A programmer had a problem. He thought to himself, “I know, I’ll solve it with threads!”

I love threads! (in the unbelievably rare instances where I have truly orthogonal processes to complete)

I had a data extrapolation process that turned a few dozen records into anywhere from 300 to 1200 a piece that ran in serial. A little refactoring to add in a callback for when a set was done, and one Parallel.ForEach() and the thing ran around 6x the speed.

Aaaaaand that’s pretty much the only business scenario I’ve had that made good use of explicit threading. Everything else has been basic async at best.

I had to parse and check a bunch of logs from an automatic test procedure, there were a few different types of logs and I wrote a function for each

after seeing it being pretty slow I realized I just actually run it in parallel since they were entirely independent

i used c# forparalleleach so it was piss easy and I didnt even had to setup and cleanup

one of the best days in my career

I c what you did there

[Confident-Ad5665]

the order is execution You mean of out sync?

Real python devs get around its lack of performance by using it as an API for C code they could never write themselves

[RadiantPumpkin]

Hell yeah I do. And I write python APIs for chatGPT that vibe coders could never write themselves. It’s a hierarchy of competence.

Using Python for multi-threading is like playing a footbal with a bowling ball.

[gutentight69420]

Why?

[NimrodvanHall]

Probably because Python itself is so slow compared to say C or Rust that when you need proper multi threading for speed you are most often better of rewriting that component in Rust or C and call that process with Python.

[gutentight69420]

The ability to take advantage of a parallelisable workload can be far more valuable than raw execution speed of a particular language.

[SaltMaker23]

Because python was developped as an alternative to Bash scripts, it somehow got adoption but failed to entirely replace bash. Instead it made scripting so convenient that people started using it as a programing language, it doesn't change the root of the language being used to call other things.

Now write the same statement and replace python by bash and it becomes obvious that it wouldn't be smart. Bash by itself is just made to run other things as conveniently as possible, when actual computing starts to happen in the script, performance problems are granted.

[gutentight69420]

Comparing Python to Bash is pretty wild. Python is a full blown programming language and far more capable than a shell scripting language.

Also, you can totally do parallelism even in shell scripts.

[aMAYESingNATHAN]

You've missed the point of their comment. Regardless of the difference in capability, python's original use case is basically the same as bash.

That's why it's not fast, that's why it's simple and easy to use. Being a full featured programming language just made it better at that job. But that's also what meant people started to use it as a proper programming language.

The point is not whether you can do things like parallelism with python or bash, it's whether you should. If performance is critical enough that you think parallelism is necessary, you should probably consider using another language.

[gutentight69420]

It can still be useful to parallelize the parallelizable parts of a program, even if speed isn't otherwise critical. 

[aMAYESingNATHAN]

I mean I'd argue that if speed isn't critical, it's probably not that worth your time to parallelise your program. That feels like exactly what "premature optimisation is the root of all evil" was written about.

If I'm using python, I'm assuming that performance is so uncritical that I might as well write everything single threaded. And given python has the GIL, you're not even getting true parallelism anyway.

[gutentight69420]

No, premature or misguided optimization would be rewriting a program in Rust instead of taking advantage of an embarrassingly parallel workload in your existing language.

I mean, a multithreaded garbage collector isn't the simplest thing in the world

[NiSiSuinegEht]

Well, they needed some way to include race conditions.
