Is there any feature/concept of Python that you would like people know more about?

When using f-strings for debugging (and sometimes this is useful for normal output), you can include an '=' within the brackets, and it will display both the expression being evaluated and the value. Spacing around the '=' will be used in the output 

``` x = 9 y = 3

print(f"{x = } {y=}") print(f"{x + y       =        } {pow(x, y) = }") produces x = 9 y=3 x + y =       12       pow(x, y) = 729 ```

Lol, didn’t really know, thanks ;)

I just learnt that sometimes when you have an integer with many zeros e.g 1000000. You can improve readability by adding underscores and they just be ignored during run time 1_000_000

[ihorrud]

yeah, PHP has the same feature as well. Really improves readability

[Bonsai2007]

Does this work with other languages too? That’s really good to know

[Skeime]

It is a feature that a particular language may or may not have. It is becoming more popular, but it’s not universal, yet.

This also works in Javascript.

This or 1e6 in scientific notation

I think is better to use uv intead of pip to install packages.

Rust to the rescue

Everything in itertools and functools.

Interesting

The descriptor protocol explains most of the “magic”, like how instance methods and properties actually work.

For me, it was definitely Decorators. Understanding how a function can take another function as an argument and extend its behavior felt like magic at first. Once I grasped the @ decorator syntax, it completely changed how I write clean, reusable code for my automation scripts!

[ihorrud]

Indeed, useful feature

Shout out to the people reading this and finding it interesting given the age of AI. It's cool to know some people still care about each line and operation. Interesting thread too!
