# code which counts the number of edges

How to write a code which counts the number of edges from a one vertex to another vertex in a directed bipartite graph?

code which counts the number of edges

Following up on vdelecroix's comment above, here's an example:

```
sage: G=graphs.PathGraph(5)
sage: G.distance(2,4)
2
```

Do you mean the distance ?

yeah,you are right.

I don't know if I am right because in your question you specify that the graph "directed" and "bipartite"... what those two properties have to do with computing a distance in a graph ? Anyway, can you reformulate your question in a clearer way ?
