Q | blazing fast jit compile javascript css selector

I have this code which prints multiple tables

So I created a poll model in my Django app. I'm going thorugh the polling app tutorial posted on the Django website, however, I'm using a remote MySQL database rather than a SQLite database.

So... I can sympy.integrate a normal distribution with mean and standard deviation:

Given MySQL tables something like this¹:

I have a list (dput() below) that has 4 datasets.I also have a variable called 'u' with 4 characters. I have made a video here which explains what I want and a spreadsheet is here.

The spreadsheet is not exactly how my data looks like but i am using it just as an example. My original list has 4 datasets but the spreadsheet has 3 datasets.

Essentially i have some characters(A,B,C,D) and i want to find the proportions of times each character occurs in each column of 3 groups of datasets.(Check video, its hard to explain by typing it out)

I have the following two interfaces, one which allows a nullable vin, the other that doesn't:

First time actually using anything to do with swing - sorry for the poor code and crude visuals!
Using swing for a massively over-complicated password checker school project, and when I came to loading in a JMenuBar, it doesn't render properly the first time. Once I run through one of the options first, it reloads correctly, but the first time it comes out like this: First render attempt
But after I run one of the methods, either by clicking one of the buttons that I added to check if it was just the JFrame that was broken or using one of the broken menu options, it reloads correctly, but has a little grey bar above where the JMenuBar actually renders: Post-method render

The code for the visuals is as follows:

Once I enter q, I get the error:

I'm having a problem with if statements that I cannot figure out.
