Newbie: conventional instead of recursive way

[Igor Zivkovic]

Hello,

I have this function that prints each element of a list of strings. List 
may be complex and contain other lists. If an element is a list then the 
function calls itself recursively, if not then it prints the element.

def printList(L):
    if not L:
        return
    if type(L[0]) == type([]):
        printList(L[0])
    else:
        print L[0],
    printList(L[1:])

The problem is that I don't know how to write the same function using a 
conventional loop construct. This is one of my poor attempts: 

def printList(L):
    tmp = []
    while L:
        while type(L[0]) == type([]):
            tmp.insert(0, L[1:])
            L = L[:1]
        tmp.insert(0, L[0])
        L = tmp[:]
        if type(L[0]) == type(1):
            print L[0],
        del L[0]

Could you help me, please ?
