How to implement an efficient infinite generator of prime numbers in Python?

in Haskell. So the answer cannot be as naive as Just do a Sieve . First of all you do not know how many consecutive primes will.. concoct 100 of them at a time. Would you use the same Sieve approach as well as the frequency of prime numbers formula I.. a Cookbook recipe with many other authors it shows how a Sieve of Eratosthenes has no intrinsic limits and the comments and..
