I would add f-strings to the list and some of the string methods especially .strip(), .split(), and .join()

For me, Specifically f”{x:,}” to return the value of x as a comma separated number string

fwiw `format(x, ',')` will do this too and looks a bit more readable imo

I think that holds true for just x, but not for, say,

f”Total Cost: {round(x / 1000000, 1):,}M”

The reason f-strings are not as popular is because they were added in 3.6 and no one could use them for backward compatibility reasons.

Now that 3.7 is the minimum supported version, it's safe to use.

F-strings are the reason I upgraded all my projects.

we also FINALLY got removeprefix() and removesuffix()! no more strange `string[:len(suffix)]`

f-strings are so incredibly handy!

Favorite thing I learned recently was that instead of doing

    print (f’some_var: {some_var}’)

one can just do

    print (f’{some_var=}’)

What’s the next cool thing I should know about f-strings?

I hadn't come across f'{some_var=}' before. Output looks like:

  some_var='abcd'

Great find!

It's even more useful for complex expressions e.g.

  f'{f(x, y)=}' -> 'f(x, y)=5'

In case anyone is wondering how they missed this: The feature was added in Python 3.8, so it wasn't part of the original f-strings feature set.

Wow, didn't know this one (just added to my lecture notes!) thanks
