I want to generate pairs of random numbers that the first number is smaller than the second one like [[3 8] [2 5] [8 9] [8 10] [5 9] [3 7]]. I tried with the following code but since all the values generated randomly some of the first elements are greater than the second ones and some of them are equal.
a=random.randint(1, 10)
b = np.random.randint(1,10,(a,2))
print(b)
Seems most solution so far don't take into account that two independently generated random numbers could be equal. (Which OP states he doesn't want).
I think sample is better.
from random import sample
sorted(sample(range(1,10),2))
This guarantees 2 unique numbers in increasing order.
One approach world be to sort the random numbers after generation
sorted([randint(1, 10), randint(1, 10)]) # [3, 7], [4, 6], [1, 10]
Well, since the number are just random, you can simply add the following to you code:
Same as you did:
a = random.randint(1, 10)
b = np.random.randint(1, 10, (a, 2))
Then:
b = [sorted(pair) for pair in b]
