How do I redirect stdin to a text file ? In C, this can be done with the

FILE *foo = freopen("in.txt", "r", stdin);
redirects stdin to the in.txt text file. Does anyone know a freopen()
Python equivalent ?
Notice that I'm not referring to shell redirection as the following
command line shows :
$ python myCode.py< in.txt
I need to hardcode the redirection inside the python source file.
I'm not sure how freopen() works in C, but perhaps you're looking for
redirecting sys.stdin:
import sys
old_stdin = sys.stdin # save it, in case we need to restore it
sys.stdin = open('myfile')
you can also restore stdin using sys.__stdin__ instead of saving the old
one, but in the case you or someone else is redirecting the stdin twice...
