这段代码中存在语法错误。第一行的import语句和第二行的from语句之间需要添加一个换行符，否则会报错。将这两行代码修改为如下形式即可：

import tkinter as tk
from tkinter import filedialog
from common import LayoutCenter

class EditForm:
    def __init__(self, master):
        self.master = master
        LayoutCenter(master, "修订评分标准")
        # 创建滚动条
        vsb = tk.Scrollbar(master, orient=tk.VERTICAL)
        vsb.pack(side="right", fill="y")

        # 创建文本框并关联滚动条
        self.text = tk.Text(self.master, yscrollcommand=vsb.set)
        self.text.pack(fill="y", expand=True)
        vsb.config(command=self.text.yview)

        self.create_menu()

        self.text.bind("<KeyRelease>", self.update_line_numbers)
        self.text.tag_configure("line_numbers", justify="right")

    # 添加行号标记
    def update_line_numbers(self,event=None):
        self.text.delete("line_numbers")
        for i, line in enumerate(self.text.get("1.0", "end").split("\n")):
            self.text.insert(f"{i+1}.0", f"{i+1}\n", "line_numbers")

    def create_menu(self):
        menu = tk.Menu(self.master)
        self.master.config(menu=menu)

        file_menu = tk.Menu(menu)
        menu.add_cascade(label="File", menu=file_menu)
        file_menu.add_command(label="Open", command=self.open_file)
        file_menu.add_command(label="Save", command=self.save_file)
        file_menu.add_separator()
        file_menu.add_command(label="Exit", command=self.exit)

    def open_file(self):
        file_path = filedialog.askopenfilename()
        if file_path:
            with open(file_path, "r") as file:
                self.text.delete("1.0", "end")
                self.text.insert("1.0", file.read())

    def save_file(self):
        file_path = filedialog.asksaveasfilename()
        if file_path:
            with open(file_path, "w") as file:
                file.write(self.text.get("1.0", "end"))

    def exit(self):
        self.master.destroy()

    def run(self):
        self.master.mainloop()

root = tk.Tk()
my_gui = EditForm(root)
my_gui.run()

请注意，我还将root.mainloop()替换为my_gui.run()，这样可以避免在运行时出现多个Tkinter窗口的问题。
