[已解决]有关tkinter里Radiobutton组件用法

长衫罩子龙

请问这段代码有什么错误吗？
import tkinter as tk

window = tk.Tk()
window.title('choice')
window.geometry('300x100')

v = tk.IntVar()
v.set(2)

tk.Radiobutton(window, text="One", variable=v, value=1).pack(anchor=W)
tk.Radiobutton(window, text="Two", variable=v, value=2).pack(anchor=W)
tk.Radiobutton(window, text="Three", variable=v, value=3).pack(anchor=W)


tk.mainloop()


这段让文本左靠齐的代码总是报错。。
tk.Radiobutton(window, text="One", variable=v, value=1).pack(anchor=W)

报错：
Traceback (most recent call last):
  File "D:/python/新建文件夹/小甲鱼练习题/Radiobutton.py", line 13, in <module>
    tk.Radiobutton(window, text="One", variable=v, value=1).pack(anchor=W)
NameError: name 'W' is not defined

请问如何解决？

W 是包含在 tkinter 包里的，所以要加上 tk.
