exception_guard context manager and decorator

[Steve D'Aprano]

As discussed in the Python-Ideas mailing list, sometimes we want to suppress a
particular kind of exception and replace it with another.

For that reason, I'd like to announce exception_guard, a context manager and
decorator which catches specified exceptions and replaces them with a given
exception (RuntimeError by default).

or just

It should work with Python 2.6 through 3.6 and later.

    try:
        with exception_guard(ZeroDivisionError):
            1/0  # raises ZeroDivisionError
    except RuntimeError:
        print ('ZeroDivisionError replaced by RuntimeError')
