^Downloadable code & more! In this video we will answer the popular stack overflow question: What is the difference between Python’s list methods append and extend. https://stackoverflow.com/questions/2...

So let’s open ipython and do a quick list comprehension to create a list x.

And now let’s also create a list y.

Now the append function let’s you add a new object to a list. So we can add another int object to x by doing np.append with the number 100. Now you’ll see x is the same but with a 100 appended to the end.

With y we will do the same thing.

Now the .extend method is a bit different. Instead of adding on objects you use it to add on another iterable. In other words, you can use it to connect two lists together.

So x.extend(y). It does this in place. Now x is has ALL of y’s entries appended to it.

Let’s print that out so you can see it better. Now x is both x and y combined. So that is the difference. append lets you add one values and extend lets you add on lists.

So there you have it that is the difference between python’s list methods append and extend.
