[Jan Knop]

Hello

I am writing a Windows application where I need to redirect stdin,
stdout and stderr from Python. to my application
Is it a simple way of do it ?
Has anyone done it using Winsock ?

import sys
sys.stdin, sys.stderr, sys.stdout = map(open, 'in.txt err.txt out.txt'.split(),
'r w w'.split())

import sys
sys.stdin, sys.stderr, sys.stdout = map(open, 'in.txt err.txt out.txt'.split(),
'r w w'.split())

That is why map should be deprecated asap

sys.stdin = open("in.txt")
sys.stdout = open("out.txt","w")
sys.stderr = open("err.txt","w")

The obfuscation in the above example was intended not to immediately overwhelm
the OP (who expected having to use some winsock thingy) with simplicitly and
clarity, but now you've spoilt it.

Hi

Actually that what I wat in the end is a method for subsclassing the
python stdio's into my application window. This means that Python runs
in background with all threes stdio streams redirected .
This is I believe somehow done in the Komodo program from
ActiveState
As far as I have found out You need to define a Input and output
class and imlement Read Readline , Write and WriteLine method in
these classes.
Otherwise it will be necessary to somehow capture the Stdin stdout
streams from python console and redirect them .

with regards
