Hi, I have many set objects some of which can contain same group of object while others can be subset of the other. Given a list of sets, I need to get a list of unique sets such that non of the set is an subset of another or contain exactly the same members.
Tried to do the following: s1=set(['a','b','c']) s2=set(['a','c']) s3=set(['a','d','e','f']) s4=set(['r','k','l']) s5=set(['r','k','l']) L=[s1,s2,s3,s4,s5] ----------------------- > cleaned-up list should contain s1, s3, s5 Lu=[] # unique list of sets Lu.append( L[0] ) for i in range(1,len(L)): s=L[i] # check for equality if s in L: continue # check for subseting for j in len(Lu): s1=Lu[j] if len (s-s1)==0: continue elif len(s1-s)==0: Lu[i]=s1 # replace with the bigger But this does not work since I get Lu=[set(['a', 'c', 'b'])] What am I doing wrong? thanks -- http://mail.python.org/mailman/listinfo/python-list
