IDLE subprocess startup error

问题

I have the code below in a file called code.py. I am using IDLE to edit the file. When I click Run>Run Module I get the error:

"IDLE's subprocess didn't make connection. Either IDLE can't start a subprocess of personal firewall software is blocking the connection."

I am using Windows 7 Ultimate 64bit, but I have the 32bit version of Python 2.7 installed.

I have looked for a solution on this site as well as others but all of them seem to recommend deleting something called tkinter.py (I have no idea what this is) or to turn off my firewalls (I have none enabled aside from Microsoft Security Essentials which isn't a firewall.)

    box = (x_pad+1,y_pad+1,x_pad+641,y_pad+480)
    im = ImageGrab.grab(box)
    im.save(os.getcwd() + '\\full_snap__' + str(int(time.time())) +

    main()

    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTDOWN,0,0)
    time.sleep(.1)
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTUP,0,0)
    print 'Click.'          #completely optional. But nice for debugging purposes.

def leftDown():
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTDOWN,0,0)
    time.sleep(.1)
    print 'left Down'

def leftUp():
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTUP,0,0)
    time.sleep(.1)
    print 'left release'

def mousePos(cord):
    win32api.SetCursorPos((x_pad + cord[0], y_pad + cord[1])

def get_cords():
    x,y = win32api.GetCursorPos()
    x = x - x_pad
    y = y - y_pad
    print x,y

The thing is "python.exe" is being obstructed by "tkinter.py") that you created(i.e., you have written a program with Tk() and named it as tkinter.py and saved that in the root folder of python). And that's it just make sure that you don't save any program file directly in the root folder of python.

Another fix!!! Hopefully this will help someone.

I had the same problem and noticed something quite interesting. I had accidentally named a file (inside the desktop folder I was working in) "tkinter" (it will cause the same problem if you rename a file by any reserved keyword, I assume). Everytime I ran or attempted to run this file, it created a pycache folder, and the error you mention above came up. Deleting the erroneously named python file solved the problem.

So - look for ANY files (in the folder you are working with or indeed the root folder) that are named after any reserved words. Delete them. Hopefully it'll work!

I had the same problem. what i did that solved it, was to move every .py file that i had created in "C:\Python33" folder, to a sub-folder that i named "Examples". seems like one of my files was the cause of this problem.

I also had the following problem. My file was named code.py, and was working fine untill I installed Canopy, and numpy.

I tried reinstalling python, but what solved the problem for me was simply renaming the file. I called my file myCode.py, everything started working fine. Strange problem...
