>>>languages['Python'] If there were already values in this list, we'd see the newly appended item appear after those values: >>>languages.append("JavaScript")>>>languages['Python', 'JavaScript'] Lists are fine
In this case, you can code a closure factory function like this: Python >>> def mean(): ... sample = [] ... def inner_mean(number): ... sample.append(number) ... return sum(sample) / len(sample) ... return inner_mean ... >>> sample_mean = mean() >>> sample...
Following answer is forpython, since I am not entirely sure which language you are asking about. There is a method for lists called append(). In case that is what you are referring to, listName.append(item) will add the 'item' (whatever variable or value you pass to it) to the end...

Just because pointers in Python don’t exist natively doesn’t mean you can’t get the benefits of using pointers. In fact, there are multiple ways to simulate pointers in Python. You’ll learn two in this section: Using mutable types as pointers Using custom Python objects Okay, let’s ...
While some of the examples you see below may not be WTFs in the truest sense, but they'll reveal some of the interesting parts of Python that you might be unaware of. I find it a nice way to learn the internals of a programming language, and I believe that you'll find it ...
