And maybe you're right, the Python one could've been written:
if list is None:
list = []
which looks, now, also more readable to me as well.
Though there's a slight difference[1], I'd usually use
lst = lst or []
for your particular initialization use case.

Difference being
>>> lst = []
>>> other = lst
>>> if lst is None: # your code
... lst = []
...
>>> other.append(42)
>>> lst, other
([42], [42])
>>> lst = []
>>> other = lst
>>> lst = lst or [] # my proposal
>>> other.append(42)
>>> lst, other
([], [42])
