[問題] Tkinter裡的Label用法問題
請問一下
Label它的textvariable變數沒辦法在迴全裡變動嗎?
def abc():
for i in range(1,20):
msgbottom_var.set(str(i))
time.sleep(0.3)
msg = tk.Label(app, font=global_font, textvariable = msgbottom_var)
msg.place( height=30,x=10,y=310)
submit = tk.Button(app, font=global_font, text = "送出", command = abc)
submit.place( height=30,x=200,y=310)
按送出時只有到19才顯示出來
是什麼原因?
