Python 日期时间 strptime() 和 strftime() : how to preserve the timezone information

见以下代码:importdatetimeimportpytzfmt='%Y-%m-%d%H:%M:%S%Z'd=datetime.datetime.now(pytz.timezone("America/New_York"))d_string=d.strftime(fmt)d2=datetime.datetime.strptime(d_string,fmt)printd_stringprintd2.strftime(fmt)输出是2013-02-0717:42:31EST2013-02-0717:42:31时区信息只是在翻译中丢失了。如果我将'%Z'切换到'%z',我会得到ValueEr
