使用tkinter 和 pandas两个库，以及class方法来编写股权稀释计算器

以下是一个简单的股权稀释计算器，使用了tkinter和pandas两个库，并使用了class方法来实现：

import tkinter as tk
import pandas as pd

class DilutionCalculator:
    def __init__(self, initial_shares, new_shares, options, warrants):
        self.initial_shares = initial_shares
        self.new_shares = new_shares
        self.options = options
        self.warrants = warrants

    def calculate(self):
        diluted_shares = self.initial_shares + self.new_shares + self.options + self.warrants
        ownership = (self.initial_shares / diluted_shares) * 100
        return diluted_shares, ownership

class App:
    def __init__(self, master):
        self.master = master
        self.master.title("股权稀释计算器")

        # 创建输入框和标签
        tk.Label(master, text="初始股数：").grid(row=0, column=0)
        self.initial_shares_entry = tk.Entry(master)
        self.initial_shares_entry.grid(row=0, column=1)

        tk.Label(master, text="新股数：").grid(row=1, column=0)
        self.new_shares_entry = tk.Entry(master)
        self.new_shares_entry.grid(row=1, column=1)

        tk.Label(master, text="期权数：").grid(row=2, column=0)
        self.options_entry = tk.Entry(master)
        self.options_entry.grid(row=2, column=1)

        tk.Label(master, text="认股证数：").grid(row=3, column=0)
        self.warrants_entry = tk.Entry(master)
        self.warrants_entry.grid(row=3, column=1)

        # 创建计算按钮
        self.calculate_button = tk.Button(master, text="计算", command=self.calculate)
        self.calculate_button.grid(row=4, column=0, columnspan=2)

        # 创建输出框和标签
        tk.Label(master, text="股权稀释后的总股数：").grid(row=5, column=0)
        self.diluted_shares_label = tk.Label(master, text="")
        self.diluted_shares_label.grid(row=5, column=1)

        tk.Label(master, text="股权稀释后的初始股权比例：").grid(row=6, column=0)
        self.ownership_label = tk.Label(master, text="")
        self.ownership_label.grid(row=6, column=1)

    def calculate(self):
        # 读取输入框中的值
        initial_shares = float(self.initial_shares_entry.get())
        new_shares = float(self.new_shares_entry.get())
        options = float(self.options_entry.get())
        warrants = float(self.warrants_entry.get())

        # 使用DilutionCalculator计算结果
        calculator = DilutionCalculator(initial_shares, new_shares, options, warrants)
        diluted_shares, ownership = calculator.calculate()

        # 更新输出标签的值
        self.diluted_shares_label.config(text="{:.2f}".format(diluted_shares))
        self.ownership_label.config(text="{:.2f}%".format(ownership))

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

代码中的DilutionCalculator类包含初始股数、新股数、期权数和认股证数等参数，并实现了calculate方法来计算股权稀释后的总股数和初始股权比例。

App类是一个简单的GUI程序，包含四个输入框和一个计算按钮，并使用DilutionCalculator类来计算结果，并将结果更新到两个输出标签中。
