python - 属性错误 : 'unicode' object has no attribute 'sleep'

Question

我收到 AttributeError: 'unicode' object has no attribute 'sleep' as specified in this question 并且我无法弄清楚为什么它会抛出该错误消息。这是将自动发布 facebook 的自动化脚本。如果有人知道我的代码有什么问题，请告诉我。代码在这里

Answer 1

这是因为你在下一行用字符串覆盖了时间

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名称
