AttributeError: 'Series' object has no attribute 'days'

I have a column 'delta' in a dataframe dtype: timedelta64[ns], calculated by subcontracting one date from another. I am trying to return the number of days as a float by using this code:

from datetime import datetime
from datetime import date
df['days'] = float(df['delta'].days)

but I receive this error:

AttributeError: 'Series' object has no attribute 'days'

Any ideas why?

Solution

  • While subtracting the dates you should use the following code.

    df = pd.DataFrame([ pd.Timestamp('20010101'), pd.Timestamp('20040605') ])
(df.loc[0]-df.loc[1]).astype('timedelta64[D]')

    So basically use .astype('timedelta64[D]') on the subtracted column.
