This repository contains solutions to various problems on Project Euler. They are mainly written in Python, but some problems may have been solved partially by hand or on a simple calculator.

The goal is to solve the maximum number of problems with the constraint that every solution should run in under 10s, preferably under 1s, using CPython or PyPy, whichever is faster on the particular script. A secondary goal is to create a reusable module of common functions used across multiple solutions (src/euler.py).
