We use passwords every day for our email and other computer accounts. How secure is the password that you use? How hard would it be for someone to guess your password? How hard is it to write a computer program to guess a password? You can see for yourself by writing a simple password guesser in the computer language Python. We will get you started with some ideas, a little sample code, and a few passwords for your computer program to try and guess.

Here's a project where you can try your hand at being a detective with your computer. In this project you'll write a program to do some basic analysis of features of written text (for example, counting the length of each word in the text, or the number of words in each sentence). Then you'll see if you can use the information from your text analysis program to find measurements that can distinguish one author from another. After analyzing known samples of several authors' writings, can your…
