How can I generate a random number which will not be generated again afterwards? [duplicate]

• How do I create a list of random numbers without duplicates? 15 answers

I'd like to create a program which will generate random numbers between 1 and 30 until all numbers have been generated once. Essentially, I want to generate random numbers which will never be generated again afterwards.

import random
test = random.randint(1, 30)

This is what I have so far, but of course, a number already generated will be generated again.
