Answer 1

您必须将函数名称（不带括号）指定给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()
