有幾種方法可以顯示tkiner中的任何操作的結果。

您可以使用Label,Entry,Text，甚至彈出消息框。還有其他一些選擇，但這些可能會是你正在尋找的。

看看下面的例子。

我有一個簡單的添加程序，將采取2個數字并將它們添加在一起。它將顯示每種字段中的結果，您可以將其用作tkinter中的輸出。

import tkinter as tk

from tkinter import messagebox

class App(tk.Frame):

def __init__(self, master):

self.master = master

lbl1 = tk.Label(self.master, text = "Enter 2 numbers to be added \ntogether and click submit")

lbl1.grid(row = 0, column = 0, columnspan = 3)

self.entry1 = tk.Entry(self.master, width = 5)

self.entry1.grid(row = 1, column = 0)

self.lbl2 = tk.Label(self.master, text = "+")

self.lbl2.grid(row = 1, column = 1)

self.entry2 = tk.Entry(self.master, width = 5)

self.entry2.grid(row = 1, column = 2)

btn1 = tk.Button(self.master, text = "Submit", command = self.add_numbers)

btn1.grid(row = 2, column = 1)

self.lbl3 = tk.Label(self.master, text = "Sum = ")

self.lbl3.grid(row = 3, column = 1)

self.entry3 = tk.Entry(self.master, width = 10)

self.entry3.grid(row = 4, column = 1)

self.text1 = tk.Text(self.master, height = 1, width = 10)

self.text1.grid(row = 5, column = 1)

def add_numbers(self):

x = self.entry1.get()

y = self.entry2.get()

if x != "" and y != "":

sumxy = int(x) + int(y)

self.lbl3.config(text = "Sum = {}".format(sumxy))

self.entry3.delete(0, "end")

self.entry3.insert(0, sumxy)

self.text1.delete(1.0, "end")

self.text1.insert(1.0, sumxy)

messagebox.showinfo("Sum of {} and {}".format(x,y),

"Sum of {} and {} = {}".format(x, y, sumxy))

if __name__ == "__main__":

root = tk.Tk()

myapp = App(root)

root.mainloop()
