Show The Python exception class hierarchy consists of a few dozen different exceptions spread across a handful of important base class types. As with most programming languages, errors occur within a Python application when something unexpected goes wrong. Anything from improper arithmetic and running out of memory to invalid file references and unicode formatting errors may be raised by Python under certain circumstances. Most of the errors we'll explore in this series are considered Let's start by looking at the full Python exception class hierarchy, as seen below:
As we publish future exception-specific articles in this series we'll update the full list above to relevant tutorial and article links for each exception, so this post can act as a go-to resource for Python exception handling tips. Major Exception Types OverviewNext, let's briefly discuss each important top-level exception type. These top-level exceptions will serve as a basis for digging into specific exceptions in future articles. Before we do that, however, it's worth pointing out what might appear as a slight discrepancy when looking over the list of exception classes provided in Python. To illustrate, look closely at this small snippet of the Python exception class hierarchy and see if anything slightly strange pops out to you:
For developers that have worked with other programming languages in the past, what you might take note of is the distinction between using the word Yet, as we see in the hierarchy above, Python merely inherits from BaseExceptionThe The

Stay tuned for more in-depth articles examining each of these exceptions in greater detail, and be sure to check out Airbrake's robust error monitoring software, which provides real-time error monitoring and automatic exception reporting for all your development projects. Airbrake's state of the art web dashboard ensures you receive round-the-clock status updates on your application's health and error rates. No matter what you're working on, Airbrake easily integrates with all the most popular languages and frameworks. Plus, Airbrake makes it easy to customize exception parameters, while giving you complete control of the active error filter system, so you only gather the errors that matter most. Check out Airbrake's error monitoring software today with a 14-day trial and see for yourself why so many of the world's best engineering teams use Airbrake to revolutionize their exception handling practices! What is the difference between exceptions and errors?1. The error indicates trouble that primarily occurs due to the scarcity of system resources. The exceptions are the issues that can appear at runtime and compile time.
What are the two types of exceptions?There are mainly two types of exceptions: checked and unchecked. An error is considered as the unchecked exception.
What are the two types of exceptions in Java which are the differences between them?Difference Between Checked and Unchecked Exceptions in Java
To summarize, the difference between a checked and unchecked exception is: A checked exception is caught at compile time whereas a runtime or unchecked exception is, as it states, at runtime.
Which is the class that all exceptions inherit from?The Throwable class is the superclass of all Java exceptions and errors. It has two subclasses, Error and Exception but they don't represent checked and unchecked exceptions. The Exception class has a subclass called RuntimeException that contains most unchecked exceptions.
