带有 Tkinter 的 Python 代码简单计算器我是 Python 中的菜鸟有可能吗？

编程问答 2022-05-03

问题描述

import tkinter as tk
root = tk.Tk()
root.title("skaiciuotuvas")
e = tk.Entry(root,width=35,borderwidth=5)
e.grid(row=0,column=0,columnspan=3,padx=10,pady=15)
e.insert(0,0)

按钮动作功能

def button_click(number):

e.delete(0,"end")
current = e.get()
e.delete(0,"end")
e.insert(0,str(current) + str(number))



def button_clear():

    e.delete(0,"end")

这是一个简单的计算器，可以计算 num + num = res ：需要得到 num + num + num ...etc = rez 是否可以对这段代码进行验证

def button_add():

    first_number = int(e.get()) 
    global f_num
    f_num = int(first_number)
    e.delete(0,"end")

是否可以只使用 def button_add(): 函数？

def button_equal():

    second_number = e.get() 
    e.delete(0,"end") 
    e.insert(0,int(second_number)+ f_num)

按钮这是我的项目的规格值

button1 = tk.Button(root,text="1",padx=40,pady=20,command=lambda: button_click(-30))

button2 = tk.Button(root,text="2",command=lambda: button_click(-20))
button3 = tk.Button(root,text="3",command=lambda: button_click(-18))
button4 = tk.Button(root,text="4",command=lambda: button_click(-16))
button5 = tk.Button(root,text="5",command=lambda: button_click(-15))
button6 = tk.Button(root,text="6",command=lambda: button_click(-12))
button7 = tk.Button(root,text="7",command=lambda: button_click(-7))
button8 = tk.Button(root,text="8",command=lambda: button_click(8))
button9 = tk.Button(root,text="9",command=lambda: button_click(9))
button10 = tk.Button(root,text="10",padx=37,command=lambda: button_click(10))
button_15 = tk.Button(root,text="-15",padx=34,command=lambda: button_click(-15))
button_add = tk.Button(root,text="+",padx=39,command= button_add)
button_equal = tk.Button(root,text="=",padx=86,command= button_equal)
button_clear = tk.Button(root,text="C",command=button_clear)

#put 按钮在屏幕上

button2.grid(row=3,column=2)
button3.grid(row=3,column=1)
button4.grid(row=3,column=0)

button5.grid(row=2,column=2)
button6.grid(row=2,column=1)
button7.grid(row=2,column=0)

button8.grid(row=1,column=2)
button9.grid(row=1,column=1)
button10.grid(row=1,column=0)

button_add.grid(row=4,column=2)
button_15.grid(row=5,column=0)
button1.grid(row=4,column=1)

button_equal.grid(row=5,column=1,columnspan=2)
button_clear.grid(row=4,column=0)




root.mainloop()
