Python can allow us to take screenshot easily. In this tutorial, we will introduce using python pillow library to take a screenshot for python beginners.

Take screenshot
im = ImageGrab.grab(bbox)
We will use ImageGrab.grab() function to get a snapshot of the screen.

Meanwhile, if you want to get a snapshot of full screen, you have two methods:
1.Set bbox = None, here is an example:
bbox = None im = ImageGrab.grab(bbox)
