I\'m trying to add n (integer) working days to a given date, the date addition has to avoid the holidays and weekends (it\'s not included in the working days)
This will take some work since there isn't any defined construct for holidays in any library (by my knowledge at least). You will need to create your own enumeration of those.
Checking for weekend days is done easily by calling .weekday() < 6 on your datetime object.
