Python Exception-hantering Standard Exception List

Ruby's standard classes and modules raise exceptions. All the exception classes form a hierarchy, with the class Exception at the top. The next level contains seven different types −. Interrupt; NoMemoryError; SignalException; ScriptError; StandardError; SystemExit; There is one other exception at this level, Fatal, but the Ruby interpreter With no argument, or if the argument is the same as the receiver, return the receiver.

We just made a custom exception by subclassing StandardError, which itself subclasses Exception. In fact, if you look at the class hierarchy of any exception in Ruby, you'll find it eventually leads back to Exception. Here, I'll prove it to you.
