This will change you into the right directory. <code>ls</code> | |||
will show you the source code files in that directory. One of the files is "<code>yelp1.py</code>", which has a "<code>.py</code>" extension indicating that it is a Python script. Type: | |||
python yelp1.py | |||
at the command prompt to execute the <code>yelp.py</code> Python script. Wait a little while while your computer connects to Yelp. You should see a series of pieces of yelp data run by your screen. If you don't, let a mentor know. | |||
