Write function result to stdin

I'm trying to write the results of a function to stdin.

This is the code :

def testy():
    return 'Testy !'

import sys
sys.stdin.write(testy())

And the error I get is :

Traceback (most recent call last):
  File "stdin_test2.py", line 7, in <module>
    sys.stdin.write(testy())
io.UnsupportedOperation: not writable

I'm not completely sure, is this the right way of doing things ?

Solution

  • You could mock stdin with a file-like object?

    import sys
import StringIO

oldstdin = sys.stdin
sys.stdin = StringIO.StringIO('asdlkj')

print raw_input('.')       #  .asdlkj
