python,图形界面编程,tkinter,实现一个最简单的加法计算器的图形界面小程序

from tkinter import *def Calculate(): a1 = int(text1.get(‘1.0‘, END)) # 从行首取到行尾 a2 = int(text2.get(‘1.0‘, END)) a3 = a1 + a2 text3.delete(‘1.0‘, END) text3.insert(INSERT, a3)root = Tk()root.title(‘myTitle‘)label1 = Label(root, text = ‘First Number:‘)label1.grid(row = 0, column = 0)text1 = Text(root, width = 30, height = 1)text1.grid(row= 1, column = 0)label2 = Label(root, text = ‘Second Number:‘)label2.grid(row = 2, column = 0)text2 = Text(root, width = 30, height = 1)text2.grid(row = 3, column = 0)label3 = Label(root, text = ‘Result:‘)label3.grid(row = 4, column = 0)text3 = Text(root, width = 30, height = 1)text3.grid(row = 5, column = 0)button1 = Button(root, text = ‘Calculate‘, command = Calculate)button1.grid(row = 6, column = 0)mainloop()

  运行结果显示:
