# range() - this function generates a list of numbers

upperBound = 5
range(upperBound) # this generates [0, 1, 2, 3, 4]
lowerBound = 2
range(lowerBound, upperBound) # this generates [2, 3, 4]
range(1, 11, 3) # generates [1, 4, 7, 10].
# range(lowerbound, uppperbound, step)
# an example of range() in action

# randrange() - generates a random number from a range of numbers

import random # this module is required to use randrange()
random.randrange(6) # generates a random number between 0 to 5 inclusive
