+<h3>
+Setting up the PythonLearn Environment on a Macintosh
+</h3>
+<p>Python is already installed on Macintosh OS/X operating system so all you need to add
+is a programmer text editor.
+</p>
+<h3>Pre-Requisite: TextWrangler</h3>
+<p>Please download and install TextWrangler from this site.
+</p>
+<p><a href="http://www.barebones.com/products/TextWrangler/download.html" target="_new">http://www.barebones.com/products/TextWrangler/download.html</a>
+
+<p>
+<b>Important:</b> Before you create your first program, you need to make one small change in the
+Preferences for TextWrangler. This will save you lots of "Python indent errors" anguish later.
+Under <b> TextWrangler -> Preferences -> Editor Defaults</b> tick the check box
+for "Expand Tabs" and close the dialog box
+(<a href="textwrangler_tabs_prefs.png" target="_new">Screenshot</a>).
+
+<h3>Editing With TextWrangler</h3>
+<p>
+<b>Note:</b> We have a screen cast for the use of TextWrangler. You can either view this on
+<!-- Note to self - Vimeo cannot handle these files - so YouTube is what we get -->
+<a href="http://www.youtube.com/watch?v=et2vjUAz9-k" target="_new">YouTube</a> or you can
+download the high-quality
+<a href="http://www-personal.umich.edu/~csev/courses/shared/podcasts/mac-python-textwrangler.mov"
+target="_new">QuickTime version</a> of the screen cast.
+You will need Apple QuickTime installed to view this video.
+</p>
+<p>
+Go into the upper-right of your screen and click on the Spotlight search button and type <b>textwrangler</b>.
+
+<p>
+Then create your first Python program.
+<pre>
+ print "Hello World"
+</pre>
+<p>Save your program as firstprog.py onto your Desktop.
+You will notice that after you save the file, TextWrangler will color your code based on the Python syntax rules.
+Syntax coloring is a very helpful feature as it gives you visual feedback about your program and can help you track down syntax errors more easily. TextWrangler only knows that your file is a Python file after you save it with a ".py" suffix.
+</p>
+
+<h3>Running Python Using the Built-In TextWrangler Shortcut</h3>
+<p>
+TextWrangler has a built-in way to run a Python program directly from
+the TextWrangler user interface. In TextWrangler go to the menu item <b>#! -> Run in Terminal </b>
+<p>
+TextWrangler will bring up a terminal window and automatically execute Python on your program.
+You will have to look closely to pick out the output from your program amongst the rest of the output in the terminal window.
+<p>
+In general, you can use the TextWrangler shortcut for very simple programs but once you start
+reading and writing files in your Python programs you should open and use the terminal program
+so you know what directory your program is running in - so you can open and read files.
+
+<h3>Starting Terminal on Macintosh OS/X</h3>
+<p>
+The Terminal program on Macintosh is kind of buried under <b>Macintosh HD -> Applications -> Utilities -> Terminal</b>
+<p>
+There are several shortcuts that you might find helpful. You can go into the upper-right of
+your screen and click on the Spotlight search button and type
+<b>terminal</b> and you can execute Terminal from the pop-up
+list of items.
+<p>
+You can get Terminal to stay in your dock once terminal is launched by clicking and
+holding on the Terminal icon in the dock and then selecting Keep in Dock.
+Then you can quickly launch Terminal by clicking on the icon in the dock.
+
+<h3>Where Are You?</h3>
+<p>
+When the command line starts up, you are in your "home" directory.
+In each of these examples, your logged in account should be used instead of csev.
+<pre>
+ Macintosh Home Directory: /Users/csev
+</pre>
+The command line prompt usually includes some clue as to where you are at
+in the folder structure on your hard drive. If you want to really figure out
+where you are, on Macintosh use the <b>pwd</b> command.
+<pre>
+ udhcp-macvpn-624:~ csev$ pwd
+ /Users/csev
+ udhcp-macvpn-624:~ csev$
+</pre>
+
+<h3>Where can you go?</h3>
+<p>
+Generally the first thing you want to do when you open a command line
+interface is to navigate to the right folder. Say you wanted to run a file from your desktop. The command is
+<b>cd Desktop </b>
+<pre>
+ udhcp-macvpn-624:~ csev$ pwd
+ /Users/csev
+ udhcp-macvpn-624:~ csev$ cd Desktop
+ udhcp-macvpn-624:Desktop csev$ pwd
+ /Users/csev/Desktop
+ udhcp-macvpn-624:Desktop csev$
+</pre>
+Nifty Trick: On the cd command, you can partially type a folder name like Desktop
+and then press the TAB key and the system will auto-complete the folder name
+if you have typed enough that the system can accurately guess what you mean to type.
+<p>
+Going Backwards (or Upwards)
+<p>
+You can change directory to the parent folder (the folder "above" the folder you
+are in using the <b>cd ..</b> command. It just says "go up one".
+<pre>
+ udhcp-macvpn-624:Desktop csev$ pwd
+ /Users/csev/Desktop
+ udhcp-macvpn-624:Desktop csev$ cd ..
+ udhcp-macvpn-624:~ csev$ pwd
+ /Users/csev
+ udhcp-macvpn-624:~ csev$
+</pre>
+If you get Lost...
+<p>
+If you can't figure out what folder you are in and/or cannot figure
+out how to get to the folder you want to get to "home" simply close and
+re-open the Command Line / Terminal window.
+<p>
+What Files/Folders are Here?
+<p>
+You can list the contents of the current directory using the <b>ls -l</b> command.
+<pre>
+ udhcp-macvpn-624:Desktop csev$ pwd
+ /Users/csev/Desktop
+ udhcp-macvpn-624:Desktop csev$ ls -l
+ total 8
+ -rw-r--r-- 1 csev staff 15 Sep 16 15:17 firstprog.py
+ udhcp-macvpn-624:Desktop csev$
+</pre>
+Running Your Python Program in the Terminal
+<p>
+Start the Terminal program, navigate to the proper directory and type the following command:
+<pre>
+ python firstprog.py
+</pre>
+This loads the Python interpreter and runs <b>firstprog.py</b>, showing the program output and/or errors
+in the Terminal window.
+<p>
+Some Cool Hints on The Macintosh Terminal Program
+<p>
+You can scroll back through previous commands by pressing the up and down arrows and re-execute
+commands using the enter key. This can save a lot of typing.
+If you like keeping your screen uncluttered, you can clear the scroll
+back buffer by pressing the Command key and the K key at the same time.

