When choosing a web framework, I pretty much have eyes set on Tornado. But I heard good things about Flask and Gevent. So I tested the performance of each and combinations of the three. I chose something just a little more advanced than a "Hello World" program to write - one that use templates. Here are the codes:

1, Pure Flask (pure_flask.py)

Starting out with Competitive Programming

(This guide is meant for beginners. If you have solved 100+ problems and are looking for guidance on how to solve problems involving algorithms and data structures, this document is not for you.)

Competitive Programming is an interesting activity which mixes problem solving with programming. It is not only enjoyable but also very demanded in placements. Competitive programming will make you very good at writing efficient programs quickly.

	# Hello, and welcome to makefile basics.
	#
	# You will learn why `make` is so great, and why, despite its "weird" syntax,
	# it is actually a highly expressive, efficient, and powerful way to build
	# programs.

	# Once you're done here, go to

	# to learn SOOOO much more.
