helpme | helPME : an efficient library for particle mesh Ewald | GPU library

What I am trying to do is split a character column into multiple columns without losing the additional data in the df and the number of columns is variable depending on the input. I guess it's easier with an example:

This is my controller function to store a product, i have the error in the $validator, i'm using this in the api route, i have the error of the title, i've try so many things and nothing works, please helpme, if i send in $validator the $req->all() it works, but i need to send a picture and thats why i'm using the $productReq, i'm using laravel 8

I have a small piece of code that I need to fix and don't know much about Rust.

When I execute the following, it fail for certains ip values.

I have a Kafka Topic Customer in which I streamed a csv file. Now is it possible to transform the data in kafka based on the
Counts. like if the count is less than 20 send it to topic A and if the counts is greater than 20 send it to topic B
I am new to kafka and i was trying like this but its not working

I am having trouble with JOptionPane. My program is supposed to ask the user a question, if they answer Y is moves on to the next question. But if they answer N it asks another question. My problem is when the user answers with N it just moves on to the Y question. It is basically moving in the order the questions are asked and not following the parameters of the if-else statement. Here is my code:

I have some test code below, that basically makes a user input on the second page with a counter going up as a label, a text input, and a go button. My code just prints out the difference between the number inputted and what the current count is, as long as the number inputted is lower than the label number. Else it will just print "Finished". But when I run the code Kivy pauses and the label doesn't update, but it prints just fine. Do I need to start teaching myself about python threading or is there something I am missing? I want that label to keep updating if I can as the other function runs.

This is a very small version (and useless beyond my learning purposes) of a larger code to read water tank levels. In that code I have a sonar function constantly running the same way I do here, with a clock interval schedule in the build method of the main app. I have labels tied to that level the sonar method returns, but I want to be able to access and do things with that level with user inputs which doesn't just pause the interface every time those buttons to other methods are pressed.

I just want to pull a numerical value from a text input from my Second Class in to my Home Class, then be able to mess around with it in a function. I think I am having trouble grasping the parent-child relationship and syntax here.

Please help...

Python file:

I am trying to have a function run continuously and spit out a distance that the label uses that I'll eventually tie to a sonar module, but the label remains blank and I am at a loss as to what I am doing wrong. If I just add a print statement for that distance variable it prints and updates just fine, just can't get the label to use it.

Part II of my question is how do I reference my same function in the second window and also have a label that updates from that same function?

Thanks for the help in advance, I am very very new to kivy and just started learning python a few months ago as well.
