Table A

Table B

Table C

Is there a way to "paste" Table A + Table B into something like Table C?

I've had a website running for almost 20 years, unfortunately I made the mistake of not aligning the HTML character set with the MySql character set, so all of my data seems to be double encoded (I think) or possibly mojibaked, or both. Perhaps one of you experts can clear this up for me.

Before I go on, you should know that I'm intending to upgrade to tomcat 9 HTML5 with UTF8 characters and emojis

I am a beginner programmer looking to improve - I've made some pretty cool Python games with pyGame - and now found an interest in KIVY! The separation of logic and layout is great. But as a non-seasoned veteran in OOP, I am pretty much going crazy at this point. I don't know how to connect all the different parts. Most KIVY tutorials I can follow are basic and concentrate mainly on design - which is fine, but when it comes to putting real meat on the bones, there isn't much to go with.

(Then there are the ones that seemingly build GUI's for the Mars Curiosity rover - those are way over my head). I do grab bits and pieces of knowledge in the process, but my code, and my brain, ends up suffering from too many different approaches and programmer styles colliding together. [hopefully that makes some sense] I wonder if fundamentally I need to start from scratch and throw out bad advice?

In the code below I've set up a simple KIVY gui with two screens. Page one increments a variable "A", page two increments the variable "B". I am able to retrieve and display the values of both variables from each KV 'screen' because they belong to the same root screen-Manager class. But I haven't been able to figure out how to grab and manipulate the same variables in a popup window, since that isn't under the screen-Managers jurisdiction. (Somewhere in some tutorial, I learned to create a popoup in KVlang using the Factory import.) But if I want to set "A" = 0 in a popup, I am stumped. Should I use __init__, global variables, app, App.get_screen, parent/child assert, id,kv properties, bind.

Is resetting "A" & "B" to zero from the popup on either screen something easily accomplished? Am I far off base? How about changing the "B" value from a button on page one, or the "A" value from a button on page two?

I like to plot the time series of my data. However there are some gaps in the date value like in the example below. The following code produces the plot disregarding the missing date. How can I show the missing date i.e. show a gap between 2021-01-02 and 2021-01-04 and similarly 2021-01-06 and 2021-01-08.

I'm working with multiple classes that share some initial common variables/attributes. In order to make it cleaner and avoid calling the same variables multiple times I want to set them all in an initial class (e.g. classA) and then load all this attributes in a classB.

So I would define:

I have this weird Pandas problem, when I use the apply function using values from a data frame, it only gets applied to the first row:

I have a tibble with a number of variables collected over time. A very simplified version of the tibble looks like this.

Is it possible for the code below to be typed correctly?

I'm dealing with a tough question. I need to delete some commas at the end of the line, which is previous some specific strings.
