Woodpecker | Simulating the WoodPecker Toy in Jupyter Notebook | Data Visualization library

I've created this example:

I don't know the term of what I am trying to do, so I can't seem to find a similar answer.

I'm trying to make an array that looks like the following:

I'm trying to parse mediawiki markup, specifically the one used in english wiktionary articles.
It not being a programming language, the handling of whitespace and newlines is kind of weird, plus I feel like every step is trial and (lots of) error.

Here's the repo: https://github.com/WorDB/wikitext-parser

The test input file is the pie article: pie.txt
(https://en.wiktionary.org/wiki/pie)

Note: I'm parsing the whole XML dump of wiktionary, so I'd rather find a solution parsing with Antlr and not get suggestions like using some online API.

Table:

I have table of bird observations. This is an example:

I am coding some projects to learn Svelte and I have been trying to make something similar to a spreadsheet where a user type or change numbers and that reactively make some calculus with a predefined formula (the user can not change the formula). I have tried but I can not do it reactively.

For this I have created a component call Spreadsheet that has two props, the data and the columns, similar to how Quasar do it for Tables.

Here is the REPL with the example.

The idea is that a user change the values on the females, males and area columns and that change the value of the density column reactively with poblationDensity formula.

I've been following lessons in Codecademy to learn C++. I've come to the last project where I learned to make a program that works like hangman. I wanted to add a list of words from which the program chooses a new word each time the program is run. (line 5)

What is passed to the function is the birthdate: BirthDate = '02&22&1732';

this is how it is called: "His Native American Totem is the: "" + NATotem(BirthDate) + "".\n";

I have a dataframe in which I would like to determine how many unique bird species each person saw who participated in my "Big Year".

I've tried using a list comprehension and for loops to iterate over each row and determine if it's unique using .is_unique(), but that seems to be the source of much of my distress. I can get a list of all the unique species with .unique(), quite nicely, but I would like to somehow get the people associated with those birds.
