Python ImageGrab无法与输入配合使用

Question

In my program, I'm taking a screenshot of a part of my screen, which works. But when I add anything in front of calling the function it's in, it no longer gets past the ImageGrab part.

This works:

def takePictures():
    print("3")
    if __name__ == '__main__':
        print("1")
        im = ImageGrab.grab(bbox=(760, 250, 1160, 680))  # X1,Y1,X2,Y2
        print("2")
        im.save('ALL.png')
        #im.show()
 takePictures()

This doesn't:

def takePictures():
    print("3")
    if __name__ == '__main__':
        print("1")
        im = ImageGrab.grab(bbox=(760, 250, 1160, 680))  # X1,Y1,X2,Y2
        #^^^ Doesnt get past this line
        print("2")
        im.save('ALL.png')
        #im.show()
if input() == "":
    takePictures()

I've also tried it with inputs from keys on a different window and it's the same.

Answer 1

Your program will pause at

if input() == "":
    takePictures()

until you activate the python executing window and hit the enter key.

If you want to take screen shots, you can use, say

time.sleep(10)

giving yourself 10 seconds to activate the window you want to take a screen shot of.
