How to generate 20 random integers in python

How to generate 20 random integers in python: 1. Use sample in random to generate random non-repeating integers; 2. Use [random.randint] in numpy to generate completely random integers.

How to generate 20 random integers in Python:

1. Python generates random non-repeating integers using The sample

index = random.sample(range(0,20),20)

in random is to generate 20 non-repeating integers from 0 to 9

2. Python generates completely random integers, using random.randint

in numpy

index = np.random.randint(0,20,size=20)

generates 20 integers from 0 to 20 that may be repeated
