You could do something like this.

def printNestedList(lst):
    if isinstance(lst, list):
        for element in lst:
            printNestedList(element)
    else:
        print lst

myList = ['ciao', 1, ['mela', 'pera', 'banana'], [1, 2, 3]]
printNestedList(myList)

>>>
ciao
1
mela
pera
banana
1
2
3
