Arrays (Not Built-In)

​So that’s list. There is something similar to list, at least in some ways, and you might have seen it in other languages, which is called array. Python actually does not have support of built-in array. Contrary to some of the places you might see explanations of Python arrays, but they are actually lists as we have just seen. But Python does have library which you can import to support arrays. Just like the following examples show:

As you can see that we have imported the array library (you can of course import some other library which supports array data type.) We then created a variable myArray using the array() method from the library to assign the 3 elements to it. In this example we then also made some change to the 2nd element of the array and print it out again. And then in the end, we used a len() method to tells us the length of the array – in this case the length of myArray is 3, meaning there are 3 elements at the position with indices 0, 1, and 2.

Python has a set of built-in methods that you can use on lists/arrays.
