Hello, I'm new in Matplotlib and am writing in order to ask a help. I've developed a little software with Python that, by inserting a number, calculate a list of couples. Example Insert a number: 4 Couples: [[4, 3], [4, 2], [4, 1], [3, 2], [3, 1], [2, 1]] What I'd like to do is drawing with Matplotlib a graph having as nodes 1, 2, 3, 4 and as edges among the nodes the above couples. (sample drawing: https://networkx.lanl.gov/) Can you help me to make this operation please? My code at the present is the following one. n = input("Insert a number" ) a = range(n) p = 0 q = 1 coppie = [] coppia = [] while len(a)  p != 1: coppia.append(len(a)  p) coppia.append(len(a)  p  q) coppie.append(coppia) coppia = [] if len(a)  p  q != 0: q = q + 1 if len(a)  p  q == 0: p = p + 1 q = 1 print coppie I suppose it is quite easy but in spite of this have some difficulty. Really many thanks for the help! Best, Nico
