How to dynamically assign values to class properties in Python?

How to dynamically assign values to class properties in Python?

I'm trying to do the following: After performing a regex group search, I'm
trying to assign the results to the class properties by a specific order.
the number of results from the regex search varies from 1-5 values.
class Classification():
def __init__(self, Entry):
self.Entry = Entry
self.Section = ''
self.Class = 'Null'
self.Subclass = 'Null'
self.Group = 'Null'
self.Subgroup = 'Null'
def ParseSymbol(self,regex):
Properties_Pointers =
[self.Section,self.Class,self.Subclass,self.Group,self.Subgroup]
Pattern_groups = re.search(regex, self.Symbol)
i = 0
for group in Pattern_groups.groups():
Properties_Pointers[i] = group
i += 1
the problem is that for each loop iteration, instead of the class
property, Properties_Pointers[i] gets the property's value (and of course
in this case I can't assign the desired value to the property).
thanks.
