I don't have much experience with popen3. I do know that IDLE
(interactive interpreter) does something to sys.stdin, and that is
probably the problem you are seeing. Try your commands through the python
interactive interpreter started from a shell (DOS or Bash), see if it
still happens.
thx

Hej Caleb and others
I've been strugling with the same problem where i try to use popen3 to
run a
program. If I use a piped commandline
the program can read the file without problems but in the IDLE and with
popen it comes with an error.
I haven't been able to read the stdin either so the problem so far is
unsolved for my point.
But the newline command would explain my problems with the program.
Can it be a problem under windows since I'm using XP and the winpython
Hopefully Lars

It runs properly in a shell (bash), but on another matter:
'>>> r=sys.stdin.read(1)
g
'>>> r
'g'
'>>> r=sys.stdin.read(5)
1234567890
'>>> r
'\n1234'
'>>>
What exactly happened to my 1234567890? I understand that I am only
taking 5 characters, but where does the newline (\n) come from? Is
that a
remnant from when I terminated the previous 'g' input?
Thanks

Hi
You are probably typing this within IDLE. Try it after starting python
in a shell like DOS or Bash. Should work then (works for me, and I
also
get the AttributeError in IDLE.
Thanks

Why do I get an "AttributeError: read" message when I do:
import sys
r=sys.stdin.read()
??
I've tried:
r=sys.stdin.read(80)
r=sys.stdin.read(1)
same error message.
I couldn't find any reference to this function in my Python book (they
have
the stdout but not in).
Some sample code I saw uses this function in the same manner I am and
so I
am assuming this is the correct syntax?
Or is this a bug in Python 2.4?
