A logical error occurs in Python when the code runs without any syntax or runtime errors but produces incorrect results due to flawed logic in the code. These types of errors are often caused by incorrect assumptions, an incomplete understanding of the problem, or the incorrect use of algorithm...

The difference with Test-Driven Development is that "unlike tests, which can usually only be used to show the presence of errors, types (used appropriately) can show the absence of errors. But although types reduce the need for tests, they rarely eliminate it entirely" (Brady, 2017, p.3)...

The BaseException class is at the top of Python’s exception hierarchy and includes common methods like __str__ and __repr__ that all exceptions can use. However, it is not recommended to use BaseException directly in code because it is too general and can catch all exceptions, including...

As we’ll see in later parts of the book, program units such as functions, modules, and classes are objects in Python too—they are created with statements and expressions such as def, class, import, and lambda and may be passed around scripts freely, stored within other objects, and so...
