选项卡的动态填充

问：

我有一个可以更改的选项卡名称列表，因此我想遍历名称并创建选项卡。从这些按钮中，我想放置各种按钮，这些按钮根据用户单击的选项卡而有所不同。我的问题是我的选项卡无法加载。如果我删除该命令，我的窗口会使用正确的选项卡正常加载。

我的代码：

import tkinter as tk
from tkinter import ttk

def loadtab(event):
    selection = event.widget.select()
    tabN = event.widget.tab(selection, "text")
    t_nos=str(uFrame.index(uFrame.select())+1)
    tab = f'tab{t_nos}'

    if tabN == 'Ed':
        tk.Button(tab, text=tabN).pack()
    elif tabN == 'Ted':
        tk.Button(tab, text=tabN).pack()

root = tk.Tk()
root.title("Tab")

uFrame = ttk.Notebook(root, style="TFrame") #Create notebook
uFrame.pack(pady=20)
uFrame.bind("<<NotebookTabChanged>>", loadtab) #Bind notebook so that when it is changed, it loads items onto each tab

pathOpt = ['Ed', 'Ted'] #Tab names
tNo = 0 #Counter
for name in pathOpt: #parse through tab names and create tabs
    tab = f'tab{tNo + 1}'
    tab = ttk.Frame(uFrame)
    uFrame.add(tab, text=pathOpt[tNo])
    tNo += 1

test = tk.Button(root, text='Deliniate tabs') # placeholder to show where tabs are
test.pack(pady=20)
root.mainloop()

结果：

Exception in Tkinter callback
Traceback (most recent call last):

我已经打印了各种名称等，并发现选项卡名称是正确的，但我仍然收到错误。
