difference of two sets (lists) in python

stb_list = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16]
passive_boxes_list = []
active_boxes_list = set(stb_list) - set(passive_boxes_list)
print active_boxes_list

I have got two lists. The number is going to be added into the passive_boxes_list dynamically (1-16).

How I can subtract stb_list from passive_box_list.

For example: if passive_boxes_list = [1 , 2 , 3] then active_box_list should be:

active_boxes_list = [4, 5,6, 7, 8, 9, 10, 11, 12, 13,14,15,16]

You should use the List Comprehension feature.
So you should have something like active_boxes_list = [x for x in stb_list if x not in passive_list]
Hope this help !

You can try this:

list = [1,2,3,4,5,6,7]
bleh=[1,2,3,10]
for x in bleh:
    if x in list:
        del list[list.index(x)]
print list
