Where can I find which exceptions are raised by Python built-ins?

I'm writing a decorator to validate some functions. I try to use built-ins as much as possible to do the heavy lifting, but I've been getting stuck on picking which exceptions I should catch when using them.

For example:

def Validated(fun):
    def ValidatedFun(*args, **kwargs):
        try:
            _ = dict(kwargs.get('untrusted_data', ()))
        except ? as e:
            raise BetterError('Additional relevant info') from e
        return fun(*args, **kwargs)
    return ValidatedFun

I'd like to know:

• What are the most-derived exceptions that dict (and other built-ins) explicitly raise?
• Where can I find documentation that lists them? (they aren't on https://docs.python.org/)
