>I'm telling Python to import because it doesn't exist and it throws an error.  I don't get it; I just don't get it.  If I'm working with R, I can import thousands of libraries with no errors whatsoever.  With Python, I just get thousands of errors with nothing working whatsoever.  I totally don't understand this language.  Import means import.  Right.  WTF!!!!!

	Well, you are using Python 3.4 -- there were significant changes made
in the transition from 2.x to 3.x. 90% of the stuff you find on the web is
probably written against Python 2.x -- if the example uses

	print "some stuff %s" % ("or other",)
if is 2.x, while

	print("some stuff %s" % ("or other",))
if could be 2.x (the extra () don't affect 2.x print statement) but is more
likely to be 3.x (though 3.x likely is also using a different formatter
than the old % string interpolation).

	The best documentation is the supplied help system -- the library
reference manual in particular. Glancing at that would reveal that 3.x does
not have a urllib2 module (and the documentation in 2.7.5 even states:
"""
Note
The urllib2 module has been split across several modules in Python 3 named
urllib.request and urllib.error. The 2to3 tool will automatically adapt
imports when converting your sources to Python 3.
