使用wxPython和pandas模块生成Excel文件的代码实现

pip install wxPythonpip install pandas

import wx
import os
import pandas as pd

class MyFrame(wx.Frame):
    def __init__(self, parent, title):
        super(MyFrame, self).__init__(parent, title=title, size=(400, 200))
        
        panel = wx.Panel(self)
        
        self.output_dir_btn = wx.Button(panel, label="选择输出文件夹")
        self.Bind(wx.EVT_BUTTON, self.on_select_output_dir, self.output_dir_btn)
        
        self.input_file_btn = wx.Button(panel, label="选择Excel文件")
        self.Bind(wx.EVT_BUTTON, self.on_select_input_file, self.input_file_btn)
        
        self.start_btn = wx.Button(panel, label="开始生成")
        self.Bind(wx.EVT_BUTTON, self.on_start_generation, self.start_btn)
        
        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(self.output_dir_btn, 0, wx.ALL|wx.EXPAND, 5)
        sizer.Add(self.input_file_btn, 0, wx.ALL|wx.EXPAND, 5)
        sizer.Add(self.start_btn, 0, wx.ALL|wx.EXPAND, 5)
        panel.SetSizer(sizer)
        
    def on_select_output_dir(self, event):
        dlg = wx.DirDialog(self, "选择输出文件夹", style=wx.DD_DEFAULT_STYLE)
        if dlg.ShowModal() == wx.ID_OK:
            self.output_dir = dlg.GetPath()
            print("输出文件夹:", self.output_dir)
        dlg.Destroy()
    
    def on_select_input_file(self, event):
        dlg = wx.FileDialog(self, "选择Excel文件", wildcard="Excel files (*.xlsx)|*.xlsx",
                            style=wx.FD_OPEN | wx.FD_FILE_MUST_EXIST)
        if dlg.ShowModal() == wx.ID_OK:
            self.input_file = dlg.GetPath()
            print("输入文件:", self.input_file)
        dlg.Destroy()
    
    def on_start_generation(self, event):
        if not hasattr(self, 'output_dir') or not hasattr(self, 'input_file'):
            wx.MessageBox("请先选择输出文件夹和Excel文件", "错误", wx.OK | wx.ICON_ERROR)
            return
        
        df = pd.read_excel(self.input_file)
        
        for i, col in enumerate(df.iloc[:, 0]):
            column_names = col.split(',')
            file_name = f"{i+1}.xlsx"
            file_path = os.path.join(self.output_dir, file_name)
            
            df_new = pd.DataFrame(columns=column_names)
            df_new.to_excel(file_path, index=False)
        
        wx.MessageBox("生成完成", "提示", wx.OK | wx.ICON_INFORMATION)
        self.Close()

app = wx.App()
frame = MyFrame(None, "Excel文件生成器")
frame.Show()
app.MainLoop()```

在上述代码中，我们创建了一个`MyFrame`类，继承自wxPython的`Frame`类。该类表示我们的应用程序窗口，并包含了选择输出文件夹和选择Excel文件的按钮。

**3. 实现回调函数**

接下来，我们需要实现与按钮关联的回调函数。这些函数将在用户点击相应的按钮时被调用。

```python
    def on_select_output_dir(self, event):
        dlg = wx.DirDialog(self, "选择输出文件夹", style=wx.DD_DEFAULT_STYLE)
        if dlg.ShowModal() == wx.ID_OK:
            self.output_dir = dlg.GetPath()
            print("输出文件夹:", self.output_dir)
        dlg.Destroy()
    
    def on_select_input_file(self, event):
        dlg = wx.FileDialog(self, "选择Excel文件", wildcard="Excel files (*.xlsx)|*.xlsx",
                            style=wx.FD_OPEN | wx.FD_FILE_MUST_EXIST)
        if dlg.ShowModal() == wx.ID_OK:
            self.input_file = dlg.GetPath()
            print("输入文件:", self.input_file)
        dlg.Destroy()
    
    def on_start_generation(self, event):
        if not hasattr(self, 'output_dir') or not hasattr(self, 'input_file'):
            wx.MessageBox("请先选择输出文件夹和Excel文件", "错误", wx.OK | wx.ICON_ERROR)
            return
        
        df = pd.read_excel(self.input_file)
        
        for i, col in enumerate(df.iloc[:, 0]):
            column_names = col.split(',')
            file_name = f"{i+1}.xlsx"
            file_path = os.path.join(self.output_dir, file_name)
            
            df_new = pd.DataFrame(columns=column_names)
            df_new.to_excel(file_path, index=False)
        
        wx.MessageBox("生成完成", "提示", wx.OK | wx.ICON_INFORMATION)
        self.Close()

app = wx.App()
frame = MyFrame(None, "Excel文件生成器")
frame.Show()
app.MainLoop()
