Python 在tkinter中计算输入

我正在使用Idle和tkinter.messagebox。我试图显示输入的计算结果。我一直无法确定如何捕获用户条目，然后运行计算并生成结果

所以，我希望用户能够输入数字，比如2和2。然后，我希望用户按下一个按钮。接下来，2 + 2的答案应该出现在空白条目标签中。

我的问题是如何捕获用户输入并在计算中使用它们，然后显示结果

mydict = {'good':0.7, 'average':0.5, 'optimal': 1, 'unacceptable': 0, 'major innovation': 1, 'minor innovation': 0.7, 'no innovation': 0.4, '1st lowest': 1, '2nd lowest': 0.7, '3rd lowest': 0.5, '4th lowest': 0.3}

# Widgets:
from tkinter import *
master = Tk()
label1 = Label(master, text = 'Bid Number', relief = 'groove', width = 16)
label2 = Label(master, text = 'Cost Score', relief = 'groove', width = 16)
label3 = Label(master, text = 'Past Performance', relief = 'groove', width = 16)
label8 = Label(master, text = 'Bid 1' , relief = 'groove', width = 12)
entry1 = Entry(master, relief = 'groove', width = 12)
entry2 = Entry(master, relief = 'groove', width = 12)
label9 = Label(master, text = 'Bid Score', relief = 'groove', width = 16)

def button_function():
    a = float( mydict[entry1.get()] ) * float( mydict[entry2.get()] )

button1 = Button(master, text = 'calculate', relief = 'groove', width = 12, command = button_function)
label16 = Frame(master, print(a))


#Geometry
label1.grid( row = 1, column = 1, padx = 10 )
label2.grid( row = 1, column = 2, padx = 10 )
label3.grid( row = 1, column = 3, padx = 10 )
label8.grid( row = 2, column = 1, padx = 10 )
entry1.grid( row = 2, column = 2, padx = 10 )
entry2.grid( row = 2, column = 3, padx = 10 )
label9.grid( row = 1, column = 8, padx = 10 )
label16.grid( row = 2, column = 8, padx = 10 )
button1.grid( row = 3, column = 4, columnspan = 2)

我不认为这个问题对任何人都有帮助，除了你目前的状态，但我认为你试图实现的目标可以通过替换：

def button_function():
    a = float( mydict[get(entry1)] ) * float( mydict[get(entry1)] ) * float( mydict[get(entry1)] ) *float( mydict[get(entry2)] ) * float( mydict[get(entry3)] ) *float( mydict[get(entry4)] ) * float( mydict[get(entry5)] ) * float( mydict[get(entry5)] ) * float( mydict[get(entry6)]) 
    ...

与：

此外，增加：

label16.grid()
button1.grid()

为了显示，未显示但显然需要显示小部件。

我解决了这个问题。我需要定义SuffyRead并将其插入空白，然后命令按钮显示答案。谢谢你的帮助

请提供一份报告。大约有3个小部件就足以生成您需要的演示代码了。我试着将其简化。谢谢这要好得多，但它会产生错误，而早期的代码没有。您是否阅读过任何文档或搜索过此网站？关于从入口小部件中获取数据，有很多很多问题，方法是有文档记录的。是的，我已经搜索过了，我没有发现任何有用的东西。如果您特别提到什么，请告诉我。我正在尽我最大的努力，我已经编写了两周的代码，并且一直在自学。这很有帮助，但我仍然无法单击calculate按钮返回label16中的值。为了清楚起见，我想在entry1-entry6中键入单词，单击计算，然后让数字显示在label16中。此外，我认为这将有助于其他人。事实上，这将有助于任何希望计算界面中表示的几何平均值的人。
