用python语言开发一个可视的，可点击的，有页面的计算器 包括：Python的基本数字运算（加、减、乘法、除法、平方、除法、sin、cos等）

好的，我可以给你提供一个基于Python和Tkinter库的计算器示例代码，包括数字运算（加、减、乘、除、平方、sin、cos等）。

代码如下：

from tkinter import *
import math

class Calculator:
    def __init__(self, master):
        self.master = master
        master.title("Calculator")

        # Create Entry widget to display input and results
        self.entry = Entry(master, width=35, borderwidth=5)
        self.entry.grid(row=0, column=0, columnspan=4, padx=10, pady=10)

        # Create buttons
        self.button_1 = Button(master, text="1", padx=40, pady=20, command=lambda: self.button_click(1))
        self.button_2 = Button(master, text="2", padx=40, pady=20, command=lambda: self.button_click(2))
        self.button_3 = Button(master, text="3", padx=40, pady=20, command=lambda: self.button_click(3))
        self.button_4 = Button(master, text="4", padx=40, pady=20, command=lambda: self.button_click(4))

        self.button_7 = Button(master, text="7", padx=40, pady=20, command=lambda: self.button_click(7))
        self.button_8 = Button(master, text="8", padx=40, pady=20, command=lambda: self.button_click(8))
        self.button_9 = Button(master, text="9", padx=40, pady=20, command=lambda: self.button_click(9))
        self.button_0 = Button(master, text="0", padx=40, pady=20, command=lambda: self.button_click(0))

        self.button_add = Button(master, text="+", padx=39, pady=20, command=self.button_add)

        self.entry.delete(0, END)

    def button_square(self):
        first_number = self.entry.get()
        result = float(first_number) ** 2
        self.entry.delete(0, END)
        self.entry.insert(0, result)

    def button_sin(self):

root = Tk()
my_calculator = Calculator(root)
root.mainloop()

这段代码会创建一个具有数字和运算符键的计算器界面，支持加、减、乘、除、平方、sin、cos等操作。你可以直接运行代码，查看计算器的界面效果，并进行数字运算。
