/// tip

The second argument to <a href="https://docs.python.org/3.8/library/os.html#os.getenv" class="external-link" target="_blank">`os.getenv()`</a> is the default value to return.

If not provided, it's `None` by default, here we provide `"World"` as the default value to use.

Then you could call that Python program:

<div class="termy">

```console

// combined with a row-function term.
func (p *qProp) combine(q qProp) {

	default:
		p.isAggregation = p.isAggregation || q.isAggregation
		p.isRowFunc = p.isRowFunc || q.isRowFunc
		if p.isAggregation && p.isRowFunc {
			p.err = errNestedAggregation

## Die Default-Exceptionhandler überschreiben

**FastAPI** hat einige Default-Exceptionhandler.

Diese Handler kümmern sich darum, Default-JSON-Responses zurückzugeben, wenn Sie eine `HTTPException` `raise`n, und wenn der Request ungültige Daten enthält.
