我想从打开的输入框中获取值，并将它们变为crop1中的值。我是tkinter和编程的新手，所以我不确定如何将值放入函数中。很抱歉在短时间内有两个问题，这是我今天的最后一个问题。

答案 0 :(得分：2)
可能有更好的方法，但这很有效。添加一个按钮，当按下该按钮时，从文本条目中获取输入并将它们传递给裁剪功能。
def crop(self):
self.root = Tk()
self.root.wm_title("Insert Coords")
self.x0 = Entry(self.root)
self.x0.grid()
self.x1 = Entry(self.root)
self.x1.grid()
self.y0 = Entry(self.root)
self.y0.grid()
self.y1 = Entry(self.root)
self.y1.grid()
Button(self.root, text="Crop", command=self.close_crop).grid()
def close_crop(self):
self.crop1(self.x0.get(), self.x1.get(), self.y0.get(), self.y1.get())
self.root.destroy()
def crop1(self, x0, x1, y0, y1):
print x0, x1, y0, y1
