If i needed speed i wouldnt be programming in python.

Is it just me... or is there a lot of python hate lately?
Nah, my personal hate of indented blocks has been there since the late 90s /s 8-)
Same for me. I have used Python for most things since the late 1990s. Love Python. Have always hated the poor performance... but in my case mostly it was good enough. When it was not good enough, I wrote C code.
Python is good for problems where time to code is the limiting factor. It sucks for compute bound problems where time to execute is the limiting factor. Most problems in my world are time to code limited but some are not.
Python compute performance has always sucked.
I get that... I'm not a developer, I'm a network engineer but I use a lot of python in my day to day operations. I always took python to be the "code for non-coders" which made it infinitely more approachable than some of the other languages.
I'm not running the F1 grand prix over here, I'm driving to get groceries, so what if it's not the fastest thing out there. Close enough is good enough for me. And in my experience that's what people are using python for, daily driving.
AI crowd using python probably @Big_Boss_77 @rimu
Ahh...that makes sense. I bet you're right.
People use Python a lot as a Matlab, Excel/VBA, or R alternative. That was my use for many years. Some of these are compute focused problems and if the dataset is large enough and the computations complex enough then speed can be an issue.
As far as loading packages and printing. Who cares. These are not computationally intensive and are typically IO bound.
I doubt it's useful for performance evaluation, however, if you are writing a paper and want to compare your algorithm to an existing one, this can be handy
Eh, maybe? It's probably only useful for large jumps, and timing is also probably good enough for that as well. With small jumps, instruction execution order matters, so a bigger number could very well be faster if it improves pipelining.
It's certainly interesting and maybe useful sometimes, but it's probably limited to people working on Python itself, not regular users.
Just remember that an optimized C program will run about 100x faster then a similar Python program in a compute bound problem. So yes Python is slow but often good enough.
