AttributeError:'unicode'对象没有属性'sleep'

Question

我得到了AttributeError:'unicode'对象没有在这个问题的标题中指定的属性'sleep',我无法弄清楚为什么它会抛出该错误消息.这是自动发布facebook的自动脚本.如果有人知道我的代码有什么问题,我告诉我.代码在这里

Answer 1

这是因为你用下面一行的字符串覆盖了时间

tim=elem.find_element_by_css_selector('._5ptz.timestamp.livetimestamp')
time=tim.text
if time=='Just now':

所以时间不再是一个模块,它只是一个unicode文本.您需要将该变量重命名为其他内容
