使用Scale拖动指示器，实现求和功能

[python]代码库

import tkinter

guo = tkinter.Tk()
guo.title("计算求和")
guo.geometry("370x300")

v = tkinter.IntVar()
lab1 = tkinter.Label(guo, text="求和数A：")
lab1.grid(row=0, column=0)
entl = tkinter.Entry(guo, textvariable=v, width=20)
entl.grid(row=1, column=0)
scl = tkinter.Scale(guo, label="数Ad取值范围-1000至1000", from_=-1000, to=1000, resolution=1,
                    digits=0, orient=tkinter.HORIZONTAL, variable=v, length=180)
scl.grid(row=2, column=0)

s = tkinter.IntVar()
lab2 = tkinter.Label(guo, text="求和数B:")
lab2.grid(row=0, column=1)
ent2 = tkinter.Entry(guo, textvariable=s, width=20)
ent2.grid(row=1, column=1)
sc2 = tkinter.Scale(guo, label="数B的取值范围-1000至1000", from_=-1000, to=1000, resolution=1,
                    digits=0, orient=tkinter.HORIZONTAL, variable=s, length=180)
sc2.grid(row=2, column=1)


def pa():
    p = scl.get() + sc2.get()
    b1.config(text="求和的结果为：" + str(p), state=tkinter.DISABLED)


def pb():
    scl.set(0)
    sc2.set(0)
    b1.config(text="求和", state=tkinter.NORMAL)


b1 = tkinter.Button(guo, text="求和", width=20, command=pa)
b1.grid(row=3, column=0, pady=5)
b2 = tkinter.Button(guo, text="清空", width=20, command=pb)
b2.grid(row=3, column=1)

guo.mainloop()
