I need to write into list (list_sw_items) only names of all sw_items.

So at the end list_sw_items = [sw_item1, sw_item2, sw_item3, sw_item1_2, sw_item2_2, sw_item3_2, sw_item1, sw_item2 , sw_item3 ]

my code for now, where I keep getting error (KeyError) on sw_items

for k,v in data.items():
    for i,n in v['sw_items'].items():

What would be a way do achieve this?

Thanks!

for k,v in data.items():
   for i,n in v['components'].items():
        for j, l in n['sw_items'].items():
