Another thing worth mentining is that you can define your own custom formatting rules for your classes by implementing the ___format___ method.

It's import to realise that you don't just use f-strings for printing, sometimes they are great for converting data from one format to another. If you use the bin() function to convert a number (n) into a binary string, it adds a '0b' prefix, which you may then need to remove using slicing. You could just use f'n:b' to do the same thing, or for example, if you use f'n:032b' you get a 32-bit binary string with all the leading zeroes included! Much simpler than writing some code to do the same thing.

Very useful. Those IC.enanle and disable were amazing for verbose functions and argparse. Tysm

Great tutorial as usual - very useful tips for formatting.

Awesome!!! Very useful. Thanx a lot

Nice! 2:16

great to know this stuff. thank you.

Great! Are you planning to make a second edition of the Python Bible book? It's been 2 years since the first edition published, can't wait for continuation!

Everytime I have a question about python I end up at your channel. Your videos are very informative and great to learn from! PS: How is the song called in your intro?

Hello there! In 11:10, I'd like to do something like this: day = 7 month = 6 year = 2023 MAX_DAYS = 31 MAX_MONTHS = 12 print(f"{day:len(MAX_DAYS)}.{month:len(MAX_MONTHS)}.{year}") Also, if we wanted to have the binary in 11:40 like 0100_1001 etc and not 100_1001 etc. Like add the last 0 when cutting it in bits of 4 or 8, how could we do that?

thank you, py mentor.

what key stroke did he use at 10:13 to delete every in the format string?

Very useful :-)

when you did dollar values how did it know to separate after 3 digits? Is that default behavior?

_amazing_

Hey, when will you talk about the real company Cannafarm Ltd that brings profit?

Why dont you use python 3.11?

Do Little work on intro❤❤❤

Not a function, not a class (same 'str'), just a dirty hacks that looks like 'salty syntax'. Maybe all show go write simple, readable code instead?

the first thing, you are good when explain python. And the second thing, i like, because you use pycharm and not VS Code, of microsoft. Never, i will use ide of microsoft in my linux

To the moon with Cannafarm Ltd!

First!

second!

Hi, Why this doesn't work? import locale import datetime current = datetime.datetime.now() locale.setlocale(locale.LC_NUMERIC, 'fr_CA.utf-8') print(f'current = {current:n}') Displays: current = n NO ERROR Python 3.11.4

When I think back on all the time I wasted trying to do this stuff manually or just ignoring the ugly non formatting... 🤔😲🤯 This kinda highlights one of my biggest complaints in the whole world of programming. The sheer amount of minutia and details to memorize is overwhelming at times. It gets worse the more languages you accumulate. Everyone seems to have their own nomenclature and semantics. "MATCH case not SWITCH case which was something we were all used to BEFORE, thank you very MUCH! " Sometimes the function you want is right under your nose but you lack the nomenclature to know what your looking for. On the other hand even once you DO find that weirdly specific thing in the obscure library, often you wind up having to immerse yourself in Vogon poetry (Little 'Hitchhiker's Guide' reference there.. ) in order to use it. APIs are not always intuitively written, or have any reasonable docs (and usually tons more obscure minutia to memorize). THEN we get into the whole issue of licensing. Just a cluster#$^@. "Free for use.. On alternate Tuesdays IF you have a counter-signature from the Burgermeister of Sonoma." Sometimes just our limited capacities to completely grok the capabilities of a full language suite is the smallest bottleneck to creativity. Anyways, enough soapbox. I prostrate myself before thee Shifu! "May the luck of the 7 pillars of Gulu smile upon you at all times." 🙇‍♂👍

Locale that you used is not working for me. locale.setlocale(locale.LC_NUMERIC, locale: 'pl_PL.utf-8') ^ SyntaxError: invalid syntax
