In Python programming, the “assert” statement stands as a flag for code correctness, a vigilant guardian against errors that may lurk within your scripts.”assert” is a Python keyword that evaluates a specified condition, ensuring that it holds true as your program runs. When the condition i...
ZeroDivisionError: Occurs when dividing by zero. System Errors: These represent the critical issues involving the Python interpreter or system resources. They can technically be caught using a try-catch block, but it’s not recommended. They indicate the issues that require system-level debugging or...
For example, the unittest (PyUnit) module implements a unit testing framework that is already implemented and used in many other programming languages. Even if a developer hasn't used the Python version of this framework, he may be familiar with it from another programming language. A unit tes...
