Solve the following python programming problem given the following code:
def get_display_monitors(self) : 
    '
    Enumerates and returns a list of virtual screen
    coordinates for the attached display devices

    output = [
      (left, top, right, bottom), # Monitor 1
      (left, top, right, bottom)  # Monitor 2
      # etc...
   ]

    ' 
    display_coordinates = [] 
    def _monitorEnumProc(hMonitor, hdcMonitor, lprcMonitor, dwData) : 
        coordinates = (lprcMonitor.contents.left, lprcMonitor.contents.top, lprcMonitor.contents.right, lprcMonitor.contents.bottom) 
        display_coordinates.append (coordinates) 
        return True 
MonitorEnumProc = WINFUNCTYPE (ctypes.c_bool, ctypes.wintypes.HMONITOR, ctypes.wintypes.HDC, ctypes.POINTER (RECT), ctypes.wintypes.LPARAM) 
    enum_callback = MonitorEnumProc (self) 
    user32.EnumDisplayMonitors (None, None, enum_callback, 0) 
    return display_coordinates 

    
    

    Fix the buggy line: enum_callback = MonitorEnumProc (self)

#Here is Python program to fix the buggy line: enum_callback = MonitorEnumProc (self)
