如何在python tkinter中运行当前打开的文件？

from tkinter import Tk, filedialog

root = Tk()

file_path = filedialog.askopenfilename()

if file_path:
    # 打开文件并进行相应的操作
    with open(file_path, 'r') as file:
        # 在这里可以对文件进行读取、处理等操作
        file_contents = file.read()
        print(file_contents)
else:
    print("未选择文件")

from tkinter import Tk, filedialog

root = Tk()
file_path = filedialog.askopenfilename()

if file_path:
    with open(file_path, 'r') as file:
        file_contents = file.read()
        print(file_contents)
else:
    print("未选择文件")
