The finally block is used to define code that should always execute, regardless of whether an exception was raised or not. It is typically used for clean-up actions, such as closing files or releasing resources.
The else block in a try...except structure is executed only if the code in the try block does not raise any exceptions. It allows you to define code that should run when no errors occur, making it useful for code that should execute only when the try block is successful.
A NameError occurs when you try to access a variable that has not been defined.
The try...except block is used to catch and handle exceptions or errors that occur during the execution of the code within the try block.
The pdb module is Python’s built-in debugger, which provides a way to step through code, set breakpoints, and inspect the state of your program while it is running. It is a powerful tool for debugging Python code and is built into the Python standard library.
