type object 'datetime.datetime' has no attribute 'datetime'
PythonDatetimeNamespacesPython Problem Overview
I have gotten the following error:
> type object 'datetime.datetime' has no attribute 'datetime'
On the following line:
date = datetime.datetime(int(year), int(month), 1)
Does anybody know the reason for the error?
I imported datetime with from datetime import datetime if that helps
Thanks
Python Solutions
Solution 1 - Python
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.
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)
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)
I suspect you or one of the modules you're using has imported like this:
from datetime import datetime.
Solution 2 - Python
For python 3.3
from datetime import datetime, timedelta
futuredate = datetime.now() + timedelta(days=10)
Solution 3 - Python
You should use
date = datetime(int(year), int(month), 1)
Or change
from datetime import datetime
to
import datetime
Solution 4 - Python
You should really import the module into its own alias.
import datetime as dt
my_datetime = dt.datetime(year, month, day)
The above has the following benefits over the other solutions:
- Calling the variable
my_datetimeinstead ofdatereduces confusion since there is already adatein the datetime module (datetime.date). - The module and the class (both called
datetime) do not shadow each other.
Solution 5 - Python
If you have used:
from datetime import datetime
Then simply write the code as:
date = datetime(int(year), int(month), 1)
But if you have used:
import datetime
then only you can write:
date = datetime.datetime(int(2005), int(5), 1)
Solution 6 - Python
I run into the same error maybe you have already imported the module by using only import datetime so change from datetime import datetime to only import datetime. It worked for me after I changed it back.
Solution 7 - Python
import time
import datetime
from datetime import date,timedelta
You must have imported datetime from datetime.
Solution 8 - Python
I found this to be a lot easier
from dateutil import relativedelta
relativedelta.relativedelta(end_time,start_time).seconds
Solution 9 - Python
from datetime import datetime
import time
from calendar import timegm
d = datetime.utcnow()
d = d.strftime("%Y-%m-%dT%H:%M:%S.%fZ")
utc_time = time.strptime(d,"%Y-%m-%dT%H:%M:%S.%fZ")
epoch_time = timegm(utc_time)
Solution 10 - Python
Avoid to write:
from datetime import datetime
datetime.datetime.function()
Solution No. 1:
import datetime
datetime.datetime.function()
Solution No. 2:
from datetime import datetime
datetime.function()
