在http://www.lfd.uci.edu/~gohlke/pythonlibs/#pil上获取win-
amd64-py2.7的PIL 。
from PIL import ImageGrabim = ImageGrab.grab()im.save('screenshot.png')更新：使用pywin32（http://sourceforge.net/projects/pywin32/）代替PIL来获取多个虚拟屏幕的屏幕截图：
import win32gui, win32ui, win32con, win32apihwin = win32gui.GetDesktopWindow()width = win32api.GetSystemMetrics(win32con.SM_CXVIRTUALSCREEN)height = win32api.GetSystemMetrics(win32con.SM_CYVIRTUALSCREEN)left = win32api.GetSystemMetrics(win32con.SM_XVIRTUALSCREEN)top = win32api.GetSystemMetrics(win32con.SM_YVIRTUALSCREEN)hwindc = win32gui.GetWindowDC(hwin)srcdc = win32ui.CreateDCFromHandle(hwindc)memdc = srcdc.CreateCompatibleDC()bmp = win32ui.CreateBitmap()bmp.CreateCompatibleBitmap(srcdc, width, height)memdc.SelectObject(bmp)memdc.BitBlt((0, 0), (width, height), srcdc, (left, top), win32con.SRCCOPY)bmp.SaveBitmapFile(memdc, 'screenshot.bmp')
