Hi, I got several dynamic lists a1, b1, c1, .... from a python application such as a1 = [1,5,3,2,5,...], the len(a1) varies. Same to b1, c1, .... With python, I would like to reorganize them into a tuple like t1 = ((a1[0],b1[0],c1[0],...),(a1[1],b1[1],c1[1],...),...) Anybody knows how to do that. Thanks for your help. Ouyang
