How does one actually use this module? For example:
>>> import eratosthenes >>> eratosthenes.primes() <generator object at 0x640d0> >>> eratosthenes.primes().next() 2 >>> eratosthenes.primes().next() 2 >>> eratosthenes.primes().next() 2
How does one get beyond the first prime?
it = eratosthenes.primes() it.next() it.next()
or
# 'it' is shorthand for iterator
def primesToN(n):
it = eratosthenes.primes()
return [ x for x in it if x <= n ]You were running into problems because the primes() function returns a new generator. The values are in the generator not the function primes().
