Arcus | A simple game made in Python using pygame | Game Engine library

I would like to use CSS animations to move an SVG along a linear path across a full-window page with aligning the SVG to this path. Referring to the figure below with the path shown as a red line, I want to specify h in multiples of vh and w in multiples of vw, e.g. h = 30vh, w = 60vw, and calculate the angle α for rotating the SVG shown as the blue triangle.

Or course, this should be responsive and work with different window sizes. I was hoping to do all this in pure CSS.

Following tan(α) = w/h, I can use the arcus tangens function to calculate the angle α from the quotient w/h. Since trigonometric function are not available in CSS yet, I could use a series approximation for calculating the angle as demonstrated here. But the actual show-stopper seems to be the calculation of the quotient w/h as divisions in CSS require the denominator to be unitless. So, 60vw / 30vh is not allowed.

Is there a different way to calculate or set the angle in CSS? Or do I have to fall back to a JavaScript solution here?

Edit: Here is a minimal reproducible example. In order to set the rotation in the first keyframe, the actual angle α would be required. It is currently fixed to rotate(0deg) so the triangle always points upwards instead in the direction of the linear path.

Error explanation and question:

send a file from one server to another and receive a response back. (simple right?) functionally the code is below is working. but instead of a 200 response, the sender gets 500 internal server error with the following stack trace.

Here is sample data I am looking for total buying trade value and total selling trades value based on country.

Here are two tables, country and trades Table [companies]:

Given a company table companylist and a import-export table trades, I want to find the total exports and imports per country. I want to sort them by country name and print 0s instead of nulls if exports/imports are 0. All countries need to be present in output.

We have a SQL database table recording customer comments (ARCMM). I want to extract the most recent comment for each customer. Some customers do not have any comments (i.e. no entries in ARCMM). The most recent comment for a customer will have the most recent date (field DATEENTR) and, for that date, the highest value of field CNTUNIQ. The query below does not work as expected. Best fix?

I'm trying to submit a training script to AzureML (want to use AmlCompute, but I'm starting/testing locally first, for debugging purposes).

The train.py script I have uses a custom package (arcus.ml) and I believe I have specified the right settings and dependencies, but still I get the error:

User program failed with ModuleNotFoundError: No module named 'arcus.ml'

This the python code I have:

I receive an error, from the below statement; It runs perfectly as a select statement, but fails as a delete. Any idea's how to get this statement working as a delete? Seems to error out at C.*
