python脚本补充
本文是对实用的 Python 小脚本_python写脚本-CSDN博客的一点补充。对简单脚本的一些操作上的优化。
###Utilities
###
###重命名文件名
import os
import tkinter as tk
from tkinter import filedialog, simpledialog, messageboxdef batch_rename():# 弹出文件夹选择对话框directory = filedialog.askdirectory()if not directory:return# 弹出输入对话框让用户输入前缀prefix = simpledialog.askstring("输入前缀", "请输入文件名前缀:")if not prefix:returntry:for count, filename in enumerate(os.listdir(directory)):dst = f"{prefix}{str(count)}.txt"src = os.path.join(directory, filename)dst = os.path.join(directory, dst)os.rename(src, dst)# 命名完成，弹出成功提示框messagebox.showinfo("完成", "文件重命名完成！")except Exception as e:# 出现错误，弹出错误提示框messagebox.showerror("错误", f"重命名过程中出现错误: {e}")#finally:# 关闭主窗口，结束程序#root.destroy()# 创建主窗口
# root = tk.Tk()
# root.withdraw() # 隐藏主窗口
#
# # 调用重命名函数
# batch_rename()
#
# # 进入主事件循环
# root.mainloop()###
