Montreal Python Workshop/Friday/OSX project dependencies

Download the ColorWall project
You'll be writing graphical effects for an existing ColorWall project. Download this ColorWall code and example effects so you're ready to start working with them tomorrow:


 * 1) Right click the following file, click "Save Target as..." or "Save link as...", and sav)e it to your Desktop directory:
 * 2) * http://jvns.ca/MontrealPythonWorkshop3/ColorWall.zip
 * 3) The ".zip" extension on the above file indicates that it is a compressed Zip archive. You may need to "extract" its contents. To do this, find ColorWall.zip on your Desktop and double-click on it. That will create a folder called ColorWall containing several files. (Note: your browser might do this for you automatically.)

Test the ColorWall code
Start a command prompt and navigate to the Desktop/ColorWall directory where the ColorWall code lives. For example, if the ColorWall project is at ,

cd /home/jesstess/Desktop/ColorWall

will change you into that directory (the "~" means your home directory!), and

ls

will show you the source code files in that directory. One of the files is "run.py", which has a ".py" extension indicating that it is a Python script. Type:

python run.py

at the command prompt to execute the run.py Python script. You should see a window pop up and start cycling through colorful effects. If you don't, let a staff member know.

Now type:

python run.py -a -s

at the command prompt to execute the run.py Python script so that it runs only the advanced effects. You should see a window pop up and start cycling through different colorful effects. If you don't, let a staff member know.

You can also run both sets of effects by typing:

python run.py -a

Success!
You've completed setup for the ColorWall project.

Download the Wordplay project
We've written some skeleton code for the Wordplay project already. Download this code so you're ready to start working with it tomorrow:


 * 1) Right click the following file, click "Save Target as..." or "Save link as...", and save it to your Desktop directory:
 * 2) * http://web.mit.edu/jesstess/www/BostonPythonWorkshop7/Wordplay.zip
 * 3) Find Wordplay.zip on your Desktop and double-click on it to "unzip" it. That will create a folder called Wordplay containing several files.

Test the Wordplay code
Start a command prompt and navigate to the Desktop/Wordplay directory where the Wordplay code lives. For example, if the Wordplay project is at ,

cd /Users/jesstess/Desktop/Wordplay

will change you into that directory, and

ls

will show you the source code files in that directory. One of the files is "words1.py", which has a ".py" extension indicating that it is a Python script. Type:

python words1.py

at the command prompt to execute the words1.py Python script. You should see a column of English words printed to the screen. If you don't, let a staff member know.

Success!
You've completed setup for the Wordplay project.

Download and extract the Twitter project dependencies
 Click and save these four dependencies to your Desktop:   The ".zip" extension on the above files indicates that they are compressed Zip archives. We need to "extract" their contents. To do this, double-click on each file. This will create a directory for each file, containing the source code for the dependency.  
 * http://mit.edu/jesstess/www/BostonPythonWorkshop7/Twitter/httplib2-0.6.0.zip
 * http://mit.edu/jesstess/www/BostonPythonWorkshop7/Twitter/simplejson-2.1.6.zip
 * http://mit.edu/jesstess/www/BostonPythonWorkshop7/Twitter/python-twitter.zip
 * http://mit.edu/jesstess/www/BostonPythonWorkshop7/Twitter/python-oauth2.zip

Install the Twitter project dependencies
Each of these 4 dependencies has an installer script that we'll need to run at a command prompt to install the software. It is important that the dependencies are installed in the order listed above. For each project, start a command prompt and navigate to the Desktop directory where the source code lives. For example, if the httplib2-0.6.0 project was extracted to /Users/jesstess/Desktop/httplib2-0.6.0,

cd /Users/jesstess/Desktop/httplib2-0.6.0

will change you into that directory, and

ls

will show you the source code files in that directory. One of the files is "setup.py", which has a ".py" extension indicating that it is a Python script. Type:

python setup.py install --user

and hit enter to install httplib2. You will need to enter your Mac account password.

If you see some warning while installing, that's fine -- the software is still installing successfully.

Navigate to the 3 other dependency directories and run

python setup.py install --user

in all of them to install those dependencies as well.

Download the Twitter project
We've written some skeleton code for the Twitter project already. Download this code so you're ready to start working with it tomorrow:


 * 1) Right click the following file, click "Save Target as..." or "Save link as...", and save it to your Desktop directory:
 * 2) * http://web.mit.edu/jesstess/www/BostonPythonWorkshop7/Twitter.zip
 * 3) Find Twitter.zip on your Desktop and double-click on it to "unzip" it. That will create a folder called Twitter containing several files.

Test the Twitter code
Start a command prompt and navigate to the Desktop/Twitter directory where the Twitter code lives. For example, if the Twitter project is at ,

cd /Users/jesstess/Desktop/Twitter

will change you into that directory, and

ls

will show you the source code files in that directory. One of the files is "twitter_api.py", which has a ".py" extension indicating that it is a Python script. Type:

python twitter_api.py --search=python

at the command prompt to execute the twitter_api.py Python script. You should the text from 20 tweets containing the word "Python" printed to the screen. If you don't, let a staff member know.

Success!
You've completed setup for the Twitter project.

Capital Cities
We'll look at an example Python script that quizzes you on capital cities during the lecture on Saturday.


 * 1) Right click the following file, click "Save Target as..." or "Save link as...", and save it to your Desktop directory:
 * 2) * https://raw.github.com/jvns/mtlpytutorial/master/capitals.py

Success!
You are done installing dependencies for the Saturday projects.
