帮我编写一个拥有精美图形界面的科学计算器python程序

可以使用 GUI 库如 tkinter 来编写一个拥有精美图形界面的科学计算器。

以下是一个使用 tkinter 编写的简单科学计算器的示例代码：

import tkinter as tk
from math import pi, e, sin, cos, tan, log10, log, sqrt

class Calculator:
    def __init__(self, master):
        self.master = master
        master.title("科学计算器")

        self.result = tk.StringVar()
        self.result.set("0")
        self.result_label = tk.Label(master, textvariable=self.result, font=("Arial", 16), anchor="e")
        self.result_label.grid(row=0, column=0, columnspan=4, padx=10, pady=10, ipady=10, sticky="we")

        self.create_buttons()

    def create_buttons(self):
        values = [
            ["π", "e", "x!", "C"],
            ["7", "8", "9", "/"],
            ["4", "5", "6", "*"],
            ["1", "2", "3", "-"],
            ["0", ".", "=", "+"],
        ]

        for i, value_list in enumerate(values):
            for j, value in enumerate(value_list):
                if value == "=":
                    btn = tk.Button(self.master, text=value, font=("Arial", 16), command=self.calculate)
                elif value == "C":
                    btn = tk.Button(self.master, text=value, font=("Arial", 16), command=self.clear)
                else:
                    btn = tk.Button(self.master, text=value, font=("Arial", 16), command=lambda x=value: self.insert(x))
                btn.grid(row=i + 1, column=j, padx=10, pady=10)

    def clear(self):
        self.result.set("0")

    def insert(self, value):
        current = self.result.get()
        if current == "0":
            self.result.set(value)
        else:
            self.result.set(current + value)

    def calculate(self):
        expression = self.result.get()
        try:
            self.result.set(eval(expression))
        except:
            self.result.set("Error")

root = tk.Tk()
app = Calculator(root)
root.mainloop()

使用这段代码，你可以创建一个简单的科学计算器。然而
