This is a sequentialised variant of the well known sieve method (ab)using a dictionary as sparse array. |

<lang python>L = {} |

n = 2 |

while 1: |

if n in L: |

P = L[n] |

del L[n] # optional - just saves some memory. |
|||
else: |
|||
print n |
|||
P = [n] |
|||
for p in P: |
|||
npp = n+p |
|||
if npp in L: |

L[npp].add(p) |
|||
else: |
|||
L[npp] = set([p]) |
|||
n += 1</lang> |
