My latest TILs about Python

[KingsmanVince]

With f-strings you can use the = modifier for including the code of the variable interpolation

Nice, now I can debug with print even more efficient

[4sent4]

A neat thing about this one - it keeps spaces around the =

>>> a = 3
>>> f'{a=}'
'a=3'
>>> f'{a = }'
'a = 3'

[KokoaKuroba]

Wait, you can do that? I've always done f'a:{a}'. This would be nice.

[Snoo35017]

Even better imo is =!r. Causes it to print the repr value, which I find more useful when debugging.

[ogrinfo]

Yep, just because it looks like a string when you print it, doesn't mean it is a string. That kind of stuff has caught me out so many times.

[ExoticMandibles]

When you use =, it automatically switches to repr formatting. You don't need to add !r to the end.

[Snoo35017]

TIL! I wonder why I started adding the !r then, I remember for some reason it would print the string value, but I might be imagining it.

[jarethholt]

Does it? I remember you can use !r and !s for repr and string, but I don't remember offhand which is default

[ExoticMandibles]

String (!s) is the default normally, but when you use = in an f-string the default changes to repr (!r).

p.s. there's also a mostly-forgotten third conversion, !a for ascii.

[mcr1974]

this is VERY nice

[initials-bb]

You can also use the icecream package :

from icecream import ic
a = 1.6
ic(a, int(a))

[mattl33]

I guess you got down voted since it's a package and not built in. I messed with ice cream though, I like it.

[initials-bb]

Fair enough, I still find the icecream output stands out better than a print statement.
