datetime - extract hour from timestamp with python -

i have dataframe df_energy2

df_energy2.info() <class 'pandas.core.frame.dataframe'> rangeindex: 29974 entries, 0 29973 data columns (total 4 columns): timestamp        29974 non-null datetime64[ns] p_act_kw         29974 non-null int64 periode_tarif    29974 non-null object p_souscr         29974 non-null int64 dtypes: datetime64[ns](1), int64(2), object(1) memory usage: 936.8+ kb 

with structure :

df_energy2.head()  timestamp p_act_kw periode_tarif p_souscr 2016-01-01 00:00:00 116 hc 250  2016-01-01 00:10:00 121 hc 250 

is there python fucntion can extract hour timestamp?

kind regards

i think need dt.hour:

print (df.timestamp.dt.hour) 0    0 1    0 name: timestamp, dtype: int64  df['hours'] = df.timestamp.dt.hour print (df)             timestamp  p_act_kw periode_tarif  p_souscr  hours 0 2016-01-01 00:00:00       116            hc       250      0 1 2016-01-01 00:10:00       121            hc       250      0
