时间不匹配格式 '%a %b %d %H:

Question

我在尝试使用日期时间模块时遇到此错误

好像不认识我的时间格式

文件中使用的时间格式如下：

1 月 17 日星期六 21:20:41+0000 2015

有谁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 <_io.TextIOWrapper name='time.txt' mode='r' encoding='utf8'>

您可能想改为阅读该文件：

time_str = f.readline()

时间不匹配格式 '%a %b %d %H:

time does not match format '%a %b %d %H:

python

datetime
