Is it possible to two reduce objects into one by summing their properties like so for any generic object

I have to parse lists of names, addresses, etc. that were OCRed and have invalid/incorrect characters in them and on the state postal code I need to recognize the pattern with a 2 character state followed by a 5 digit postal code and replace any non numeric characters in the postal code. I might have OK 7-41.03 at the end of a string I need to remove the hyphen and period. I know that re.sub('[^0-9]+', '', '7-41.03') will remove the desired characters but I need it only replace characters in numbers when found at the end of the string and only if preceded by a two character state wrapped in spaces like OK. It seems if I add anything to the regular expression as far as a lookbehind expression then I can't seem to get the characters replaced. I've come up with the following but I think there must be a simpler expression to accomplish this. Example:

I am trying to reduce lines of code because I realized that I am repeating the same equations every time. I am programming a contour map and putting several sources of intensity into it. Until now I put 3 sources, but in the future I want to put more, and that will increase the lines a lot. So I want to see if it is possible to reduce the lines of "source positions" and "Intensity equations". As you can see the last equation is a logaritmic summation of z1, z2 and z3, is it possible to reduce that, any idea?

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

I have been trying to sort the Column values from A to Z which are populated in the List Box.

I have tried with the following but it does not adjust it. Any help will be appreciated.

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:

I am a beginner learning from a tutorial on how to change the colour of a selected area of a picture with a range of colour options.

I can figure out how to change one area, but unsure how to implement the other areas.

What I want to achieve is to click on the selected area, it highlights the border (CSS), then change the colour by using the colour options.

What is the best way to implement this? I'm I correct in thinking maybe a switch statement with onclick to select the specific area of the picture?

Say I have a list of every single letter in the alphabet
