Question

我有一段代码，目前在我的本地python（anaconda python 3.5.1）上运行没有任何问题，但是当我在生产中运行它时给我一个奇怪的错误（我的印象是环境非常类似，python版本是相同的。）

以下是相关的代码段：

ds_date_format = "%Y%m%d"
rta_date_format = '%a %b %d %H:%M:%S %Z %Y'

d1 = datetime.datetime.strptime(date_ds, ds_date_format)
d2 = datetime.datetime.strptime(date_rta, rta_date_format).replace(hour=0, minute=0, second=0)

我得到的错误的追溯。

    ],
    "code": 500,
    "message": "Internal Server Error"
  }
}

该值错误似乎很奇怪，因为据我所知，指定的格式是正确的。

正如M.T所指出的，strptime（）和时区似乎存在问题。按如下方式重写我的代码实现了我期望的结果：

from dateutil.parser import parse    
...
d1 = parse(date_ds)
d2 = parse(date_rta)
...

时间数据格式不匹配错误
