如何從python中的另一個方法值中減去方法值？

Question

我一直試圖從另一個方法值中減去一個方法值，但即使在我使用變量時它也會給我一個錯誤。

from tkinter import * 
statistics = Tk() 
screenwidth = statistics.winfo_screenwidth 
windowwidth = statistics.winfo_width 
distance = screenwidth - windowwidth 
statistics.geometry(+distance+'0') 

Answer 1

您正試圖減去兩個函數。你想減去調用函數的結果。試試這個：

from Tkinter import * 
statistics = Tk() 
screenwidth = statistics.winfo_screenwidth() 
windowwidth = statistics.winfo_width() 
distance = screenwidth - windowwidth 
statistics.geometry('+%s+0' % distance)
