Fifty solutions in sixteen months

Observant readers (both of you) will notice a graphic has just popped up in the sidebar of this blog. This should update automatically to reflect my Project Euler progress.

And, yes, after 16 months I have finally solved the first 50 problems.

I have to admit that some of my solutions are a little slower than they should be, but I am quite pleased to have made it this far and it is quite nice to be able to see the extent to which my Python is improving.
