是pandas.timestamp python datetime吗？

Question

I was working on time submodule of astropy. It can parse python datetime objects.

When I pass a pandas.Timestamp object astropy.time.Time thinks it's a datetime object.

Tracking down the issue, I found this.

>>> t = pandas.Timestamp('2018-01-01')
>>> isinstance(t, datetime.datetime)
True

My question is, why is isinstance returning True ?

Answer 1

because it inherits from datetime.datetime

class _Timestamp(__datetime.datetime):

so it is an instance of a datetime.datetime ...

Answer 2

TimeStamp is the pandas equivalent of python's Datetime and is interchangable with it in most cases.

See pandas.Timestamp documentation
