Until now, we invited community members to translate pages via pull requests, which were then reviewed by at least two native speakers. While this has helped bring FastAPI to many more users, we’ve also run into several challenges - some languages have only a few translated pages, others are outdated and hard to maintain over time.

/// tip

There are several `__init__.py` files: one in each directory or subdirectory.

This is what allows importing code from one file into another.

For example, in `app/main.py` you could have a line like:

```
from app.routers import items

    for (ListTestSuiteBuilder<Double> builder : builders) {
      suite.addTest(
          builder
              .withFeatures(
                  CollectionSize.ONE,
                  CollectionSize.SEVERAL,
                  CollectionFeature.RESTRICTS_ELEMENTS,
                  ListFeature.SUPPORTS_SET)
              .createTestSuite());
    }
    return suite;
  }
