Final Thoughts See full list on www.nickmccullum.com This tutorial makes extensive use of the NumPy package for Python. Accordingly, let's start by importing NumPy into our development environment You can import NumPy under the alias np(which is standard convention) with the following command: If you've never used NumPy before, you might be wondering why we import the package under the npalias. It's because it makes it much easier to reference the package later in our program. Instead of calling objects and methods from numpy with the dot operator, we can simply call them from npinstead. If this is not clear, do not worry. We will see plenty of examples of this later in this tutorial. Return to the Table of Contents See full list on www.nickmccullum.com To understand how to use the np.appendmethod, you first need to understand what a NumPy array is. NumPy arrays are the main data structure available in the NumPy package. They are similar to normal Python lists, but come with additional functionality. There are a few different ways that programmers can create NumPy arrays, but the most common is to pass a Python list into the np.arraymethod. Here is an example: You could also pass the list into the np.arraymethod in a single command, like this: Here's what the my_arrayobject looks like if you print it to the Python console: The array()notation indicates that this is indeed a NumPy array. Return to the Table of Contents See full list on www.nickmccullum.com Now that you have an understanding of how to create a NumPy array, let's learn about the np.appendmethod. The appendmethod is used to add a new element to the end of a NumPy array. It accepts two parameters: 1. arr: the array that you'd like to append the new value to. 2. values: the value (or values) that you'd like to append to arr. Let's consider a few examples to see how the np.appendmethod works in practice. First, consider the following NumPy array: This NumPy array contains the integers from 1 to 3, inclusive. Let's add 4 to the end of this array using the np.appendmethod: The np.appendmethod actually returns the value of the new array. In this case, here is the output: In most cases, you will want to store the new array in another variable. This is done like any other variable assignment: using the =assignment operator. Here is an example: You can then reference second_array later in your program, perhaps by using the various NumPy methods and operationsthat come included in... See full list on www.nickmccullum.com One of the more common use cases of the np.appendmethod is to join two (or more) NumPy arrays together. This section of this tutorial will demonstrate this capability. For illustration's sake, we will be using the following NumPy arrays; Here's how you would append array2 to the end of array1 using the np.appendmethod: Here is what the output of this code looks like: Similarly, if you wanted to append array1 to the end of the array1, here's how you would do it: In this case, here's the output: It is even possible to append more than three arrays together using np.append. To demonstrate this, I will be using the following 3 arrays: You might think that the following code will properly append the three NumPy arrays together: However, this results in the following error: What is the solution? To append more than two NumPy arrays together using np.append, you must wrap all but the first array in a Python list. Here is how we would properly append array2 and array3 to array1 using np.app...
