WebNov 7, 2024 · Function weight returns the weight of a given edge, with that edge identified by its two incident vertices. For example, calling weight (0, 4) on the graph of Figure 14.1.1 (c) would return 4. If no such edge exists, the weight is defined to be 0. So calling weight (0, 2) on the graph of Figure 14.1.1 (c) would return 0.
