sorting - python - change element while in for loop -

let's have 3 lists:

lista = [5,6,2] listb = [7,1] listc = [5,3,6] 

i sort lists in 1 for loop, like:

for thislist in [lista, listb, listc]:  # edited, 'list' here     thislist = thislist.sort() 

where thislist lista, listb, listc, @ end lists this:

lista = [2,5,6] listb = [1,7] listc = [3,5,6] 

is there way this?

note - example, problem i'm dealing kinda harder, wanted make simple example of need.

--edit--

what if make custom sorting here? know that, example, can make custom sorting way: mylist = sorted(mylist, key= lambda val: val/2)

but i'm using sorted, not sort here.

can use custom sorting in sort?

asking cause given answers (thx btw ;) ) using sort...

you're close. want is:

for thislist in [lista, listb, listc]:     thislist.sort() 

the first problem in code using list loop variable, thislist inside loop. aren't same. so, whatever had assigned thislist earlier in module or interactive session, sorting on , on again, without affecting lista, listb, , listc.

the second problem list.sort method sorts list in-place , returns none, don't want return value. it's harmless overwrite thislist variable none, it's confusing reader, don't it.

since you've edited question different:

what if make custom sorting here? know that, example, can make custom sorting way: mylist = sorted(mylist, key= lambda val: val/2) … can use custom sorting in sort?

look @ docs sorted , list.sort. both of them take key argument, , both document same way. if can't guess whether work same way, take couple seconds test yourself:

>>> lst = [2, 11] >>> sorted(lst, key=str) [11, 2] >>> lst.sort(key=str) >>> lst [11, 2]