+Editing and Running Python Programs on the Rasberry Pi
+</h3>
+<p>
+The <a href="http://www.raspberrypi.org" target="_new">Raspberry Pi</a> is a low-cost ($5 to $35US) complete Linux computer. It is a great platform for writing
+Python programs and learning about computers in general.
+</p>
+<p>
+We won't cover getting a RasPi up and running here - but the nice thing is that
+once it is up and running there is nothing else needed to develop the
+programs for this class.
+</p>
+<h3>Writing "Hello World" on the Raspberry Pi</h3>
+<p>
+You can either view screen cast for these instructions on
+<a href="http://www.youtube.com/watch?v=wfX8NRCeX3A" target="_new">YouTube</a> or you can
+download the high-quality
+<a href="http://www-personal.umich.edu/~csev/courses/shared/podcasts/raspi-hello-world.mp4"
+target="_new">MP4 version</a> of the screen cast.
+You will need Apple QuickTime or some other MP4 viewer
+installed to view this video. The quality is much higher and the
+details are easier to read on the MP4 version.
+</p>
+<p>
+Go to the lower-right of your screen and click on the Start icon and then
+go to <b> Accessories -> Leafpad</b>. Leafpad is the text editor.
+</p>
+<p>
+Then create your first Python program.
+<pre>
+ print "Hello World"
+</pre>
+<p>Save your program as firstprog.py onto your Desktop.
+
+<h3>Starting Terminal </h3>
+<p>
+While there are many ways to run a Python program under Linux, we will prefer
+using the terminal program.
+There are several terminal programs on the Raspian Linux - my favourite is at
+</p>
+<b>Start -> Accessories -> LXTerminal</b>
+</p>
+LXTerminal has a nice preferences feature to allow you to change the
+size and color of the text.
+<h3>Where Are You?</h3>
+<p>
+When LXTerminal starts up, you are in your "home" directory.
+In each of these examples, your logged in account should be used
+instead of csev.
+<pre>
+ Home Directory: /home/csev
+</pre>
+The command line prompt usually includes some clue as to where you are at
+in the folder structure on your hard drive. If you want to really figure out
+where you are, on Linux use the <b>pwd</b> command.
+<pre>
+ csev@rasberrypi:~$ pwd
+ /home/csev
+ csev@rasberrypi:~$
+</pre>
+
+<h3>Where can you go?</h3>
+<p>
+Generally the first thing you want to do when you open a terminal program
+is to navigate to the correct folder.
+Say you wanted to run a file from your Desktop. The command is
+<b>cd Desktop </b>
+<pre>
+ csev@rasberrypi:~$ pwd
+ /home/csev
+ csev@rasberrypi:~$ cd Desktop
+ csev@rasberrypi:~$ pwd
+ /home/csev/Desktop
+ csev@rasberrypi:~$
+</pre>
+Nifty Trick: On the cd command, you can partially type a folder
+name like Desktop
+and then press the TAB key and the system will auto-complete
+the folder name if you have typed enough that the system can
+accurately guess what you mean to type.
+<p>
+Going Backwards (or Upwards)
+<p>
+You can change directory to the parent folder
+(the folder "above" the folder you
+are in using the <b>cd ..</b> command. It just says "go up one".
+<pre>
+ csev@rasberrypi:~$ pwd
+ /home/csev/Desktop
+ csev@rasberrypi:~$ cd ..
+ csev@rasberrypi:~$ pwd
+ /home/csev
+ csev@rasberrypi:~$
+</pre>
+If you get Lost...
+<p>
+If you can't figure out what folder you are in and/or cannot figure
+out how to get to the folder you want to get to "home" simply close and
+re-open the Command Line / Terminal window.
+<p>
+What Files/Folders are Here?
+<p>
+You can list the contents of the current directory using the <b>ls -l</b> command.

+ csev@rasberrypi:~$ ls -l
+ total 4
+ -rw-r--r-- 1 csev csev 15 Jan 9 15:17 firstprog.py
+ csev@rasberrypi:~$
+</pre>
+<h3>Running Your Python Program in the Terminal</h3>

+<pre>
+ csev@rasberrypi:~$ python firstprog.py
