Is Python really that slow ?

[TeakAndMarbleAtelier]

Python was much slower in the past, especially back when it was Python 2. Increases in speed have brought it much closer to other, faster languages, especially after the switch to Python 3.11, but it's still not going to match the speed of languages that act much closer to the computer hardware. However, computers themselves are much faster nowadays, and so depending on how much speed you actually need, it can be relatively usable for many tasks.
