Cauchy random number generator

import math
import random

def cauchy(location, scale):

# Start with a uniform random sample from the open interval (0, 1).
# But random() returns a sample from the half-open interval [0, 1).
# In the unlikely event that random() returns 0, try again.

    p = 0.0
    while p == 0.0:
        p = random.random()

    return location + scale*math.tan(math.pi*(p - 0.5))
