In looking through the doc on the random module I came across
random.triangular():
========================================
random.triangular(low, high, mode)
Return a random floating point number N such that low<= N<= high and
with the specified mode between those bounds. The low and high bounds
default to zero and one. The mode argument defaults to the midpoint
between the bounds, giving a symmetric distribution.
New in version 2.6.
========================================
I fooled around with it a bit and wrote this rough demo:
<http://tutoree7.pastebin.com/s4J0Ww12>
The skewing and centering possible by varying the mode, are obvious,
but how is random.trangular() actually used?
From people who would know found at
http://docs.scipy.org/doc/numpy/reference/generated/numpy.random.triangular.html
"""The triangular distribution is often used in ill-defined problems
where the underlying distribution is not known, but some knowledge of
the limits and mode exists. Often it is used in simulations."""
