You could use the all() function:

if all(x in L for x in wanted) and all(x not in L for x in not_wanted):
   # do stuff

Can you show me how to use this function with my example ? – Luk Apr 27 '16 at 14:44
@Luk: Just use `L = my_list[:3]; wanted = ["A_", "V", "3"]; not_wanted = ["ES", "SF"]` – Eugene Yarmash Apr 27 '16 at 14:56
