## Technische Details { #technical-details }

Moderne Versionen von Python unterstützen **„asynchronen Code“** unter Verwendung sogenannter **„Coroutinen“** mithilfe der Syntax **`async` und `await`**.

Nehmen wir obigen Satz in den folgenden Abschnitten Schritt für Schritt unter die Lupe:

* **Asynchroner Code**
* **`async` und `await`**
* **Coroutinen**

/**
 * A class to represent the set of edges connecting an (implicit) origin node to a target node.
 *
 * <p>The {@link #nodeToOutEdge} map means this class only works on networks without parallel edges.
 * See {@link MultiEdgesConnecting} for a class that works with parallel edges.

To sign off a single commit:

`git commit --amend --signoff`

To sign off one or multiple commits:

`git rebase --signoff origin/master`

Then force push your branch:

`git push --force origin test-branch`
