Handling an exception

1. A single try statement can have multiple except statements. ...
2. You can also provide a generic except clause, which handles any exception.

4. The else-block is a good place for code that does not need the try: block's protection.

What is exception in Python with example?

Python Built-in Exceptions

What do you mean by exception handling?

In computing and computer programming, exception handling is the process of responding to the occurrence of exceptions – anomalous or exceptional conditions requiring special processing – during the execution of a program.

What are the three types of error?

Errors are normally classified in three categories: systematic errors, random errors, and blunders. Systematic errors are due to identified causes and can, in principle, be eliminated. Errors of this type result in measured values that are consistently too high or consistently too low.

What is Python exception class?

In Python, users can define custom exceptions by creating a new class. This exception class has to be derived, either directly or indirectly, from the built-in Exception class. Most of the built-in exceptions are also derived from this class.
