python - Taking the difference between two dates using pandas? -

-

i trying take time difference between 2 dates using pandas , having trouble.

the format dates in follows:

2016/07/06 03:10:39

using pandas.to_datetime can these datetime64 type cannot figure out way take difference of these types.

here basis of code:

df2.end = to_datetime(df1.end) df2.start = to_datetime(df1.start)

if print these objects dataframe here get:

series([], name: end, dtype: datetime64[ns]) series([], name: start, dtype: datetime64[ns])

end:

0    2016-07-06 04:39:16 1    2016-07-06 04:13:30 2    2016-07-06 03:51:30

start

0    2016-07-06 05:01:14 1    2016-07-06 04:39:06 2    2016-07-06 04:13:27

i have tried following:

df2.difference = df2.end-df2.start

and following error:

typeerror: ufunc subtract cannot use operands types dtype('<m8[ns]') , dtype('o')

that's work perfectly:

>>> import pandas >>> x = pandas.to_datetime("2016/07/06 03:10:39") >>> y = pandas.to_datetime("2016/07/06 03:11:21") >>> y-x timedelta('0 days 00:00:42')
