Sentinel is a simple framework for insurance related pricing. Sentinel allows you to write your insurance product frameworks in pure Python. No additional packages or modules required.
# Standard Library Imports
import csv
# Sentinel Imports
from sentinelpricing import Framework
class Motor(Framework):
"""A Fake Motor Insurance Product...
...with very simple pricing.
"""
def load_rating_file(self, path):
with open(path) as f:
reader = csv.DictReader(f)
table = LookupTable(reader, name=path)
return table
def set_up(self):
"""Load rating tables into the framework"""
self.age = load_rating_file("age_rates.csv")
self.lic = load_rating_file("lic_rates.csv")
def calculation(self, quote):
"""Quote Calculation"""
# Imagine a base rate of £/$150
quote += 150
# Multiply that by the age rating factor
quote *= self.age[quote['age']]
# Multiply that by the license years rating factor
quote *= self.lic[quote['lic']]
# Return the finished quote
return quote
# Returns a Quote object from the Motor Framework.
Motor.quote(
{"age": 34, "lic": 7}
)With a few lines of code, you are ready to use Sentinel to start building pricing engines for analysis, or rating engines ready for deployment. Python is the most popular language in the world (as of 2024), now you can use it and all its features to bring your work to the next level.
Sentinel is available on PyPi, albeit with a slightly different name:
$ python -m pip install sentinelpricing
Sentinel officially supports Python 3.11+.
Whilst in alpha development, features are expected to be added as and when - so keep checking!
- Framework Inheritance
- Audit Trails for Quote Calculations
- Lookup Tables for Rates
- Helpful Data Handling
Note, the Sentinel Package should never require third-party libraries. You'll have enough of an argument with your IT department to just get Python installed - If they get wind of having to download dependencies you'll never hear the end of it.
