python调试问题
from tkinter import *
from tkinter.messagebox import *

class app:
  def __init__(self):
   
  self.lb = Label(text='Hello World !', fg='red')
  self.lb.pack()
  self.scc = Scale(from_=10,to=40,orient=HORIZONTAL)
  self.scc.set(40)
  self.scc.pack(fill=X, expand=1)
  self.scc.bind('<Button-1>',self.resize())
   
  def resize(self):
  self.lb.config(text='%d' % self.scc.get())
  showinfo('ss')


if __name__ == "__main__":
  root = Tk()
  root.minsize(600,600)
  roots = app()
  root.mainloop()

为什么每次运行都会自动执行按钮的点击（也就是resize会自动执行，根本不用手动去点击），之后再手动点击按钮就没有反映了，请高手帮忙
