Then it isn't a normal variate.

Why? It's a perfectly simple procedure:
def __int__(self, x, y):
x = -1
while not 0 <= x <= 100:
x = normalvariate(x, y)
# do other stuff
That is the correct way to truncate a normal distribution.
Alternatively, truncate values past the end-points, but this will distort
the random distribution significantly:
x = max(0, min(100, normalvariate(x, y)))
You probably don't want that, as it will cause far more 0 and 100 values
than you would otherwise expect.

Why? Is the enter key on your keyboard broken?
