date time in pyttho firsth lesson
what is the differ between datetime.datetime and datetime only? When I call dir on both, I get different results why this? I thought that when I wrote datetime.datetime I'm working on instance directly in implicit way avoiding of writing instance = datetime() and hence datetime.datetime is same instance.datetime. I'm more confuse I have a big headache , can anyone help me?

Hi Gaetano! I remember this confusing me when I first met
datetime. The difference is just a single
datetime refers to the library module
datetime and the other reference
datetime.datetime refers to the
datetime object within the module
datetime. In practice, this becomes:
import datetime # <-- import the module datetime # to see the object datetime, you need reference the module namespace datetime.datetime.now() # <-- run the 'now' method on the 'datetime' object from the 'datetime' namespace. Yikes!
Alternatively, you can import the datetime object and refer to it directly:
from datetime import datetime # <-- import the datetime object from the module datetime # Now you can refer to the object datetime directly because it is now in the local namespace datetime.now() # <-- run the 'now' method on the 'datetime' object directly
If using the latter example and then try to refer to
datetime.datetime you will get the error similar to:
AttributeError: type object 'datetime.datetime' has no attribute 'datetime'
