### Typen und Validierung

Diese Umgebungsvariablen können nur Text-Zeichenketten verarbeiten, da sie außerhalb von Python liegen und mit anderen Programmen und dem Rest des Systems (und sogar mit verschiedenen Betriebssystemen wie Linux, Windows, macOS) kompatibel sein müssen.

  This question the Dodo could not answer without a great deal of
thought, and it sat for a long time with one finger pressed upon
its forehead (the position in which you usually see Shakespeare,
in the pictures of him), while the rest waited in silence.  At
last the Dodo said, `EVERYBODY has won, and all must have
prizes.'

  `But who is to give the prizes?' quite a chorus of voices
asked.

            // Write valid response data
            SMBUtil.writeInt4(15, buffer, 0);
            SMBUtil.writeInt4(16384, buffer, 4);
            SMBUtil.writeInt4(245760, buffer, 8);
            // Fill rest with random data
            for (int i = 12; i < buffer.length; i++) {
                buffer[i] = (byte) (i % 256);
            }

            int bytesDecoded = response.decode(buffer, 0, buffer.length);

/// tip

This is a somewhat advanced technique, and in most of the cases you won't really need it, as you can raise exceptions (including `HTTPException`) from inside of the rest of your application code, for example, in the *path operation function*.

But it's there for you if you need it. 🤓

## Types and validation { #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).
