python设计一个电话计费程序？

import tkinter

window = tkinter.Tk()

window.title('电话计费')

window.geometry('260x170')

def calculate():

call = var.get()

min = e1.get()

if call == '0':

money = 0.40*int(min)

l2.config(text='国内长途'+str(min)+'分钟，话费'+str('%.2f'%money)+'元')

else:

money = 0.20*int(min)

l2.config(text='本地通话'+str(min)+'分钟，话费'+str('%.2f'%money)+'元')

var=tkinter.StringVar()

var.set(0)

b1 = tkinter.Radiobutton(window,text='国内长途',variable=var,value=0)

b1.pack()

b2 = tkinter.Radiobutton(window,text='本地通话',variable=var,value=1)

b2.pack()

l1 = tkinter.Label(window, text='输入通话时长')

l1.pack()

e1 = tkinter.Entry(window, width=20)

e1.pack()

b3 = tkinter.Button(window, text="计算", command=calculate)

b3.pack()

l2=tkinter.Label(window,text='')

l2.pack()

window.mainloop()

注意缩进

效果图

a=inputbox("请输入时间","提示")

if a="" then exit sub

b=iif(a<3,0.5,(a-3)*0.15+0.5)

if hour(time)<7 or hour(time)>19 then b=b/2

msgbox "话费为:" &b
