@KronoS [] = list, () = set, {} = dictionary
KronoS
KronoS
oh geez...
ok so what's the difference?
Ivo Flipse
Ivo Flipse
that's what you get when you don't read books ;)
list and dictionaries are mutable
KronoS
KronoS
@IvoFlipse agreed! or take any classes
Ivo Flipse
Ivo Flipse
sets are immutable
dictionaries are hash tables and store items based on key:value combos
they can't be sorted, because it uses its own sorting to make lookups blazingly fast
KronoS
KronoS
immutable being that once you make it it cannot be changed right?

lists can be sorted, index whatever
KronoS
KronoS
@IvoFlipse oh ok... that makes sense... if it's already 'sorted' according to a key... all we have to know if the key index
Ivo Flipse
Ivo Flipse
yes, but obviously the easy workaround when you do need to change it is to make a new set with the same content in a different order and overwrite the old one
KronoS
KronoS
@IvoFlipse right
