Answer 1

你必須指定函數名（無括號）至command=

import tkinter as tk 
import webbrowser 

# --- functions --- 

def google_search(): 
    new = 2 

    # get user input 
    term = user_input.get() 

    tabUrl = "http://google.com/?#q=" 
    webbrowser.open(tabUrl+term, new=new); 

# --- main --- 

root = tk.Tk() 

lbl = tk.Label(text="GhostTest") 
lbl.pack() 

user_input = tk.Entry(bd=2) 
user_input.pack() 

# run `google_search` on button click 
btn = tk.Button(text="Search", command=google_search) 
btn.pack() 

root.mainloop()
