To understand environment variables you can read [Environment Variables](../environment-variables.md){.internal-link target=_blank}.

## Types and validation

These environment variables can only handle text strings, as they are external to Python and have to be compatible with other programs and the rest of the system (and even with different operating systems, as Linux, Windows, macOS).

      // Runnable is executed more than once, allocate a wrapper that we know is safe to remove by
      // object identity.
      // A data structure that returned a removal handle from add() would allow eliminating this
      // allocation.

          new Runnable() {

        operation -->> tasks: Send background tasks

    opt Raise other exception
        tasks -->> dep: Raise other exception

    Note over dep: After yield
    opt Handle other exception
        dep -->> dep: Handle exception, can't change response. E.g. close DB session.
