Convert datetime.datetime object to days since epoch in Python
Question: I've got a `pandas.Series` object that might look like this:

    
    
    import pandas as pd
    myVar = pd.Series(["VLADIVOSTOK 690090", "MAHE", NaN, NaN, "VLADIVOSTOK 690090", "2000-07-01 00:00:00"])
    

`myVar[5]` is parsed as a `datetime.datetime` object when the data is read
into Python via `pandas`. I'm assuming that converting this value to the
number of days since epoch (36708) isn't difficult at all. I'm just new to
Python and don't know how to do it. Thanks in advance!


Answer: I'm not sure where you're getting 36,708 days since the epoch (it's only been
16,644 days since January 1, 1970), but `datetime.timedelta` objects (used in
date arithmetic) have a `days` attribute:

    
    
    >>> import datetime
    >>> (datetime.datetime.utcnow() - datetime.datetime(1970,1,1)).days
    16644
