我正在处理一个python代码，它在facebook上接收新通知并将“m”发送到串口
（这是与PC连接的arduino）
在python监视器上，您可以编写电子邮件和密码登录到您的facebook 如果还没有新通知，则会显示“Zzz ...”。如果有新通知，显示器上会显示“Facebook上的新通知，提升标志......”。
登录Facebook并打印'Zzz ...'时效果很好。但问题是，即使我的脸书上有新的通知，代码也没有在屏幕上显示任何差异。

我认为从Facebook接收数据存在一些问题，来自代码：
while True and go:
try:
# br.reload ( )
# print br.response (). read ()
x = br.open ('http://m.facebook.com/home.php?refid=0').read ()
i = x.count ('< div class = "c"> ') # This field HTML is repeated more' than one time if there 'a new notification (before but' are read all notifications such events etc..).
except:
print "Delay in charge the page, wait 3 seconds applied .. \ n "
time.sleep(3)
if i>= 1:
notification = True # Notifications to read
else:
i = 0 #No notification
notification = False
