===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.
