Question

我正在尝试制作一个python程序，该程序将输入到tkinter输入字段中的数字除以它们，然后将它们分类到列表中，然后创建一个显示哪个是最低的消息框。

取值的字段图像

然后，应将它们划分并以列表/字典的形式排列所有条目的商，并打印出最低的。

例如。项目＃1最便宜，项目＃3最便宜，等等。

到目前为止，这是我的代码：

from tkinter import * #Import the Tkinter module
from tkinter import messagebox #Imports the message box module
from tkinter import font #Imports fonts from tkinter
import json #Imports JSON

c = ('') #^
d = ('') #^
e = ('') #^
f = ('') #^
r = ('') #Result Var
aa = ('')
ba = ('')
ca = ('')
da = ('')
q1 = ('')
q2 = ('')
q3 = ('')
q4 = ('')

Answer 1

这是可以这样解决的问题：

entry1 = Entry()
entry2 = Entry()
entry3 = Entry()
entry4 = Entry()

def bestCur(*entries):
    # each entry should be a tuple e.g. (curEntry, mesEntry)
    entries = list(entries)
    for entry in entries:
        entry.append(float(entry[0].get())/float(entry[1].get()))
    entries.sort(key=lambda x: x[2])
    print(entries)


but1 = Button(master, text="press me", bg="red", command=lambda: bestCur([entry1, entry2], [entry3, entry4]))
but1.grid(row=10, column=1)

条目是tuple个条目组

例如在示例代码中，当entries为but1

时，我给出了entries = ([entry1, entry2], [entry3, entry4])

.bestCur(*entries)函数是对条目进行划分和排序的函数。

从tkinter窗口获取值，对其进行划分，然后在列表中对它们进行排序
