如何检查列表中是否包含列表，以及如何从列表中删除列表

def check_list_contains_sublist(main_list, sublist):
    for item in sublist:
        if item not in main_list:
            return False
    return True

main_list = [1, 2, 3, [4, 5]]
sublist = [4, 5]

if check_list_contains_sublist(main_list, sublist):
    print("The sublist is present in the main list.")
else:
    print("The sublist is not present in the main list.")

def remove_sublist(main_list, sublist):
    main_list.remove(sublist)

main_list = [1, 2, 3, [4, 5]]
sublist = [4, 5]

remove_sublist(main_list, sublist)
print(main_list)
