如何在Tkinter中返回控制台输出的字符串值以放入标签中

import tkinter as tk

root = tk.Tk()

output_text = tk.Text(root, height=10, width=40, state='disabled')
output_text.pack()

scrollbar = tk.Scrollbar(root)
scrollbar.pack(side='right', fill='y')

output_text.config(yscrollcommand=scrollbar.set)
scrollbar.config(command=output_text.yview)

import sys

def capture_console_output():
    console_output = sys.stdout.getvalue()
    output_text.config(state='normal')
    output_text.delete('1.0', 'end')
    output_text.insert('end', console_output)
    output_text.config(state='disabled')

# 将标准输出重定向到字符串
sys.stdout = tk.StringVar()
sys.stdout.set('')

button = tk.Button(root, text='获取控制台输出', command=capture_console_output)
button.pack()

import tkinter as tk
import sys

root = tk.Tk()

output_text = tk.Text(root, height=10, width=40, state='disabled')
output_text.pack()

scrollbar = tk.Scrollbar(root)
scrollbar.pack(side='right', fill='y')

output_text.config(yscrollcommand=scrollbar.set)
scrollbar.config(command=output_text.yview)

def capture_console_output():
    console_output = sys.stdout.getvalue()
    output_text.config(state='normal')
    output_text.delete('1.0', 'end')
    output_text.insert('end', console_output)
    output_text.config(state='disabled')

sys.stdout = tk.StringVar()
sys.stdout.set('')

button = tk.Button(root, text='获取控制台输出', command=capture_console_output)
button.pack()

root.mainloop()
