Question

A simple way to convert a list to a tuple in Python is this:

tuple1=tuple(list1)

But if the list1 contains one or more lists, they remain the same. Is there a way that we can convert them as well?
E.g.

list1=[1,3,'abc',[3,4,5]]

goes to:

tuple1=(1,3,'abc',(3,4,5))

Answer 1

Recursion is all you need here:

def convert(l):
    return tuple(convert(x) for x in l) if type(l) is list else l

>>> convert([1,3,'abc',[3,4,5]])
(1, 3, 'abc', (3, 4, 5))
>>> convert([[[[[[]]]]]])
((((((),),),),),)
>>> convert(42)
42
