"""Random numbers in python

# First we need to import the random module:
import random

# We can set the seed for the random number generator by:
random.seed(1)
# this ensures that the series of number that are generated is
# reproducible

# get a random number between 0 and 9:
print random.randrange(0, 10)

a = range(0, 100)
# shuffle the elements of the list:
random.suffle(a)

print random.uniform(0, 1)

# Let's create an instance of the Random class:

rand = random.Random(10)

# The argument we gave the constructor is the seed

# now you can use all the functions in the random module as methods
# of the instance we created:

print rand.randrange(0, 10)
a = range(0, 100)
# shuffle the elements of the list:
rand.suffle(a)
print rand.uniform(0, 1)
