I added some test input to give the code below, and it works fine for me. Can you give us some test input that fails for you? Can you also show us your test() function as it may the code in there that is failing. Ed class myObj: def __init__(self,a,b): self.a=a self.b=b def get_a(self): return self.a def get_b(self): return self.b input = ["1 2 3", "4 5 6"] L1=[] nobj=0 for line in input: L0=line.split() a=L0[1] b=L0[2] nobj=nobj+1 an_obj=myObj(a,b) L1.append(an_obj) # Filter data for i in range(1,nobj): for x in L1: # ... loop over all objects in list print "a -> ", x.get_a() # ... get value of a from current object print "b -> ", x.get_b() It returns: a -> 2 b -> 3 a -> 5 b -> 6 _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
