So, how do you figure out how many people on the guest list will actually attend the wedding? I get asked this question all the time. I wish I had a 100%- guaranteed-tried-and-true solution to offer or at least a magic crystal ball to whip out of my emergency kit to answer with, but alas, I can only offer my best advice.
Python Programming/Modules - Importing a Module. 1  To use the functions and classes offered by a module, you have to import the module... 2  The above imports the math standard module, making all of the functions in that module namespaced by the module name. It imports all functions and all classes, if any. You can import the module under a different name:
Python has two built-in functions that work with inheritance: 1  Use isinstance() to check an instanceâs type: isinstance(obj, int) will be True only if obj.__class__ is int or some class derived from int. 2  Use issubclass() to check class inheritance: issubclass(bool, int) is True since bool is a subclass of int.
