您只需要弹出一个窗口来输入详细信息，那么就试试这个：

import tkinter as tk
from tkinter import simpledialog, messagebox
import numpy as np

root = tk.Tk() #creating a tcl interpreter
root.withdraw() #hiding the window
entry = simpledialog.askstring('Input Popup', 'Enter the numbers separated by commas') #creating a pop up window

try:
    lst = [int(x) for x in entry.split(',')]
    print(np.array(lst)) #print the array of it out.
except (AttributeError,ValueError):
    messagebox.showerror('Invalid input','Enter an proper valid input') #to show error message in a window
finally:
    root.destroy() #destroying the window finally

我已经用注解解释了代码，以便在运行中理解，但请记住，用户必须以1，2，3，4（逗号分隔格式）的形式输入。
