import datetime

def add100days(datestring):
     day, month, year = [int(x) for x in datestring.split('.')]
     date0 = datetime.date(year, month, day)
     date1 = date0 + datetime.timedelta(days=100)
     newdatestring = '%.2d.%.2d.%.4d' % (date1.day, date1.month,
         date1.year)
     return newdatestring


You may want to do the details differently, but datetime is the module 
that you want to use.
