randint() function is used to generate random integers in NumPy. This function does not include the upper bound of the interval, so instead of writing 9 in the upper bound, you have to write 10. Also, randint() is found in NumPy's random module.
import numpy as np arr = np.random.randint(0, 10) print(arr)
Output
8
When you do not specify the size parameter, then only a single random integer is generated. If you want to generate 2 dimensional NumPy array, then pass a tuple of integers to the size parameter.
import numpy as np arr = np.random.randint(0, 10, size=(4, 3)) print(arr)
Output
[[6 8 9] [1 5 4] [5 8 8] [2 7 2]]
The above code will generate a 2 dimensional NumPy array having 12 elements.
