Is there anything in python that can replicate the functionality of freopen() in C or C++? To be precise, I want to replicate the functionality of:

Answer 1

If you're working on *nix platform, you can write your own freopen.

def freopen(f,option,stream):
    import os
    oldf = open(f,option)
    oldfd = oldf.fileno()
    newfd = stream.fileno()
    os.close(newfd)
    os.dup2(oldfd, newfd)

import sys
freopen("hello","w",sys.stdout)

print "world"
