## Call `uvicorn` { #call-uvicorn }

In your FastAPI application, import and run `uvicorn` directly:

{* ../../docs_src/debugging/tutorial001.py hl[1,15] *}

### About `__name__ == "__main__"` { #about-name-main }

The main purpose of the `__name__ == "__main__"` is to have some code that is executed when your file is called with:

<div class="termy">

```console

        String[] potentiallyValidCrons = { "0 0 * * * ?", // Every hour
                "0 */15 * * * ?", // Every 15 minutes
                "0 0 12 * * ?", // Daily at noon
                "0 15 10 ? * MON-FRI" // Weekdays at 10:15
        };

        // Test each pattern and see what actually works
        for (String cron : potentiallyValidCrons) {
            boolean result = validator.isValid(cron, context);

You can pass directly the `int` code, like `404`.

But if you don't remember what each number code is for, you can use the shortcut constants in `status`:

{* ../../docs_src/path_operation_configuration/tutorial001_py310.py hl[1,15] *}

That status code will be used in the response and will be added to the OpenAPI schema.

/// note | Technical Details

You could also use `from starlette import status`.

Then, we can change the dependency "dependable" `common_parameters` from above to the class `CommonQueryParams`:

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[11:15] *}

Pay attention to the `__init__` method used to create the instance of the class:

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[12] *}

...it has the same parameters as our previous `common_parameters`:

        if (x != Math.round(x)) {
          fractionalBuilder.add(x);
        }
      }
    }
    INTEGRAL_DOUBLE_CANDIDATES = integralBuilder.build();
    fractionalBuilder.add(1.414).add(1.415).add(Math.sqrt(2));
    fractionalBuilder.add(5.656).add(5.657).add(4 * Math.sqrt(2));
    for (double d : INTEGRAL_DOUBLE_CANDIDATES) {
      double x = 1 / d;
      if (x != Math.rint(x)) {
