In this NumPy tutorial, you’ll learn how to use the NumPy arange function in Python. In the following example, this function will create a NumPy array of numbers with a step size of 4. All the numbers will be between 0 and 20. A number 0 will be included and a number 20 will be excluded.

# import numpy module
import numpy as np

# create a numpy array
var = np.arange(0, 20, 4)

# print the array
print(var)

Output:

[ 0  4  8 12 16]
