index nested lists

[Alex]

hi at all,
If I have this list:
['ciao', 1, ['mela', 'pera', 'banana'], [1, 2, 3]]

if I want enumerate elements...I can see:
print lista
i = i + 1

ciao
1
['mela', 'pera', 'banana']
[1, 2, 3]
but, if I want to enumerate elements about nested lists ??, something
like:

ciao
1
mela
pera
banana
1
2
3

....How can I do ??

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

Cheers, Drea

One hidden suggestion in Andreas answer is to write your code in
english, if you can )
