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 ValueError:
>>> try:
... random.sample(range(1, 2), 3)
... except ValueError:
... print('Sample size exceeded population size.')
...
Sample size exceeded population size

random — Generate pseudo-random numbers
Almost all module functions depend on the basic function random(), which generates a random float uniformly in the half-open range 0.0 <= X < 1.0. Python uses the Mersenne Twister as the core generator.

Generate the range of data first and then shuffle it like this
import random
data = list(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)

I use list comprehensive to generate a list of all numbers 0 - 100. Then I use random.randint to generate a number between 0 - 100, and I shuffle the list that number of times. Then I use random.randint to generate another number between 0 - 100, which I use as the index for the element I select from my shuffled list, giving me my random number. Jk. random.randint(0,100)
