===Download and extract the Twitter project dependencies===
 
<ol>
<li>Click and save these four dependencies to your Desktop:
* 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
</li>
<li>
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.
</li>
</ol>
 
===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,
 
<pre>
cd /home/jesstess/Desktop/httplib2-0.6.0
</pre>
 
will change you into that directory, and
 
<pre>
ls
</pre>
 
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:
 
<pre>
sudo python setup.py install
</pre>
 
type in your password, and hit enter to install httplib2.
 
Navigate to the 3 other dependency directories and run
 
<pre>
sudo python setup.py install
</pre>
 
in all of them to install those dependencies as well.
 
If you get an error like:
 
<pre>
ImportError: No module named setuptools
</pre>
 
you need an extra package. Type:
 
<pre>
sudo apt-get install python-setuptools
</pre>
 
===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:
 
# Right click the following file, click "Save Target as..." or "Save link as...", and save it to your Desktop directory:
#* https://github.com/downloads/aishahalim/TwitterAPI/Twitter.tar.gz
#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 <code>/home/jesstess/Desktop/Twitter</code>,
 
<pre>
cd /home/jesstess/Desktop/Twitter
</pre>
 
will change you into that directory, and
 
<pre>
ls
</pre>
 
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:
 
<pre>
python twitter_api.py --search=python
</pre>
 
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.
 
# Right click the following file, click "Save Target as..." or "Save link as...", and save it to your Desktop directory:
#* http://web.mit.edu/jesstess/www/BostonPythonWorkshop6/state_capitals.py
 
==Success!==
 
You are done installing dependencies for the Saturday projects.
