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:
