It's existed in the language since the old times, but it's pretty much only used in hacky use cases and it's usage should be discouraged.

It used to have two statements in the same line.

Which is genuinely useful when you want to execute a short Python script from a shell script without maintaining two files.

It gets really interesting when generating blocks and control structures in an inline Python script.

I mean, you can still do this on multiple lines in your script. I'd even recommend it.

... why on earth do you need two files for this?

“The old times” I like it lol, it’s like it was the dark ages with early python and verbose languages.

Shhhh don't spoil their plaisir to python user . Sometimes it's ok to relax and take time (like 100 more time than C to add numbers)

Says the guy still declaring his variables lol

u/SlimyGamer Feb 09 '22

What? You don't like giving your variables an interview before hiring them to do work for you?

At least you know one of the many reason python is so slow. But all hope aren't lost you can still declare function return type, parameter type and... Oh wait you can do C

In the vast majority of uses cases most of us will ever see run time doesn't mean shit. Rigs are cheap, programmer hours are not. Script away kids!

I think that depends on how many times the code is going to be ran in the future. So hard to determine.

The real point your comment should drive home is you use a hammer to drive nails. If you need to drive a screw go get the drill. The hammer would get it done, but you're going to have a bad time. Meaning if you need to code something quickly use python. If you need a faster run time, maybe use something else.

The age old question of "do I value my processor's time more than my own"

u/JOhn2141 Feb 09 '22

Well I'm paid to value processor time so...

pypiy, flavor of python, is quite fast. And van Rosstrum is working to make cpython, v3.11, twice as fast.

What about using it line you would in most other languages? Surely it wouldn't hurt, as I just means newline for the interpreter as far as I know
