How to write test cases in Python? To write test cases effectively in Python: Import the necessary testing framework, such as unit test or pytest. Define a test class inherited from the testing framework’s base class. Write test methods within the class, each representing a specific test cas...
By using these approaches, you can easily retrieve the size of a file in Python. Remember to handle exceptions, such asFileNotFoundError, to account for cases where the file does not exist. Operations with a File Extension When working with files in Python, you may often need to extract ...
While function-based decorators are common, Python also allows you to create class-based decorators, which provide greater flexibility and maintainability, especially for complex use cases. A class-based decorator is a class with a __call__ method that allows it to behave like a function. class...
