Generate 'n' unique random numbers within a range [duplicate]
If you just need sampling without replacement:
import random random.sample(range(1, 100), 3)[77, 52, 45]
random.sample takes a population and a sample size
k and returns
k random members of the population.
If you have to control for the case where
k is larger than
len(population), you need to be prepared to catch a
try: random.sample(range(1, 2), 3)except ValueError: print('Sample size exceeded population size.') Sample size exceeded population size
Generate the range of data first and then shuffle it like this
import randomdata = range(numLow, numHigh)random.shuffle(data)print data
By doing this way, you will get all the numbers in the particular range but in a random order.
But you can use
random.sample to get the number of elements you need, from a range of numbers like this
print random.sample(range(numLow, numHigh), 3)
