[FIXED] How to substract two dates based on filter of two other columns

Issue

I am new in Python and I am struggling to reshape my dataFrame.

For a particular client (contact_id), I want to add an new date column that actually substracts the DTHR_OPERATION date for a 'TYPE_OPER_VALIDATION = 3' minus the DTHR_OPERATION date for a 'TYPE_OPER_VALIDATION = 1'.
If the 'TYPE_OPER_VALIDATION' is equal to 3 and that there is less than a hour difference between those two dates, I want to add a string such as 'connection' for example in the new column.

I have an issue "python Series' object has no attribute 'total_seconds" when I try to compare if the time difference is indeed minus or equal to an hour. I tried many solutions I found on Internet but I always seem to have a data type issue.

Here is my code snippet:

df_oper_one = merged_table.loc[(merged_table['TYPE_OPER_VALIDATION']==1),['contact_id','TYPE_OPER_VALIDATION','DTHR_OPERATION']]
df_oper_three = merged_table.loc[(merged_table['TYPE_OPER_VALIDATION']==3),['contact_id','TYPE_OPER_VALIDATION','DTHR_OPERATION']]

connection = []
for row in merged_table['contact_id']:
    if (df_validation.loc[(df_validation['TYPE_OPER_VALIDATION']==3)]) & ((pd.to_datetime(df_oper_three['DTHR_OPERATION'],format='%Y-%m-%d %H:%M:%S') - pd.to_datetime(df_oper_one['DTHR_OPERATION'],format='%Y-%m-%d %H:%M:%S').total_seconds()) <= 3600): connection.append('connection')
     # if diff_date.total_seconds() <= 3600: connection.append('connection')
    else:  connection.append('null')

merged_table['connection'] = pd.Series(connection)

Solution

sure, here is the information you are looking for :

The desired result is a dF5 with the following columns [['contact_id', 'fullname', 'validation_id', 'LIBEL_LONG_PRODUIT_TITRE', 'TYPE_OPER_VALIDATION']] as well as this new colum dF5['connection]. Don't hestitate to reach out if you need further information or clarifications. Many thanks for your support :)
