我可以在两个文本框中进行计算并在另一个文本框中得到结果吗

Question

我是编程新手，我正在编写我的第一个项目，我想知道我能否在两个文本框中进行计算并将结果传递给另一个文本框谢谢大家

这是我的代码：

from Tkinter import *
import Tkinter as tk


def add(x, y):
    return x+y


root = tk.Tk()
root.geometry('340x275+50+50')
root.title('Calculator')  
root.resizable(True, True)
root.iconbitmap("C://123//
icon.ico")

num_1 = Label(root, 
text="First number :")
num_1.grid(row=1, column=1)
num_2 = Label(root, 
text="Second number :")
num_2.grid(row=1, column=3)

textBox1 = Text(root, 
height=2, width=10)
textBox1.grid(row=1, column=2)
input1 = textBox1.get("1.0", 
END)

textBox2 = Text(root, 
height=2, width=10)
textBox2.grid(row=1, column=4)
input2 = textBox2.get("1.0", 
END)

textBox_result = Text(root, 
height=2, width=40)
textBox_result.grid(row=3, 
column=2)

btn_add = Button(root, 
text="+", command=add(input1, 
input2))
btn_add.grid(row=2, column=1)


root.mainloop()

作为新手教程。试试这个；

from tkinter import *

root = Tk()
root.title("Sum Two Numbers With GUI Using Python Source Code")
width = 400
height = 280
screen_width = root.winfo_screenwidth()
screen_height = root.winfo_screenheight()
x = (screen_width/2) - (width/2)
y = (screen_height/2) - (height/2)
root.geometry("%dx%d+%d+%d" % (width, height, x, y))
root.resizable(0, 0)

#==============================METHODS========================================
def calculate():
    if not num1.get() and not num2.get():
        print("Please enter a number")
    else:
        res=int(num1.get())+int(num2.get())
        lbl_text.config(text = "The answer is %d" % (res))
        num1.set=""
        num2.set=""

#==============================FRAMES=========================================
Top = Frame(root, bd=2,  relief=RIDGE)
Top.pack(side=TOP, fill=X)
Form = Frame(root, height=200)
Form.pack(side=TOP, pady=20)

#==============================LABELS=========================================
lbl_title = Label(Top, text = "Sum Two Numbers With GUI Using Python Source Code", font=('arial', 12))
lbl_title.pack(fill=X)
lbl_num1 = Label(Form, text = "Number 1:", font=('arial', 14), bd=15)
lbl_num1.grid(row=0, sticky="e")
lbl_num2 = Label(Form, text = "Number 2:", font=('arial', 14), bd=15)
lbl_num2.grid(row=1, sticky="e")
lbl_text = Label(Form)
lbl_text.grid(row=2, columnspan=2)

#==============================ENTRY WIDGETS==================================
num1 = Entry(Form, font=(14))
num1.grid(row=0, column=1)
num2 = Entry(Form, font=(14))
num2.grid(row=1, column=1)

#==============================BUTTON WIDGETS=================================
btn_calculate = Button(Form, text="Calculate", width=45, command=calculate)
btn_calculate.grid(pady=25, row=3, columnspan=2)

另一个对你来说很简单。

import tkinter as tk
from functools import partial

def findsum(l3, num1, num2):
    n1 = int(num1.get())
    n2 = int(num2.get())
    n3 = n1 + n2
    l3.config(text="Result = %d" % n3)
    return


root = tk.Tk()
root.title("Xiith.com")
root.geometry("700x500")

number1 = tk.StringVar()
number2 = tk.StringVar()

l1 = tk.Label(root, text="Enter 1st number").place(x=20, y=60)
l2 = tk.Label(root, text="Enter 2nd number").place(x=20, y=120)
t1 = tk.Entry(root, textvariable=number1).place(x=200, y=60)
t2 = tk.Entry(root, textvariable=number2).place(x=200, y=120)

labelResult = tk.Label(root)
labelResult.place(x=250, y=200)

findsum = partial(findsum, labelResult, number1, number2)

b1 = tk.Button(root, text="ADD", command=findsum).place(x=200, y=300)
b2 = tk.Button(root, text="Cancel", command=root.destroy).place(x=250, y=300)

root.mainloop()

我可以在两个文本框中进行计算并在另一个文本框中得到结果吗

Can i do a calculation in two text boxes and get the result in an other one
