About generating N integer numbers without repetition - Otbredbaron - Jan-30-2018
Hello everybody,
I wrote this small piece of code to generate N numbers without repetition.
The algorithm should be fine but since I'm learning Python I'd like to know if my code is correct and if it can be improved with better functions because I have the feeling that it's too much "C style".
import random
random.seed()
N = 10
array = list(range(1, N + 1))
i = 1
a_size = N
while a_size > 1:
p = random.getrandbits(32)
k = p % a_size
print(array[k])
array[k] = array[a_size - 1]
a_size = a_size - 1
print(array[0])

Hello,
you can use random.sample function. Like this:
import random min_value = 1 max_value = 10 count = 5 random_numbers = random.sample(range(min_value, max_value), count) print(random_numbers)

1 + max_value

Thank you so much, well I wasn't expecting a function like this, good news
