Optimising my Quick sort algorithm (does it operate in-place?)

Question

Hey, my Quick sort algorithm works just fine and it's fairly quick I'd say, but could someone please check it and tell me if it operates in-place (doesn't use any additional space except for the given list)? I wrote it that way and I'm 90% sure it does but these things are tricky so I said I'd double check. Also any optimisations come in mind?
I appreciate any help :)

Answer 1

i would say it's in-place
- Since you are not creating any extra list or array.... each operation you do is on same list... so it's in-place
- But in each operation the list keeps changing its size(pop and append or pop and insert)
- for optimization, i suggest u to use swap like a, b=b, a instead of deleting and inserting... because insert() takes a lot of time... at least greater than a simple swap...
also that's a good piece of implementation...
