I have a folder consisted of many logs. Each log have a similar format.

This is the log1

I have a dataframe that has multiple tables with 1 or 2 empty rows in between. I want to split based on empty rows.

There are 3 tables here. As you can see, row no. 4,5, 13,14 are blank on which the split must happen.

This is my first stack overflow question, so if I am presenting something wrong, please let me know. I am pretty new to computer programming, so I just have a small webpage where I am just implementing things that I am learning.

I made a little quiz with random trivia multiple choice questions you can take if you press a button. I am using window prompts to ask the questions and get the answers, and I have all of the questions and answers stored as objects with question/prompt and answer pairs. All of those objects are stored in an array in a variable called shortQuizPrompts. I already have the quiz working and everything, aka., It tells you after every question if you got the answer to that question right or wrong, and it gives you a grade afterwards... I also have it set up so that if you enter an answer that is not "a", "b", "c", or "d", it lets you know that it isnt a valid answer. Those sorts of things.

As of right now, you can choose how many questions long you want the quiz to be out of the 24 total questions I have so far. It just asks the questions in the order that they are stored in the array. For example, you will never be asked the last question in the array if you do not choose for the quiz to be the full 24 questions long. However, I want to make the quiz ask the questions in a random order, while also removing those questions from the array as to not ask the same question multiple times.

I have tried increasing the iterator while looping through the array to a random number from 0 to the length of however many questions they chose. Then checking to see if the iterator was larger than the length of the number of questions they chose, it would decrease the iterator until it found a question that is still in the array that it could ask...

If anyone knows how to go about doing that, it would be great. Sorry for the long question btw. I am pretty new to coding, so this is probably a simple answer, but I digress. I'm pretty sure I did everything right. Thx.

[Editing this question completely] Thank you , for those who helped in building the Periodic Table successfully . As I completed it , I tried to link it with another of my project E-Search , which acts like Google and fetches answers , except that it will fetch me the data of the Periodic Table .

But , I got a problem - not with the searching but with the layout . I'm trying to layout the x-scrollbar in my canvas which will display results regarding the search . However , it is not properly done . Can anyone please help ?

Below here is my code :

I would like to make a SPARQL query using MAKG (Microsoft Academic Knowledge Graph) (https://makg.org/) and DBPedia datasets (using SERVICE keyword) on Apache Jena Fuseki.

Before that, I want to test some simpler queries for just MAKG such as:

I have a column in sqlite3 table containing all the chemical elements. There is a column called “Symbol”, where it contains symbols of chemicals. For example, H, Be, Mg.

I would like to pull out all characters from A-Z that does not appear in the column (not case sensitive). Below is what i have currently

Suppose, I want to find the neighboring Hydrogen atoms of a specific C-alpha atom.

Apologies if this has already been asked and answered but I couldn't find a satisfactory answer.

I have a list of thousands of chemical formulas that could include symbols for any element and I would like to determine the total number of atoms of any element in each formula. Examples include:

• CH₃NO₃
• CSe₂
• C₂Cl₂
• C₂Cl₂O₂
• C₂Cl₃F
• C₂H₂BrF₃
• C₂H₂Br₂
• C₂H₃Cl₃Si

I just want the total number of atoms in a single formula, so for the first example (CH₃NO₃), the answer would be 8 (1 carbon + 3 hydrogens + 1 nitrogen + 3 oxygens).

I have found some useful code by PEH (Extract numbers from chemical formula) that uses regular expression to extract the number of instances of a specific element in a chemical formula, and I was wondering if this could be adapted to give the total atoms:
