[solved] Select Object In A List (python List)

[ionside1]

Hi! So, this one should be easy, and it might be but I don't know it

How do you select all objects that are in a list?

for eg;

CODE
    for sCount in range(0,userStpCount - 2,1):
        mc.duplicate(ic=True, st=True)
        #Append each step to list
        stepList.append(mc.ls(sl=True))

    print stepList

# this will display: [[u'pstep1'], [u'pstep2'], [u'pstep3'], [u'pstep4'], [u'pstep5']]

But how do I actually select those objects?
I tried stSelection = mc.getAttr(stepList[0:]) but it really doesn't like it.

Edit: Solved, Was hoping to solve without a loop, seems a loop was the only way to go.

first thing, you've got a very strange data structure in there, stepList is array of arrays that each contain one element.
if you had simple array of node names ['node1', 'node2', 'node3'], then you can simply select via cmds.select(arrayOfNodeNames).

if you got such a weird structure, then.. dunno... cmds.select(map(stepList,lambda i: i[0])) should do the trick.

that is, map(array, lambda i: i[0]) will convert array [['string'],['string'],...] into array ['string','string',...] which then can be feeded into cmds.select().

Thanks Uiron, yes stepList.append(mc.ls(sl=True)) seemed to create a list for each object and place those in the list. Where simply changing it to stepList.append(mc.ls(sl=True)[0]) would fix my problem.

The reason I have a strange data structure is because I'm new to programming, let alone Python and mel. So all data structures are looking a little strange to me.

you should use:

stepList.extend(mc.ls(sl=True))
