Can i prevent the random generator to generate already used numbers?

[MauserMan]

Thanks a lot all for your help, random.sample did the trick.


My code went from this:

import random

lottorad = [0, 0, 0, 0, 0, 0, 0]
unik_rad = False



while unik_rad == False:
        for x in range(0, 7):
                lottorad[x] = random.randint(1, 34)
        # lottoraden är nu fylld med 7 nummer.



        # kontrollerar om samtliga nummer i lottoraden är unika
        for x in range(1, 35):
                lika = lottorad.count(x)
                if lika > 1: # minst två lika nummer har hittats
                        unik_rad = False
                        break
                else:
                        unik_rad = True


lottorad.sort()
print(lottorad)

to this:

import random

lottorad = []
lottorad = random.sample(range(1, 34), 7)
lottorad.sort()
print(lottorad)

Thanks again, problem solved
