Remember that dicts can have tuples as keys! Consider a dict with (x,y) keys instead of nested lists for a grid. It simplifies sparse grids, "resizes" are automatic, it doesn't matter where (0,0) is, and you can use negative positions:

@nedbat One thing I learned from Advent of Code is that using complex numbers instead of tuples(e.g. 1+ 2i instead of (1,2) ) has many advantages. Those should work as dict keys too, right? (hashable)

A fair bit of train(s) rides this morning - to get to in
Will grab lunch first and then some walk around. Original plan was to spend a couple of days - perhaps in Shirahama but the cold wasn't too helpful for the beach or camping so just a day trip

@SRDas Where I grew up in Canada, Japanese oranges (“Christmas Oranges”) were a tradition. They came in cardboard boxes, individually wrapped in green tissue paper. Mom always put one in the toe of our Christmas stocking.

    What food do you think has the most intermediate production stages where it is recognizably some other food (not just an ingredient). For example, processed cheese:

    1. Milk
    2. Fresh cheese
    3. Aged cheese
    4. Emulsified cheese

    Boole: invented new logic, possibly accidentally killed by his wife making him sleep in cold wet sheets when he had pneumonia

    Frege: invented new logic, late in life was shattered by a discovery of Russell's, wound up a sad angry anti-semite

    Cantor: invented new logic, everyone hated him, severe depression, conspiracy theories

    Turing; invented new logic, hounded by government, forced to take hormones against his will

    Python 3.12 is out!!

    Download it from python.org

    Some features I'm excited about:

    • Improved ‘Did you mean …’ suggestions for NameError, ImportError, and SyntaxError exceptions 💡
    • asyncio performance improvements ⚡
    • f-strings!! Expression components inside f-strings can now be any valid Python expression

    What's new in Python 3.12:

    I have another Python question. It's kind of a Best Practices question.

    Python Pip has an "extras_require" feature which I interpret as being equivalent to Rust "features". If you pip install packagename[blargarg] you activate the blargarg extra and some additional packages will be installed.

    Imagine a function in a package requires an extra. A user does not install the extra, then calls the function that requires it. What would you expect it to do? Throw an error? Which one?

    @mcc I’m facing this with my library. In order to use it in a PyScript web context, I’d have to remove a requirement for a library that’s not bundled with PyScript but makes the scientific calculations faster. I have both slow and fast private calc functions, and I plan to refactor my library so the user-facing API chooses one based on the “try: import X” result. The user wouldn’t have to change their code if run in different contexts.

    Knowing when to use a set in can be VERY handy sometimes.

    no_neighbors = [
    n
    for n in nums
    if n-1 not in nums
    and n+1 not in nums
    ]

    If "nums" is a list of 500,000 numbers, this takes 54 minutes.

    Convert "nums" to a set and this taken less than 1 second.

    Why?

    It's all about that "in" operator.

    Checking for containment in a list requires looping over the whole list.

    Checking for containment in a set uses the magic of hashing to return an answer without looping.

    freeradical,
    @freeradical@mastodon.online avatar

    @treyhunner I wonder how that would compare to creating two more sets: one { n - 1 for n in n_set} and another for n + 1, and taking their intersection. If n isn’t in that intersection, it has no neighbors.

    @AlSweigart Create abstract base class “lock” with required method led_flash(). In the spirit of YGNI (You’re Gonna Need It), also include methods led_on() and led_off().

    Then, create subclasses “lock_caps” and “lock_num” that inherit from the lock class.

    It's probably time for me to make the switch to Firefox. I was a full time Firefox user back in the day, but as Chrome got mainstreamed I moved to that, and then later to Brave, since I felt like "at least it's not Chrome". But it's hard to even justify that now.

    Thanks for all the birthday wishes! If you want to help celebrate my birthday, you can:

    1. Tell me your favorite thing about my cat Fishy. Yes, I will read all of your comments to him. English is not his first language, but I believe he has a basic understanding of most of the words.
    2. Subscribe to my Patreon so I can continue to write all the dumb silly things that I write.

    I may create Low Quality Facts, but I am very grateful for all of my high quality friends here.
