Merge multiple sublists where the value is not zero

What is the best way in Python to perform a merge where the value is not 0, resulting in the following outcome?

list = [
    [0, 0, 0, '', 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 'b', 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 'c', 0, 0],
    [0, 0, 0, 0, 0, 0, 0, '', 0],
    [0, 0, 0, 0, 0, 0, 0, 0, '']
]

[[0, 0, 0, '', 'b', 0, 'c', '', '']] # result

>Solution :

You can filter 0s from the sublists transposed with zip:

[next((i for i in s if i != 0), 0) for s in zip(*lst)]
