### O que são gerenciadores de contexto

"Gerenciadores de Contexto" são qualquer um dos objetos Python que podem ser utilizados com a declaração `with`.

Por exemplo, <a href="https://docs.python.org/3/tutorial/inputoutput.html#reading-and-writing-files" class="external-link" target="_blank">você pode utilizar `with` para ler um arquivo</a>:

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

                        // error, based on the repository's checksum checking policy.
                        if (firstRun) {
                            logger.warn("*** CHECKSUM FAILED - " + e.getMessage() + " - RETRYING");
                            retry = true;
                        } else {
                            handleChecksumFailure(checksumPolicy, e.getMessage(), e.getCause());
                        }
