如何将Python 3.11代码转换为Python 2.7并修复运行错误

问题分析与修改要点 #

原脚本在Python2.7中报错，核心是Python3与Python2的语法、API差异，具体修改如下：

• Tkinter模块导入：Python2中模块名为Tkinter（大写T），替换原小写tkinter导入
• 字符串格式化：移除Python3.6+专属的f-string，改用.format()方法实现路径拼接
• 组件父窗口指定：Python2中Tkinter组件必须显式绑定父窗口，修正Entry组件的创建方式
• 命名冲突修复：避免按钮变量名与submit函数重名，防止函数被覆盖
• 窗口图标兼容：Python2无iconphoto方法，改用Tcl命令实现图标设置（默认支持GIF/PGM/PPM格式，若用PNG需安装PIL库）
• 参数格式修正：os.path.exists不支持关键字参数path=，改为直接传参
• 退出逻辑替换：Python2中用sys.exit()替代exit()，需导入sys模块
• 回调函数修正：after()方法需传入函数对象，而非函数调用结果，移除update()后的括号

        except:
            # 图标加载失败时忽略，不影响主功能
            pass

        submit_btn = Button(window, text="开始", command=submit)
        submit_btn.place(y=130, x=120)
        submit_btn.config(bg='#111111', fg='white', font=('Arial', 13))

        e.place(relx=0.5, rely=0.5, anchor=CENTER)
        e.config(font=('Arial', 20), bg='#111111', fg='white')

        window.mainloop()

    except Exception:
        traceback.print_exc(file=log)

额外优化：将重复的文件夹创建逻辑用循环简化，减少冗余代码，提升可读性。
