Python has a number of functions that take an unlimited number of positional arguments. These functions sometimes have arguments that can be provided to customize their functionality. Those arguments must be provided as named arguments to distinguish them from the unlimited positional arguments. The bui...
From this, you should be able to work out why you’re getting an error about getting multiple values for the argumenta… What’s happening is that Python is passingselfto the method, as the first argument (which we have calleda), and is then passing the two other arguments that we spe...

It is also possible to make a function that doesn't capture any number of positional arguments, but does have some keyword-only arguments. The syntax for this is really weird.Let's make a multiply function that accepts x and y arguments:...
Positional arguments can also be passed to functions using an iterable object. Examples of iterable objects in Python include lists and tuples. The general syntax to use is: function(*iterable) Wherefunctionis the name of the function anditerableis the name of the iterable preceded by the aster...
