four classes namedException,SystemExit,KeyboardInterrupt andGeneratorExit are derived. All the remaining built-in exception classes are derived directly or indirectly from theException class.The figure shows some of the classes derived fromException class; there are many other classes also. ...
RuntimeError When an error is not of any specific defined exception type, python calls it RuntimeError. NameError When a variable name we are trying to use is not defined.These were some of the built-in excpetion classes which are most commonly encountered while coding in python. For all...

Learn about Python's built-in exceptions, how to handle them, and improve your error management skills in Python programming.
In the past, Python has supported simple string messages as exceptions as well as classes. Since 1.5, all of the standard library modules use classes for exceptions. Starting with Python 2.5, string exceptions result in a DeprecationWarning, and support for string exceptions will be removed in th...
Explore the comprehensive list of built-in functions in Python, including their usage and examples to enhance your programming skills.
In one example of duck typing in Python, the+operator can be used to add two integers together. However, the same operator can also be used with string object types. Python will be able to differentiate between the two situations and produce a sum for the two integers, and separately, a...

34. Python - Data Classes Python - Built-In ModulesIn programming terminology, function is a separate, complete and reusable software component. Long and complex logic in a program is broken into smaller, independent and reusable blocks of instructions usually called a module, a subroutine or func...
“Python built-ins” shows the mechanism that Python uses to allow this direct access. Built-in types in Python include numbers, sequences, dictionaries, sets, functions (all covered in Chapter 3), classes (covered in “Python Classes”), standard exception classes (covered in “Exception ...
