NOTE: This is an update to a previous post.
The following can be used to programmatically set stdin for testing under Python 3.x:
import sys
from io import StringIO
sys.stdin = StringIO()
setinput = lambda x: [
sys.stdin.seek(0),
sys.stdin.truncate(0),
sys.stdin.write(x),
sys.stdin.seek(0)]
Here is a quick example of using setinput() in Python 3.x:
setinput("Jeff")
name = input("Enter name:")
print(name)
