使用python编写一个计算器 并打包成可执行文件

好的，我可以为你提供一个Python计算器的示例代码，并指导你如何将其打包成可执行文件。首先，我们使用Python的Tkinter模块来创建GUI界面，然后使用eval()函数计算用户输入的表达式。以下是示例代码：

import tkinter as tk

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

        # 创建输入框
        self.entry = tk.Entry(master, width=30, borderwidth=5)
        self.entry.grid(row=0, column=0, columnspan=4, padx=10, pady=10)

        # 创建数字按钮
        self.button_1 = tk.Button(master, text="1", padx=40, pady=20, command=lambda: self.button_click(1))
        self.button_2 = tk.Button(master, text="2", padx=40, pady=20, command=lambda: self.button_click(2))
        self.button_3 = tk.Button(master, text="3", padx=40, pady=20, command=lambda: self.button_click(3))
        self.button_4 = tk.Button(master, text="4", padx=40, pady=20, command=lambda: self.button_click(4))
        self.button_5 = tk.Button(master, text="5", padx=40, pady=20, command=lambda: self.button_click(5))
        self.button_6 = tk.Button(master, text="6", padx=40, pady=20, command=lambda: self.button_click(6))
        self.button_7 = tk.Button(master, text="7", padx=40, pady=20, command=lambda: self.button_click(7))
        self.button_8 = tk.Button(master, text="8", padx=40, pady=20, command=lambda: self.button_click(8))
        self.button_9 = tk.Button(master, text="9", padx=40, pady=20, command=lambda: self.button_click(9))
        self.button_0 = tk.Button(master, text="0", padx=40, pady=20, command=lambda: self.button_click(0))

        # 创建运算符按钮
        self.button_add = tk.Button(master, text="+", padx=39, pady=20, command=lambda: self.button_click("+"))
        self.button_subtract = tk.Button(master, text="-", padx=41, pady=20, command=lambda: self.button_click("-"))
        self.button_multiply = tk.Button(master, text="*", padx=40, pady=20, command=lambda: self.button_click("*"))
        self.button_divide = tk.Button(master, text="/", padx=41, pady=20, command=lambda: self.button_click("/"))
        self.button_equal = tk.Button(master, text="=", padx=91, pady=20, command=self.button_equal)
        self.button_clear = tk.Button(master, text="Clear", padx=79, pady=20, command=self.button_clear)

        # 将按钮放入界面
        self.button_1.grid(row=3, column=0)
        self.button_2.grid(row=3, column=1)
        self.button_3.grid(row=3, column=2)

        self.button_4.grid(row=2, column=0)
        self.button_5.grid(row=2, column=1)
        self.button_6.grid(row=2, column=2)

        self.button_7.grid(row=1, column=0)
        self.button_8.grid(row=1, column=1)
        self.button_9.grid(row=1, column=2)

        self.button_0.grid(row=4, column=0)

        self.button_clear.grid(row=4, column=1, columnspan=2)
        self.button_add.grid(row=5, column=0)
        self.button_subtract.grid(row=6, column=0)
        self.button_multiply.grid(row=6, column=1)
        self.button_divide.grid(row=6, column=2)

        self.button_equal.grid(row=5, column=1, columnspan=2)

    def button_click(self, number):
        current = self.entry.get()
        self.entry.delete(0, tk.END)
        self.entry.insert(0, str(current) + str(number))

    def button_clear(self):
        self.entry.delete(0, tk.END)

    def button_equal(self):
        expression = self.entry.get()
        result = eval(expression)
        self.entry.delete(0, tk.END)
        self.entry.insert(0, result)

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

在代码中，我们创建了一个Calculator类，该类包含了计算器的GUI界面和计算逻辑。我们使用grid函数将数字按钮和运算符按钮放置在GUI界面中。

然后我们通过创建一个Tk对象，并将其传递给Calculator类来显示计算器的GUI界面。

现在我们需要将这个Python脚本打包成可执行文件。我们可以使用pyinstaller库来完成这个任务。以下是打包步骤：

1. 安装pyinstaller库

在命令行中输入以下命令：

pip install pyinstaller

2. 打包Python脚本

在命令行中切换到Python脚本所在目录，并输入以下命令：

pyinstaller --onefile calculator.py

这将会在dist目录下生成一个可执行文件，名为calculator.exe。

现在你可以双击该可执行文件来运行计算器了。
