Sometimes, you have an API:
SNIP
Raises: PropertyError: If the property is not supported by this config source. LookupError: If the property is supported, but isn't available. ValueError: If the property doesn't have exactly one value. """ raise PropertyError
and you don't want your API to mask bugs. How would it mask bugs? For example, if API consumers do an:
try: x = foo.get_property_value(prop) except ValueError: # handle it
SNIP
If you don't want standard Python exceptions, such as ValueError to be confused with exceptions from your own app, just create your own custom exceptions such as class MyAppValueError(Exception): pass and raise these custom exceptions when necessary. No need to change Python or use convoluted logic. André Roberge
