python generate list of random numbers without duplicates code example
Example 1: generate a list of random non repeated numbers python
import random
random.sample(range(1000), 50)
Example 2: python random number generator no duplicates
import random
def random_sample(count, start, stop, step=1):
def gen_random():
while True:
yield random.randrange(start, stop, step)
def gen_n_unique(source, n):
seen = set()
seenadd = seen.add
for i in (i for i in source() if i not in seen and not seenadd(i)):
yield i
if len(seen) == n:
break
return [i for i in gen_n_unique(gen_random,
min(count, int(abs(stop - start) / abs(step))))]
Example 3: python random number generator no duplicates
python -c "import random; print(sorted(set([random.randint(6,49) for i in range(7)]))[:6])"
