We can view all the built-in exceptions using the built-inlocal()function as follows: print(dir(locals()['__builtins__'])) Run Code Here,locals()['__builtins__']will return a module of built-in exceptions,funct

This technique is pretty handy when you’re processing a piece of code that can raise multiple types of exceptions. Consider the following divide() function: Python >>> def divide(x, y): ... for arg in (x, y): ... if not isinstance(arg, int | float): ... raise TypeError...

Here is a list of Standard Exceptions available in Python. − Assertions in Python An assertion is a sanity-check that you can turn on or turn off when you are done with your testing of the program. The easiest way to think of an assertion is to liken it to araise-ifstatement (or...
The try and except blocks are used to handle exceptions. The assert is used to ensure the conditions are compatible with the requirements of a function. If the assert is false, the function does not continue. Thus, the assert can be an example of defensive programming. The programmer is mak...
