It raises an exception because there's no such module as 'urllib2' in
Python 3.
You're reading the docs here:
https://docs.python.org/2/howto/urllib2.html
which are for Python 2, but the path you have here:
C:/Python34/import_web_data.py
says that you're using Python 3.4.
There's an explanation of Python 2 vs Python 3 here:
