一、使用command=lambda: 的形式传参
代码如下
from tkinter import *
import tkinter.messagebox as messagebox
def createpage(master):
master = Frame(root)
master.pack()
Label(master, text=’num1′).grid(row=0, column=0, stick=W, pady=10)
e1 = Entry(master)
e1.grid(row=0, column=1, stick=E)
Label(master, text=’num2′).grid(row=1, column=0, stick=W, pady=10)
e2 = Entry(master)
e2.grid(row=1, column=1, stick=E)
# Button传递参数
Button(
master, text=’加’, command=lambda: btn_def(e1.get(), e2.get())
).grid(row=2, column=0, stick=W)
Button(master, text=’减’).grid(row=2, column=1, stick=E)
Label(master, text=’说明’).grid
