NumPy in a Nutshell
NumPy in a Nutshell
Function array()
In fact, there are various functions in NumPy for creating arrays. Now, we'll explore one of the most commonly used ones, namely np.array()
. Below, you'll find an example of how to use this function:
# Importing NumPy import numpy as np # Creating array arr = np.array([1, 3, 5, 7, 9, 11, 13]) # Displaying array print(arr)
Let's now determine the type of object that this function creates. We can do this using the well-known function type()
.
Note
The
type()
function takes an object of any type and returns its type. The argument can indeed be of any type: number, string, list, dictionary, tuple, function, class, module, etc.
import numpy as np arr = np.array([1, 3, 5, 7, 9, 11, 13]) # Displaying array print(arr) # Displaying the type of created array print(type(arr))
We can see the type of the created array is ndarray
. But what does that mean?
ndarray - This object is a multidimensional homogeneous array with a predetermined number of elements.
Now it's time to practice!
Swipe to start coding
- You have to create two NumPy arrays. The first one should look like this:
[65, 2, 89, 5, 0, 1]
and the second one should look like this:[1, 2, 3]
. - Display these arrays on the screen.
- Display the type of these arrays on the screen.
