```Python
with open("./somefile.txt") as f:
    contents = f.read()
    print(contents)
```

Im Hintergrund erstellt das `open("./somefile.txt")` ein Objekt, das als „Kontextmanager“ bezeichnet wird.

If you are using third party libraries that tell you to call them with `await`, like:

```Python
results = await some_library()

### CVE-2022-3162: Unauthorized read of Custom Resources

A security issue was discovered in Kubernetes where users authorized to list or watch one type of namespaced custom resource cluster-wide can read custom resources of a different type in the same API group they are not authorized to read.

**Affected Versions**:
  - kube-apiserver v1.25.0 - v1.25.3
