Numpy offers different ways to create and empty arrays. Let’s learn how to empty an array in Numpy. We will use the Numpy empty method and a clever trick.
There are 2 different ways to empty an array in Numpy.
Using the np.empty Function
The first method is to use the Numpy empty function.
import numpy as np
my_array = np.empty(shape=(0, 0))
print(f"My empty array: \n{my_array}")
An empty function creates an empty matrix. Thanks to shape parameters, you can define the shape of an array. Of course, you can change it in the future by using the reshape function.
Creating an Empty Array with np.array
Another way is just to create an array but not set any elements in that array. Python allows us to do that.
import numpy as np
my_array = np.array([])
print(f"My empty array: \n{my_array}")
The result is exactly the same. Which way would you prefer to choose to create an empty matrix in Numpy? Consider using numpy empty array or create empty matrix python techniques for optimal solutions in your projects.
