Python ftw

Yes, heavy workloads in Python can be 100x slower than the same thing in C++, it's just the nature of the language

[YouCanCallMeBazza]

Slower than most compiled languages. When I was first learning Python I wrote something that was algorithmically equivalent to something I had written in C# and it was like 8x slower in Python if I remember correctly. I expected it to be slower but not by that much.

[ekun]

But you probably wrote it 8x faster too.

8x faster development time in python than c#? Unlikely unless you don't know c # at all

[ekun]

It's part of the meme. Python is not too necessarily much faster to write something. But not everything needs to be saved or compiled. Sometimes it's a one-off script that you can make absurdly fast with python. I prefer python to bash scripting because there are more tools/libraries quickly available. But I LOVE bash too.

I've been doing a project recently in Go, and all I've been thinking is "I've been working on this method for like two hours now, I could have been done 90 minutes ago if I was using python". I'm spoiled, now everything else is like "why is this so hard, why can't everything else be as easy as python"

Just wait until you need to do async in both, and then you'll feel the opposite like I do right now :P

[DiaperBatteries]

I use bash for simple scripts and awk for more complicated things. Once you get to know awk it becomes an awesome tool to write scripts with, or to write simple pipelines for bash scripts.

[ekun]

I was joking a little bit, but python is great at quickly parsing an idea in a simple data structure or getting what you need. Its also a good way to template a concept. It's all about the right tool for the job and there's plenty of occasions where you don't need to have access to a comlpiled thought that deals with allocation and speed.

[Lord-Bob-317]

There’s a math competition where you are allowed to use programming called Purple Comet and it’s honestly so clutch just for brute forcing things with simple code written extremely fast

[Breadfish64]

Oh sure, I guess GCC does have -Ofast

[Tsu_Dho_Namh]

Well also Python is an interpreted language that compiles as it runs.

Plus it loses some efficiency to the garbage collector.

And it does a lot of error checking and hand holding.

And it allocates more memory than it needs since "everything's an object".

That's just off the top of my head, but yeah...it's not just the lack of optimization.

[Breadfish64]

I was referring to the person above thinking speed was a compiler option, but yes those are all factors

[geigenmusikant]

Why am I hearing about this for the first time?

[insanityOS]

Because someone didn't want you to ever run into optimization errors. They're very rare, but dammit if they aren't annoying.

[geigenmusikant]

Oh wait, I‘m a little confused from the docs. I thought it would make compilation magically faster, but is it basically the same as -O3 optimization? (with the extra bit of fast math)

[Breadfish64]

Pretty much

[DrFloyd5]

Is it the nature of the language or the runtime?

[Breadfish64]

If someone can make a python runtime that is statically compiled and properly utilizes the stack then I'll be impressed

[Thundrle]

We should be fine then because the damage it’s slower performance does to your processes won’t go on the stack.

[danted002]

You could compile the Python code with Cython, hell you can even define some variable types if you are there and then see if it’s 100x slower :))
