👋 Hello! I'm Alphonsio the robot. Ask me a question, I'll try to answer.

# In Python, how to create an array of n x m random integers?

The NumPy function `numpy.random.randint(low, high=None, size=None, dtype='l')`

is devoted to return random numbers. By setting the size option, the function can return a `numpy.ndarray`

of random integer :

```
>>> import numpy as np
>>> np.random.randint(low = 0, high = 10, size=(3,2))
array([[8, 7],
[8, 2],
[6, 2]])
```
