While it's not what the original author is intending, it seems to me
that dynamically adding fields could be useful when something like a
database schema changed frequently. For example, a row in a database
might contain data related to a customer and I would think it might be
useful to do something like this (where data is a dictionary created
from the column names and row data):
class Customer:
def __init__(self, data):
for col_name, value in data.iteritems():
setattr(self, col_name, value)
Alternatively, you could just assign the original dictionary to a
field on Customer called data and then access it by key:
class Customer:
def __init__(self, data):
self.customerData = data
I'm pretty new to Python so it's entirely possible I'm doing things
the hard way but if you had behavior on a class, I can see where
dynamically creating fields on it would be useful.
