Python 创建一个带有保存和加载功能的 HTML 文件生成器

在本文中，我们将介绍如何使用 Python创建一个简单的 GUI 应用程序，该程序允许用户选择保存路径、创建文件夹、输入 HTML 代码并将其保存为 HTML 文件。我们还将添加保存和加载设置的功能，使得用户可以在不同的会话之间保持配置。
C:\pythoncode\new\htmlcodesavetolocalfile.py

结果如下

1.  安装 wxPython

首先，我们需要 安装 wxPython 库。你可以使用 pip 来安装：

pip install wxPython

2. 创建基本框架

我们将创建一个基本的 Python应用程序框架，包括一个主窗口和一些基本的 UI 元素，如按钮和文本框。

import wx
import os
import xml.etree.ElementTree as ET
import datetimeclass MyApp(wx.App):def OnInit(self):self.frame = MyFrame(None, title="HTML File Generator")self.frame.Show()return Trueclass MyFrame(wx.Frame):def __init__(self, parent, title):super().__init__(parent, title=title, size=(600, 400))panel = wx.Panel(self)vbox = wx.BoxSizer(wx.VERTICAL)# Path selectionhbox1 = wx.BoxSizer(wx.HORIZONTAL)self.path_txt = wx.TextCtrl(panel)path_btn = wx.Button(panel, label="选择")path_btn.Bind(wx.EVT_BUTTON, self.on_select_path)hbox1.Add(self.path_txt, proportion=1, flag=wx.EXPAND|wx.ALL, border=5)hbox1.Add(path_btn, flag=wx.EXPAND|wx.ALL, border=5)# Folder name inputhbox2 = wx.BoxSizer(wx.HORIZONTAL)self.folder_txt = wx.TextCtrl(panel, style=wx.TE_CENTER)create_folder_btn = wx.Button(panel, label="创建")create_folder_btn.Bind(wx.EVT_BUTTON, self.on_create_folder)hbox2.Add(self.folder_txt, proportion=1, flag=wx.EXPAND|wx.ALL, border=5)hbox2.Add(create_folder_btn, flag=wx.EXPAND|wx.ALL, border=5)# HTML code inputhbox3 = wx.BoxSizer(wx.HORIZONTAL)self.html_txt = wx.TextCtrl(panel, style=wx.TE_MULTILINE)hbox3.Add(self.html_txt, proportion=1, flag=wx.EXPAND|wx.ALL, border=5)# HTML file name inputhbox4 = wx.BoxSizer(wx.HORIZONTAL)self.html_filename_txt = wx.TextCtrl(panel, style=wx.TE_CENTER)save_html_btn = wx.Button(panel, label="保存")save_html_btn.Bind(wx.EVT_BUTTON, self.on_save_html)hbox4.Add(self.html_filename_txt, proportion=1, flag=wx.EXPAND|wx.ALL, border=5)hbox4.Add(save_html_btn, flag=wx.EXPAND|wx.ALL, border=5)# Batch record selectionhbox5 = wx.BoxSizer(wx.HORIZONTAL)self.batch_choice = wx.Choice(panel)load_batch_btn = wx.Button(panel, label="加载记录")load_batch_btn.Bind(wx.EVT_BUTTON, self.on_load_batch)hbox5.Add(self.batch_choice, proportion=1, flag=wx.EXPAND|wx.ALL, border=5)hbox5.Add(load_batch_btn, flag=wx.EXPAND|wx.ALL, border=5)# Save settings buttonhbox6 = wx.BoxSizer(wx.HORIZONTAL)save_settings_btn = wx.Button(panel, label="保存设置")save_settings_btn.Bind(wx.EVT_BUTTON, self.on_save_settings)hbox6.Add(save_settings_btn, flag=wx.EXPAND|wx.ALL, border=5)vbox.Add(hbox1, flag=wx.EXPAND)vbox.Add(hbox2, flag=wx.EXPAND)vbox.Add(hbox3, proportion=1, flag=wx.EXPAND)vbox.Add(hbox4, flag=wx.EXPAND)vbox.Add(hbox5, flag=wx.EXPAND)vbox.Add(hbox6, flag=wx.EXPAND)panel.SetSizer(vbox)self.Bind(wx.EVT_SHOW, self.on_show)def on_select_path(self, event):with wx.DirDialog(self, "选择保存路径", style=wx.DD_DEFAULT_STYLE) as dialog:if dialog.ShowModal() == wx.ID_OK:self.path_txt.SetValue(dialog.GetPath())def on_create_folder(self, event):path = self.path_txt.GetValue()folder_name = self.folder_txt.GetValue()if path and folder_name:full_path = os.path.join(path, folder_name)os.makedirs(full_path, exist_ok=True)wx.MessageBox(f"文件夹 {folder_name} 创建成功", "提示", wx.OK | wx.ICON_INFORMATION)else:wx.MessageBox("请先选择保存路径并输入文件夹名称", "错误", wx.OK | wx.ICON_ERROR)def on_save_html(self, event):path = self.path_txt.GetValue()folder_name = self.folder_txt.GetValue()html_code = self.html_txt.GetValue()html_filename = self.html_filename_txt.GetValue() + ".html"if path and folder_name and html_code and html_filename:full_path = os.path.join(path, folder_name, html_filename)with open(full_path, "w", encoding="utf-8") as file:file.write(html_code)wx.MessageBox(f"HTML 文件 {html_filename} 保存成功", "提示", wx.OK | wx.ICON_INFORMATION)else:wx.MessageBox("请确保所有输入框都已填满", "错误", wx.OK | wx.ICON_ERROR)def on_load_batch(self, event):batch_name = self.batch_choice.GetStringSelection()if batch_name:tree = ET.parse('settings.xml')root = tree.getroot()batch = root.find(f"batch[@name='{batch_name}']")if batch is not None:self.path_txt.SetValue(batch.find('path').text)self.folder_txt.SetValue(batch.find('folder').text)self.html_txt.SetValue(batch.find('html').text)self.html_filename_txt.SetValue(batch.find('filename').text)def on_save_settings(self, event):self.save_settings()def save_settings(self):path = self.path_txt.GetValue()folder_name = self.folder_txt.GetValue()html_code = self.html_txt.GetValue()html_filename = self.html_filename_txt.GetValue()batch_name = datetime.datetime.now().strftime("%Y%m%d%H%M%S")if os.path.exists("settings.xml"):tree = ET.parse("settings.xml")root = tree.getroot()else:root = ET.Element("settings")batch = ET.SubElement(root, "batch", name=batch_name)ET.SubElement(batch, "path").text = pathET.SubElement(batch, "folder").text = folder_nameET.SubElement(batch, "html").text = html_codeET.SubElement(batch, "filename").text = html_filenametree = ET.ElementTree(root)tree.write("settings.xml", encoding="utf-8", xml_declaration=True)wx.MessageBox("设置已保存", "提示", wx.OK | wx.ICON_INFORMATION)self.update_batch_choice()def update_batch_choice(self):if os.path.exists("settings.xml"):tree = ET.parse("settings.xml")root = tree.getroot()batch_names = [batch.attrib['name'] for batch in root.findall('batch')]self.batch_choice.Clear()self.batch_choice.AppendItems(batch_names)def on_show(self, event):self.update_batch_choice()if __name__ == "__main__":app = MyApp()app.MainLoop()

3. 代码说明

1. 初始化应用程序和主窗口：创建 wxPython 应用程序和主窗口，其中包括所有 UI 元素。
2. 选择保存路径：使用 wx.DirDialog 来选择保存路径，并将路径显示在文本框中。
3. 创建文件夹：根据用户输入的文件夹名称，在选定路径下创建新文件夹。
4. 保存 HTML 文件：根据用户输入的 HTML 代码和文件名，将 HTML 文件保存在选定路径和文件夹下。
5. 保存设置：在保存设置按钮点击事件中，将当前配置保存到 settings.xml 文件中。
6. 加载批次：从 settings.xml 文件中加载保存的配置，并更新下拉框中的选项。
7. 显示时更新批次选项：在窗口显示时，调用 update_batch_choice 方法，确保下拉框中的选项是最新的。

4. 运行应用程序

保存上述代码到一个 Python 文件中，然后运行该文件。你将看到一个带有多个输入框和按钮的 GUI 应用程序。你可以选择保存路径、创建文件夹、输入 HTML 代码并保存为 HTML 文件。此外，你可以保存当前设置并在下次启动应用程序时加载之前的配置。
