Why does this python script work on Ubuntu but not Raspbian?

Question

A friend and I created the following script utilizing BeautifulSoup to get the HTML of a job page, then append the job to an array, then a file, then email the job in a human-readable format to ourselves. The script works on Ubuntu, but on my Raspberry Pi, which uses Raspbian, it doesn't work.

The only message I see when running from the terminal is: 'end of file' and 'Start write...' which are lines in the code. There are no error messages when running from the Pi, but nothing gets appended to the array and no emails are sent.

Can someone take a look? Thanks.
