Why use indexing at all - when you have zip?

[val2 if val1 == 'null' else val1 for val1, val2 in zip(list1, list2)]

PS Recommended form to check type - isinstance

if isinstance(value, int):
.....

Test everything in a Python shell (iPython, Azure Notebook, etc.)

Someone gave you an advice you liked? Test it - maybe the advice was actually bad.
Someone gave you an advice you think is bad? Test it before arguing - maybe it was good.
You posted a claim that something you did not test works? Be prepared to eat your hat.
