from tkinter import ttk

root = Tk()
root.title("选择列表行")

scrollbar = Scrollbar(root)
scrollbar.pack(side=RIGHT, fill=Y)

listbox = Listbox(root, yscrollcommand=scrollbar.set)
listbox.pack(side=LEFT, fill=BOTH)

scrollbar.config(command=listbox.yview)

def select_row():
    selected_row = listbox.curselection()
    if selected_row:
        print("用户选择了第", selected_row[0]+1, "行")

button = Button(root, text="选择行", command=select_row)
button.pack()

root.mainloop()
