Subprocess: PyDev vs. Console cmd.exe

Question

Subprocess: PyDev vs. Console cmd.exe

I am trying to call a process from python using subprocess.call as below:

from subprocess import call

exePath = 'C:\\Test\\EXE.exe'
inPath = 'C:\\Test\\IN.in'
outPath = 'C:\\Test\\OUT.out'
call([exePath, inPath, outPath])

This prints a few lines from EXE.exe, followed by an “Invalid handle”, but as a string and not as an error, which makes me think that this could be a message from EXE.exe:

Unzipping Solution...
0.0%                       The handle is invalid.

However, when I open cmd.exe and insert:

C:\Test\EXE.exe C:\Test\IN.in C:\Test\OUT.out

It works great.

Can someone point me in the right direction?

Thank!

I am running Python 2.7 64-bit on Windows 7.

EDIT:

Now it looks like a problem in PyDev, where the console cannot handle stdout from process rewrite strings. The code works differently from IDLE. Still looking for a fix for PyDev ...

exe , PyDev...

Python :

:

popen = subprocess.Popen(['myexe', 'params'], creationflags=subprocess.CREATE_NEW_CONSOLE)
popen.wait()

Linux ( CREATE_NEW_CONSOLE ):

args = ['xterm', '-e'] + ['myexe', 'params']
popen = subprocess.Popen(args)
popen.wait()
