Hi
I am using Python 3.4. I am trying to do some web scraping at this moment.
I got stuck because there is an IndexError: list index out of range if I
put stock_code = (18). My desire output is that the script is able to
detect print out the recent price whether it is up, down or unchanged.

Thank you for your response. I updated the first portion of my code to include

Short answer: always compare to None using `is` or `is not`.
Long answer:
If you want to check for src b

Express your intention in the code.
If you want to express “is this value the ‘None’ singleton?”, compare
identity with ‘is’/‘is not’. (This is what you almost always mean when
comparing to ‘N

Consider a 'send' method that sends a message to another system via a socket.
This method will wait for a response before returning. There are two possible
error conditions:
1) Timeout - i.e. no response received
2) Illegal response received
I need to communicate these errors

Yes, and Emile has shown how for a trivial, pure
binary case.
But to make the catenation sensible you need to know
the file type. Many media files hold the actual media
