Python code query The progress of Hong Kong-Macau Pass

Check the Python 3.3 code for the progress query for the Hong Kong and Macau Pass. Use the socket to request the relevant website, get the results and use the regular to find out the progress of processing. In fact, with URLLIB code will be more concise, but at that time is not familiar with urllib~

Directly on the code:
