类型对象'datetime.datetime'没有属性'datetime' [英] type object 'datetime.datetime' has no attribute 'datetime'

问题描述

我正在执行一个django教程，我收到以下错误：

I'm following a django tutorial, and I have gotten the following error:

类型对象'datetime.datetime'没有属性'datetime'

type object 'datetime.datetime' has no attribute 'datetime'

在下列行：

date = datetime.datetime(int(year), int(month), 1)

有没有人知道错误的原因？

Does anybody know the reason for the error?

我从datetime import datetime 导入datetime与如果帮助

I imported datetime with from datetime import datetime if that helps

感谢

推荐答案

Datetime是一个允许处理的模块的日期，时间和数据时间（所有这些都是数据类型）。这意味着 datetime 既是顶级模块，也是该模块中的一种类型。这是令人困惑的。

Datetime is a module that allows for handling of dates, times and datetimes (all of which are datatypes). This means that datetime is both a top-level module as well as being a type within that module. This is confusing.

您的错误可能基于模块的混乱命名，您或您正在使用的模块已导入。 >

Your error is probably based on the confusing naming of the module, and what either you or a module you're using has already imported.

>>> import datetime
>>> datetime
<module 'datetime' from '/usr/lib/python2.6/lib-dynload/datetime.so'>
>>> datetime.datetime(2001,5,1)
datetime.datetime(2001, 5, 1, 0, 0)

但是，如果您导入datetime.datetime：

But, if you import datetime.datetime:

>>> from datetime import datetime
>>> datetime
<type 'datetime.datetime'>
>>> datetime.datetime(2001,5,1) # You shouldn't expect this to work 
                                # as you imported the type, not the module
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: type object 'datetime.datetime' has no attribute 'datetime'
>>> datetime(2001,5,1)
datetime.datetime(2001, 5, 1, 0, 0)

我怀疑您或您正在使用的其中一个模块导入如下：
from datetime import datetime 。

I suspect you or one of the modules you're using has imported like this: from datetime import datetime.
