You can use PyAstronomy which has https://pyastronomy.readthedocs.io/en/latest/pyaslDoc/aslDoc/decimalYear.html#PyAstronomy.pyasl.decimalYear

pip install PyAstronomy

Then:

In [1]: from PyAstronomy import pyasl

In [2]: import datetime as dt

In [3]: d = dt.datetime(2010,9,2,0,0,0)

In [4]: pyasl.decimalYear(d)
Out[4]: 2010.668493150685
