Chicago Python Workshop/Chicago Python Workshop 1/Friday/Linux project dependencies

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/BostonPythonWorkshop6/Twitter/httplib2-0.6.0.zip
 * http://mit.edu/jesstess/www/BostonPythonWorkshop6/Twitter/simplejson-2.1.6.zip
 * http://mit.edu/jesstess/www/BostonPythonWorkshop6/Twitter/python-twitter.zip
 * http://mit.edu/jesstess/www/BostonPythonWorkshop6/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 /home/jesstess/Desktop/httplib2-0.6.0,

cd /home/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:

sudo python setup.py install

type in your password, and hit enter to install httplib2.

Navigate to the 3 other dependency directories and run

sudo python setup.py install

in all of them to install those dependencies as well.

If you get an error like:

ImportError: No module named setuptools

you need an extra package. Type:

sudo apt-get install python-setuptools

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/BostonPythonWorkshop6/Twitter.tar.gz
 * 3) Find Twitter.tar.gz on your Desktop and double-click on it to "extract" 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 /home/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 see 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.

State Capitals
We'll look at an example Python script that quizzes you on state capitals 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) * http://web.mit.edu/jesstess/www/BostonPythonWorkshop6/state_capitals.py

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