Check if multiple dimension Python array is empty
Clash Royale CLAN TAG#URR8PPPCheck if multiple dimension Python array is empty
I have a function that can return randomly shaped array like:
[[1], 2, [[3, 4], , [[5]]]
I need to check if the result array is empty and I can't use numpy or any other third party library.
Unfortunately,
if : ...
>>> False
which is fine, but
if [,]:...
>>> True
and I want this result to be false, so I came up with this:
def isEmpty(a):
return all([isEmpty(b) for b in a]) if isinstance(a, list) else False
Is there a built in way to get this result ?
If not this post might be usefull to someone somehow.
