How to find None in a list and replace it?

Question

Python

Let's say I have a list: How do I find None in it and replace it with
example = ['1', '2', None]
'None'

Answer 1

Something like this

new_list = ['None' if el is None else el for el in example]

Answer 2

>>> x = ['1', '2', None]
>>> [str(i) for i in x]
['1', '2', 'None']
>>>
>>> [str(i) if i is None else i for i in x]
['1', '2', 'None']

Answer 3

will replace anything that doesn't meet the condition

if something

(blank lines for example)

example = ['1', '2', None]
for pos, val in enumerate(example):
    if not val:
        example[pos] = 'None'
