TIL you can combine two dictionaries with the pipe operator

Exploring generating routes for maps, and I'm gradually whipping together an animation to help me understand BFS better, inspired from @Johnowhitaker visualization in SolveIt lesson 8

A recent UX pattern I've started using, I don't know if I got this from someone else, is I ask AI to allow me to highlight text in an HTML such that the highlight remains and it gets saved to a JSON file so that I can communicate with AI about the things I highlighted. I've found that it makes it a lot easier and quicker for me to get through a lot of text or data during AI-review. I haven't looked at actual numbers, but I would assume it also saves tokens.

idk why, but i find packing everything up into a single line super fun

it's always so cool to get a chance to put the walrus operator := into action 😄

Homogenouity in tensors means every dimension is of the same length. Homogenous: [[1,2],[3,4]] Nonhomogenous: [1,[2,3]]

And back to the triangle

If you have a cooler way, let me know!

To center this, I just have to split the padding onto either side

I can use these methods if I don't want to use whitespace to justify

Salman // 萨尔曼@ForBo7_Oct 12

Turns out, Python has built-in ways to justify text.

I don't have to use the modulo operator. I can pass an argument to the step parameter in range

Salman // 萨尔曼@ForBo7_Oct 12

Observing the output, I see that to have a centered triangle, odd rows can only be output. I can use the modulo operator for this

The next simplest step is printing a right triangle, which involves printing x+1 items

Here's my deduction for printing a centered triangle in Python. Do you know of a cooler way? 🧵/

Repeat 5 times to get a grid

Salman // 萨尔曼@ForBo7_Oct 12

A 5x5 grid has 5 rows so I'll work with rows. The row will have 5 elements.
