Answer 1

I think you 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
