An in-depth post to check out far more decorator use situations in excellent depth and with copyable code snippets
The code beneath is definitely an implementation for deciding the primality of a range utilizing the modulo operator:
Copied! After you connect with dir() Using the identify of a Python object being an argument, the operate tries to return a summary of valid characteristics for that particular object. This is the handy way to get an idea of what a supplied item can do.
