===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 installUnzip the software. '''It is important that the dependencies are installed in thefile orderyou listedjust abovedownloaded.''' For each project, startOpen a command prompt and navigate to the Desktop directory where the source codeunzipped livesfolder. For example, if theyou httplib2-0.6.0extracted projectthe was extractedfolder to /home/jesstessmyname/Desktop/httplib2PythonWorkshop-0.6.0Twitter-master, the command
 
<pre>
cd /home/jesstessmyname/Desktop/httplib2PythonWorkshop-0.6.0Twitter-master
</pre>
 
will changemove you into that directory, and

will show you the source code files in that directory. In this directory are five folders: Twitter (the main folder) and four dependency folders (simplejson-3.3.0, python-oauth2-master, httplib2-0.8, and python-twitter-1.0). Three of the dependency subfolders have an installer script that we'll need to run at a command prompt to install the software. For each dependency (in the order: simplejson-3.3.0 python-oauth2-master httplib2-0.8) navigate to the folder using cd. For example:
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>
cd simplejson-3.3.0

To return to this main folder, use the cd command again to move up one directory:
Navigate to the 3 other dependency directories and run▼
 
<pre>
cd ..

Now use cd to move into the python-twitter-1.0 folder. This time we will run the two following commands to install the dependency:
===Download the Twitter project===
<pre>
python setup.py build
sudo python setup.py install
</pre>
 
And type in your password when prompted.
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:
#* http://web.mit.edu/jesstess/www/BostonPythonWorkshop6/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===
 
Within the python-twitter-1.0 folder, run
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>
python twitter_test.py
cd /home/jesstess/Desktop/Twitter
</pre>
 
After it runs, it should state that it ran 41 tests on the code, and the final line should say "OK." If your test failed, ask an instructor for help.

After successfully testing the dependencies, use the cd command again to navigate to the Twitter folder. Use the ls command again to view the files in this folder. One of the files is "twitter_functions.py", which has a ".py" extension indicating that it is a Python script. Open this file in your text editor and find the line that says:
<pre>
CONSUMER_SECRET = 'We will give this to you in class :)'
ls
</pre>
 
Change the string to the consumer secret string that we will give you in class. Save the file and go back to the command line. Now type:
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:
