Python is a very cool programming language that I've started learning. It's extremely powerful and I've already done some neat stuff with it. I wrote an interactive sales tax calculator for PA residents. (I'm working on a version that will let you tell me what state you are in and output the information appropriately.

# This is actually the cost of the item and the tax. This would be a ridiculous tax rate.
tax = 1.07
price = raw_input("How much is your item before tax? ")
totalcost = float(price) * float(tax)
finalanswer = round(totalcost, 2)
print finalanswer

Here's a screenshot of how it works:
