时间与格式不匹配'%a%b%d%H:

时间:2015-12-10 19:06:12

标签: python datetime datetime-format

尝试使用datetime模块时出现此错误

似乎它无法识别我的时间格式

文件中使用的时间格式如下:

2015年1月17日星期六21:20:41 +0000

有人知道导致这个问题的原因吗?谢谢!

指令time_str = str(f)正在将对象f转换为str。所以在你的情况下,time_str的值是&lt; _io.TextIOWrapper name ='time.txt'mode ='r'coding ='utf8'&gt;

您可能想要阅读该文件:

time_str = f.readline()
