Roll the dice
In the previous exercise, you used rand(), that generates a random float between 0 and 1.
As Hugo explained in the video you can just as well use randint(), also a function of the random package, to generate integers randomly. The following call generates the integer 4, 5, 6 or 7 randomly. 8 is not included.
import numpy as np
np.random.randint(4, 8)
NumPy has already been imported as np and a seed has been set. Can you roll some dice?

Exercise instructions
- Use
randint()with the appropriate arguments to randomly generate the integer 1, 2, 3, 4, 5 or 6. This simulates a dice. Print it out. - Repeat the outcome to see if the second throw is different. Again, print out the result.
Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# Import numpy and set seed
import numpy as np
np.random.seed(123)
# Use randint() to simulate a dice
# Use randint() again
