There might have been an easier way, but for the archives, here's the meat of what I did (as seen also in the python-win32 mailing list): import win32process from ctypes import * import time # Constants from winbase.h in .NET SDK STD_INPUT_HANDLE = c_uint(-10) # (not used here) STD_OUTPUT_HANDLE = c_uint(-11) STD_ERROR_HANDLE = c_uint(-12) # (not used here) startup = win32process.STARTUPINFO() (hProcess, hThread, dwProcessId, dwThreadId) = \ win32process.CreateProcess("C:\myConsoleApp.exe", "-X", None, None, 0, 0, None, None, startup) time.sleep(1) #wait for console to initialize # Use ctypes to simulate a struct from the Win32 API class COORD(Structure): _fields_ = [("X", c_short), ("Y", c_short)] topleft = COORD(0,0) CHARS_TO_READ = 200 result = create_string_buffer(CHARS_TO_READ) count = c_int() windll.kernel32.AttachConsole(c_uint(dwProcessId)) inHandle = windll.kernel32.GetStdHandle(STD_INPUT_HANDLE) outHandle = windll.kernel32.GetStdHandle(STD_OUTPUT_HANDLE) errHandle = windll.kernel32.GetStdHandle(STD_ERROR_HANDLE) # See Win32 API for definition windll.kernel32.ReadConsoleOutputCharacterA(outHandle, result, CHARS_TO_READ, topleft, byref(count)) print result.value -- http://mail.python.org/mailman/listinfo/python-list
