How to remove every occurrence of sub-list from list

Question

I have two lists:

big_list = [2, 1, 2, 3, 1, 2, 4]
sub_list = [1, 2]

I want to remove all sub_list occurrences in big_list.

result

Answer 1

More readable than any above and with no additional memory footprint:

def remove_sublist(sublist, mainlist):

    cursor = 0

    for b in mainlist:
        if cursor == len(sublist):
            cursor = 0
        if b == sublist[cursor]:
            cursor += 1
        else:
            cursor = 0
            yield b

    for i in range(0, cursor):
        yield sublist[i]

This is for onliner if you wanted a function from library, let it be this

[x for x in remove_sublist([1, 2], [2, 1, 2, 3, 1, 2, 4])]
