    Some tests need reflective access to the internals of these packages. It is only the

    We could consider arranging things so that only the tests we know need this would get
    the add-opens. Right now that doesn't seem worth the effort, though.

## Why Virtual Environments { #why-virtual-environments }

To work with FastAPI you need to install <a href="https://www.python.org/" class="external-link" target="_blank">Python</a>.

After that, you would need to **install** FastAPI and any other **packages** you want to use.

        // Directory leasing requires SMB 3.0 or higher
        // MS-SMB2: Level 2 leasing (which includes directory leasing) is only supported in SMB 3.0+
        // We'll validate this when we actually need to use the session

        // Request base lease
        Smb2LeaseKey leaseKey = baseLeaseManager.requestLease(directoryPath, requestedState);

        // Create directory cache entry

{* ../../docs_src/query_params_str_validations/tutorial002_py310.py hl[7] *}

As in this case (without using `Annotated`) we have to replace the default value `None` in the function with `Query()`, we now need to set the default value with the parameter `Query(default=None)`, it serves the same purpose of defining that default value (at least for FastAPI).

So:

```Python
q: str | None = Query(default=None)
```

            // Mock send method
            public void send(final Object postcard) {
                // Mock implementation
            }
        };

        // Mock Postbox - no need to mock, the framework will handle it

        // Register components
        ComponentUtil.register(searchEngineClient, "searchEngineClient");
        ComponentUtil.register(systemHelper, "systemHelper");
