Let’s learn how to empty an array in Numpy? We will use Numpy empty method and a clever trick.
There are 2 different ways to empty an array in Numpy.
The first method is to use Numpy empty function.
import numpy as np
my_array = np.empty(shape=(0, 0))
print(f"My empty array: \n{my_array}")
Empty function created an empty matrix. Thanks to shape parameters you can define a shape of an array. Of course you can change it in the future using reshape function.
Another way is just to create an array but not setting any elements to that. 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. Your choise which way you would prefer to choose to create an empty matrix in Numpy.
