The following Code causes Python to crash import os import mmap data = mmap.mmap(open(<Certain File>,"r+").fileno(),os.path.getsize(<Certain File>)) assuming <Certain File> is present in the current working directory |

You are not doing anything to stop the file object being garbage collected (and therefore closed) before the mmap is created. Try import os import mmap f = open(<Certain File>,"r+") size = os.path.getsize(<Certain File>)) data = mmap.mmap(f.fileno(), size) |

Is it a crash, or do you get a exception with a nice message? |
