我想将此字符串 datetimestring ='Fri，08 Jun 2012 22:40:26 GMT'使用python转换为时间戳。

I want to convert this string datetimestring = 'Fri, 08 Jun 2012 22:40:26 GMT' to timestamp using python.

我尝试了

timestamp = time.mktime(time.strptime(datetimestring, '%a, %d %B %Y %H:%M:%S GMT'))

但报告正则表达式错误。

but reports regex error.

推荐答案

您正在使用％B ，它对应于完整的月份名称，但只有缩写名称。您应该改用％b ：

You're using %B, which corresponds to the full month name, but you only have the abbreviated name. You should use %b instead:

>>> import time >>> datetimestring = 'Fri, 08 Jun 2012 22:40:26 GMT' >>> timestamp = time.mktime(time.strptime(datetimestring, '%a, %d %B %Y %H:%M:%S GMT')) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/_strptime.py", line 454, in _strptime_time return _strptime(data_string, format)[0] File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/_strptime.py", line 325, in _strptime (data_string, format)) ValueError: time data 'Fri, 08 Jun 2012 22:40:26 GMT' does not match format '%a, %d %B %Y %H:%M:%S GMT' >>> timestamp = time.mktime(time.strptime(datetimestring, '%a, %d %b %Y %H:%M:%S GMT')) >>> timestamp 1339209626.0
