example), then the value to be filled is 0;
- Between two races at the particular track (Happy Valley grass, in this example), the value to be filled is the last FGrating on the track in question (the two consecutive rows with Sha Tin grass will get the value 95 and the third one will get 107).
The end result will be like this:
Track FGrating HorseId Last FGrating at Happy Valley Grass Happy Valley grass 97 22609 0 (rule 1) Happy Valley grass 106 22609 97 Happy Valley grass 104 22609 106 Happy Valley grass 102 22609 104 Happy Valley grass 95 22609 102 Sha Tin grass 108 22609 95 (rule 2) Sha Tin grass 104 22609 95 (rule 2) Happy Valley grass 107 22609 95 Sha Tin grass 102 22609 107 (rule 2) Happy Valley grass 108 22609 107I need this for every HorseId on the Dataframe

ANSWER
Answered 2021-Nov-17 at 21:15The problem is that you are not working with the same objects.
When you work with pandas and you get x = pdf.value you actually get Series object. This object can take - in front and it knows that it has to convert the values in it to negative.
But when you work with PySpark and you collect values, you get list object and if you put - in front you get error:
