If you are stuck with an exercise and want some help then you can email firstname.lastname@example.org and Zed will help you when he can. He's busy though writing more books, so be patient.
When you email, please write out the problem you are having, and make sure you have done each of the following first:
- Put a comment above each line of code explaining what it does to yourself.
- Compared your code to my code line-by-line from the last line to the first.
- Confirmed that every single letter, number, word, punctuation, and space is exactly like mine. Even the capitalization has to be the same so Print and print are two totally different things. To make them the same you would need them to both be print.
Once you've done that then email me for help and please include your code in the email or somewhere online so I can see it.
