I currently have the following python code that adds a few calculated columns to my consol file. Essentially it combines all the sales files into one combined DF and then adds 4 new sales columns with some conditions back to the consol file. The code works, but it takes about an hour to complete....

I have created a LP function to help maximize a set of features. My first time playing with this library and also conducting LP. Variables: Number of features => X Number of Categories => Y Problem function: Maximize the Z(s) given changes in X and Y. If I add more features (X) from specific ca...

The following Python code is a guessing game in which players have to guess a number between 1 and 10. They only get 3 guesses, and the code will also display if the number is too high or too low, which the player tries to guess. When the while loop exits, because either the number of guessesleft...

This is my first time writing a somewhat non-trivial declarative + recursive macro in Rust. I drew inspiration from this answer. The goal is to come up with a recursive macro that allows to assemble some kind of node tree. The general interface function is something like parent.add_child(child). ...

Problem statement: The \$n\$-by-\$n\$ Hadamard matrix \$H(n)\$ is a boolean matrix with the remarkable property that any two rows differ in exactly \$\frac{\text{n}}{\text{2}}\$ bits. \$H(1)\$ is a \$1\$-by-\$1\$ matrix with the single entry true, and for \$n > 1\$, \$H(2n)\$ is obtained by align...
