About the Author
Albert Sweigart (but you can call him Al), is a software developer in San Francisco, California
who enjoys haunting coffee shops and making useful software. Hacking Secret Ciphers with
Python is his third book.
His first two books, Invent Your Own Computer Games with Python and Making Games with
Python & Pygame can be read online for free at http://inventwithpython.com.
He is originally from Houston, Texas. He laughs out loud when watching park squirrels, which
makes people think he’s a simpleton.
