	Google PageRank matrix calculator (graphically) - 19^th of May 2004 Some time ago I wrote about the Google PageRank algorithm in Python. It's a matrix algorithm for calculating the PageRank values for every page in a web. All you have to do is define which pages links to which and the algorithm calculates the PageRanks for every page for you.
	Google as calculator - 31^st of August 2003 This is cool: You can now use Google as a calculator.
	Calculator in Python for dummies - 17^th of December 2007 I need a mini calculator in my web app so that people can enter basic mathematical expressions instead of having to work it out themselfs and then enter the result in the input box. I want them to be able to enter "32" or "110/3" without having to do the math first. I want this to work like a pocket calculator such that `110/3` returns a `36.6666666667` and not `36` like pure Python arithmetic would. Here's the solution which works but works like Python: def safe_eval(expr, symbols={}): return eval(expr, dict(__builtins__=None), symbols) def calc(expr): return safe_eval(expr, vars(math)) assert calc('32')==6 assert calc('12.12 + 3.75 - 10*0.5')==10.87 assert calc('110/3')==36
