Sifting through the random module documentation a bit:
def rand_int(update=False):
if update:
dummy = random.random()
oldstate=random.getstate()
rand_num = random.randint(0,1000)
random.setstate(oldstate)
return rand_num
This will return a constant number when called with a False value for update
(the default), but will switch to returning a new number when called
with a True value once.
>>> rand_int()
644
>>> rand_int()
644
>>> rand_int(True)
120
>>> rand_int()
120
>>> rand_int()
120
Best, Wolfgang
