Sure you can. You have to replace the file descriptor 0, that is,
"standard input"; sys.stdin reads from there. The standard way is to use
os.dup2:

c:\temp>type foo.txt
This line read from foo.txt
c:\temp>type redirect.py
import os

inp = open("foo.txt","r")
os.dup2(inp.fileno(), 0)
print "raw_input->", raw_input()

c:\temp>python redirect.py
raw_input-This line read from foo.txt

This is not
