pythonw

I have a script that converts Google Earth .kml / .kmz files to shapefiles with a simple GUI interface written in Tkinter. My problem is that it works fine with a .py extension, but when saved out with a .pyw extension it stalls while reading my .kml files. There are no error messages and it doesn't crash. The GUI launches OK, etc, but it just stops and always at about the same place. I'm using Python 2.5, and had the same results with Python 2.7. Any ideas what could cause this? .pyw files are run differently than .py files -- they are associated with a different interpreter, pythonw.exe

If I save my code files as .pyw , no console window appears - which is what I want - but if the code includes a call to os.system , I still get a pesky console window. I assume it's caused by the call to os.system . Is there a way to execute other files from within my .pyw script without raising the console window at all? robince You could try using the subprocess module ( subprocess.Popen , subprocess.call or whatever) with the argument shell=True if you want to avoid starting a console window. You should use subprocess.Popen class passing as startupinfo parameter's value instance of

I have a program with a GUI that runs an external program through a Popen call: p = subprocess.Popen("<commands>" , stdout=subprocess.PIPE , stderr=subprocess.PIPE , cwd=os.getcwd()) p.communicate() But a console pops up, regardless of what I do (I've also tried passing it NUL for the file handle). Is there any way to do that without getting the binary I call to free its console? From here : import subprocess def launchWithoutConsole(command, args): """Launches 'command' windowless and waits until finished""" startupinfo = subprocess.STARTUPINFO() startupinfo.dwFlags |= subprocess.STARTF
