"Project Euler is a series of challenging mathematical/computer programming problems that will require more than just mathematical insights to solve. Although mathematics will help you arrive at elegant and efficient methods, the use of a computer and programming skills will be required to solve most problems."
Python
I will be working through various problem from the Project Euler website to improve my coding skills in Python. The problems are designed to test a combination of maths and computer science skills.
