A python function for removing sublist from nested list

Question

I want to remove all occurrences of a list from list of lists. By that I mean I want to filter out all the occurrences of a given list. Eg

list = [[1,2,3], [3,2,1] ,[4,2,5],[1,2,3]]
list.removeList([1,2,3])
list=[[3,2,1],[4,2,5]]

I was thinking of using a filter or.remove() but it is giving me error. And for the filter I don't know what approach I should start with

Answer 1

Use a list comprehension

l = [sublist for sublist in l if sublist != [1, 2, 3]]

Answer 2

list1 = [[1,2,3], [3,2,1] ,[4,2,5],[1,2,3]]
list2= list1

for i in list1:
    if i==[1,2,3]:
        list2.remove(i)

With append

list1 = [[1,2,3], [3,2,1] ,[4,2,5],[1,2,3]]
list2= []

for i in list1:
    if i!=[1,2,3]:
        list2.append(i)
