Question

我遇到此代码的问题。要计算抵押贷款你每月支付的抵押贷款金额，尽管我所说的每个人都无法确定问题所在。所以我来到这里看看你们中是否有人能够提供帮助？非常感谢：）

from tkinter import * #Imports the tkinter library
mortgage=Tk() #Names the interface as 'mortgage'
mortgage.geometry("800x500+200+200")  #Defines the dimensions of the interface
mortgage.title("Mortgage")

#calculation method
def Calculate():
    loantotal1=float(loantotal.get())
    interestrate1=float(interestrate.get())
    loanperiod1=float(loanperiod.get())

    interestCalculation =float( interestrate1 / 100)
    totalcost = float(loantotal1 * interestCalculation)
    numberofmonths=float(loanperiod1 / 12)
    monthlycost= float(totalcost / loanperiod1)
    monthly_period.set=("Your monthly payment %2.f "%monthlycost)

#variables
loantotal=StringVar()
interestrate=StringVar()
loanperiod=StringVar()
monthly_period=StringVar()

#interface
welcome_message=Label(mortgage,text="Find out how much you'll pay monthly    for your mortgage,",font="Arial 12 bold",fg="#000000").pack()
instruction_message=Label(mortgage,text="Enter your details below and then          Click submit:",font="Arial 12 bold",fg="#000000").pack()

loanTotal=Label(mortgage,text="Loan Total:",font="Arial 11     bold",fg="#000000").place(x=280,y=63)
loanTotal=Label(mortgage,text="£",font="Arial 11 bold",fg="#000000").place(x=550,y=63)
loanTotal_textbox=Entry(mortgage,textvariable=loantotal).place(x=400,y=65)

interestRate=Label(mortgage,text="Interest Rate:",font="Arial 11 bold",fg="#000000").place(x=280,y=88)
interestRate=Label(mortgage,text="%",font="Arial 11 bold",fg="#000000").place(x=550,y=88)
interestRate_textbox=Entry(mortgage,textvariable=interestrate).place(x=400,y=90)

loanPeriod=Label(mortgage,text="Loan Period:",font="Arial 11 bold",fg="#000000").place(x=280,y=113)
loanPeriod=Label(mortgage,text="Years",font="Arial 11 bold",fg="#000000").place(x=550,y=113)
loanPeriod_textbox=Entry(mortgage,textvariable=loanperiod).place(x=400,y=115)

Label(mortgage,textvariable=monthly_period).place(x=400,y=135)



submit_button=Button(mortgage,text="Calculate",command=Calculate,font="Arial 11 bold",fg="#000000").place(x=280,y=170)

mortgage.mainloop()

Answer 1

monthly_period.set=("Your monthly payment %2.f "%monthlycost)

您应该调用set方法，而不是分配给它...删除等号。

Answer 2

在代码的开头添加：

# -*- coding: utf-8 -*-

此外，如果您使用的是Python2，请按以下方式编写Tk导入：

from Tkinter import * #Imports the tkinter library

我无法弄清楚我的Tkinter按揭计算器有什么问题？任何建议都会很棒
