## Chapter 1, A Taste of Py

1.1 If you don’t already have Python 3 installed on your computer, do it now. Read Appendix D for the details for your computer system.

1.2 Start the Python 3 interactive interpreter. Again, details are in Appendix D. It should print a few lines about itself and then a single line starting with >>>. That’s your prompt to type Python commands.

Here’s what it looks like on my MacBook Pro:

````\$` `python`
`Python` `3.3``.``0` `(``v3``.``3.0``:``bd8afb90ebf2``,` `Sep` `29` `2012``,` `01``:``25``:``11``)`
`[``GCC` `4.2``.``1` `(``Apple` `Inc``.` `build` `5666``)` `(``dot` `3``)]` `on` `darwin`
`Type` `"help"``,` `"copyright"``,` `"credits"` `or` `"license"` `for` `more` `information``.`
`>>>````

1.3 Play with the interpreter a little. Use it like a calculator and type this: `8 * 9`. Press the Enter key to see the result. Python should print 72.

````>>>` `8` `*` `9`
`72````

1.4 Type the number `47` and press the Enter key. Did it print 47 for you on the next line?

````>>>` `47`
`47````

1.5 Now type `print(47)` and press Enter. Did that also print 47 for you on the next line?

````>>>` `print``(``47``)`
`47````

## Chapter 2, Py Ingredients: Numbers, Strings, and Variables

2.1 How many seconds are in an hour? Use the interactive interpreter as a calculator and multiply the number of seconds in a minute (60) by the number of minutes in an hour (also 60).

````>>>` `60` `*` `60`
`3600````

2.2 Assign the result from the previous task (seconds in an hour) to a variable called `seconds_per_hour`.

````>>>` `seconds_per_hour` `=` `60` `*` `60`
`>>>` `seconds_per_hour`
`3600````

2.3 How many seconds are in a day? Use your `seconds_per_hour` variable.

``>>>` `seconds_per_hour ...``
