project: A new language specially designed for

writing Python extension modules.

Pyrex is more or less Python with C data types

added. You can write functions which freely

intermix operations on Python and C data, with

all Python reference counting and error checking

completely automated.

An example Pyrex module is shown below. For more

information, see:

http://www.cosc.canterbury.ac.nz/~greg/python/Pyrex/

where you can also download version 0.1 and try it

out. I'm very keen to get feedback on this, both to

find out whether people think it's useful, and to

help me debug it!

Oh, yeah, here's the example. It finds prime

numbers at C speed.

def primes(int kmax):

cdef int n, k, i

cdef int p[1000]

result = []

if kmax > 1000:

kmax = 1000

k = 0

n = 2

while k < kmax:

i = 0

while i < k and n % p[i] <> 0:

i = i + 1

if i == k:

p[k] = n

k = k + 1

result.append(n)

n = n + 1

return result
