#79187 — Import Doesn't Import

So sorry everyone.  I've posted here several times today.  This is VERY frustrating.

So, I'm reading this link.
https://docs.python.org/2/howto/urllib2.html


Fetching URLs
The simplest way to use urllib2 is as follows:
import urllib2
response = urllib2.urlopen('http://python.org/')
html = response.read()


So, I fire up Python, and create a new file and name it and hit F5.

All I have is thins in the file:
import urllib2
response = urllib2.urlopen('http://python.org/')
html = response.read()

It immediately produces this error:
Traceback (most recent call last):
  File "C:/Python34/import_web_data.py", line 1, in <module>
    import urllib2
ImportError: No module named 'urllib2'


ImportError: No module named 'urllib2'
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!!!!!

Either this is the most brilliant thing ever invented, or it's the biggest piece of shit ever invented.  I just can't tell.  All I know for sure, is that it doesn't do ANYTHING that I tell it to do.  

If there is another way of running Python code, like using Visual Studio, or a text file, or some such thing, let me know, and I'll do it.  It seems like you should use Python to run Python, but my Python doesn't do anything at all.  Yesterday I uninstalled Python 2.7, because that wouldn't do anything either.  I'm just about ready to uninstall 3.4.

Maybe you should decide whether you want to run your 2.x code on 2.7,
or adapt it to 3.x.  Doing both won't work well, unless you go with a
version of the code carefully constructed to work on both.

I believe I heard there's a way of doing Python in Visual Studio, but
personally, I use Python on Linux without an IDE - mostly via a vim
macro.

BTW, I got your code to run, but it got stuck in a socket.recv(); I
suspect Wikipedia is blocking some forms of access, so this labor may
be irrelevant.

Perhaps check out
https://pypi.python.org/pypi?%3Aaction=search&term=stock&submit=search
, and use the most relevant-looking one with a matching version of
Python?

Perhaps you are trying too hard too fast.  When I started Python, after
20 years of on and off experience with multiple languages, I went
through the tutorial (on Dos, no Idle).  It took about 2 hours. Then I
quickly wrote the code I needed for a paid project.

Do stick with 3.4.2, but use the 3.4.2 manual.

Definitely not.  It is possible that Python will never fit your brain. 
But give it a bit more of a chance.

Because you have told it to do things like run a program with syntax 
error, or import something that does not exist.  I don't know of any 
language than does that ;-).

Yes, but import from where? If you ask Python - or any other language
- to "import asfadgt4tfihavzcxvzxcvaerg", do you expect it to succeed?
It doesn't exist.

In this case, you simply want "urllib", not "urllib2". You should be
able to "import urllib" with no problems.

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:

Note that this is the documentation for Python 2, which is obsolescent.
It has had a long life, so references to Python on the web are still
dominantly about that legacy version. Your confusion is quite normal.

Instead, use Python 3 only (which it seems you are doing), and read the
Python 3 documentation. You'll find that the ‘urllib’ modules
<URL:https://docs.python.org/3/library/urllib.html> are what you want.

> I don't get it; I just don't get it.

It's unfortunate that a lot of new Python users will be confused by this
long transition. But the situation is a lot better now; more and more
Python articles on the web are referring to Python 3 which is the
actively-developed version, recommended for new users.

Important note!: The "/2/" in the URL means those docs are for Python 2.x
When using Python 3, ensure that the docs you're consulting have a "/3/" in
them instead.

You're using Python 3, and the urllib2 module no longer exists in Python 3.
The URL/HTTP modules got refactored on Python 3. You want the
`urllib.request` module instead.

Although most folks nowadays use http://docs.python-requests.org/ instead,
though it's third-party and outside the std lib.

	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.

So, maybe Import doesn't mean import -- perhaps you expect import to 
retrieve content from the web and make it importable(1). That's not what 
python's import does. Python's version looks for a local module to import.

I'd suggest starting with the tutorial.

To an experienced user yes, to an inexperienced OP who can't even run a 
Python program without help a very emphatic no.
