Simulator
Explore checksum techniques by calculating addition, XOR-based, and Fletcher checksums on data sets to understand how these methods help ensure data integrity and error detection. This lesson guides you through using a Python simulator to practice checksum computations on both random and custom data.

The program checksum.py is very simple: it can be used to calculate checksums
of different flavors (addition, XOR-based, or fletcher) on either random
values (as generated by the program) or on values you pass in as a series of
bytes.
