How to count number of occurrences of a specific list in a list in Python

Question

Suppose that I have a list like this :

test=[[1, 0, 0, 0], [1, 0, 0, 0], [0, 0, 0, 1], [1, 0, 0, 0], [0, 0, 0, 1],
    [0, 0, 1, 0], [1, 0, 0, 0], [1, 0, 0, 0], [0, 0, 0, 1], [0, 0, 0, 1],
    [0, 0, 0, 1], [1, 0, 0, 0], [0, 0, 0, 1], [0, 0, 0, 1], [0, 0, 0, 1],
    [1, 0, 0, 0], [1, 0, 0, 0],[0,0,0,0]]

How can I count the number of occurrences of say the list [1, 0, 0, 0]?

please make an attempt before asking? – depperm Jun 05 '18 at 18:50 — depperm, Jun 05 '18 at 18:50

Use list.count:

test.count([1,0,0,0])
