#31385 — Python on Windows

Downloaded and installed Python 2.7.3 for windows (an XP machine).

Entered the Python interactive interpreter/command line and typed the 
following:

	>>>import feedparser

and I get the error message "No module named feedparser".

There is a feedparser.py file lurking around - so I suppose Python 
cannot find it.

Anyone: What to do?

Hi,

feedparser.py is not a Python standard library. So, if it feedparser is located in a non-standard folder you have at least the following two options:
1. Update the PYTHONPATH environment variable such that it includes the path the installation location of feedparser.py

2. Add the path to feedparser.py directly in the script that uses it. Something like the following:
import sys
sys.path.append("path to feedparser.py")

import feedparser

Regards,

Marco

Did you install it into the site-packages directory? Or did you cd to
the directory it's in, and launch, or place it into the directory
you're trying to launch it from?

I'm guessing your python path is not set up.  Look here:

or google windows xp setting python path

Thanks to everyone who replied.

Python was installed in the subdirectory C:\Python27 with the file 
feedparser.py residing in C:\Python27\Lib\email.

Setting the Windows environment variable (which did not previously 
exist) to C:\Python27\Lib\email allowed me to import feedparser 
successfully.

However, it seems that this feedparser module is not the module I wanted.

I'm trying to follow an introductory Python course from the magazine 
Linux Format (issue number 120 I think). The article includes the 
following lines:

>>> import feedparser
>>> url = “http://weather.yahooapis.com/forecastrss?p=UKXX0637&u=c”
>>> data = feedparser.parse(url)

This is fine using Ubuntu (after installing the feedparser package) but 
now, running XP I get

>>> data = feedparser.parse(url)
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'parse'



So there seems to be at least 2 feedparser modules - the one I have does 
not include "parse". How can I identify the correct one? How do I

This is all confusing and frustrating.

Some searching suggests I need the 'universal feed parser' code. I can 
find documentation for this but no code/module file. Is it available 
only for Unix-like OS's?

I'm very surprised that the article tells you to import a non-standard
module without telling you where to download it. I imagine that the
module is this one:

  http://pypi.python.org/pypi/feedparser/

(In general, PyPI is the first place to look for Python packages).

> This is all confusing and frustrating.

Understandably. It's not unknown, but it is unusual for two
identically-named packages to exist for Python. It's more
unfortunate when it's one used in a beginner's article.

If you understand how to download the .zip file from the page above and
unzip it then you need to go to the directory where the unzipped files
are and run:

  python setup.py install

If you're not sure how to do any of that, feel free to post back here or
to the python-tutor list [1] which is a little more experience in
helping newcomers.

Just try taking your ubuntu's /usr/share/pyshare/feedparser.py onto
your windows box??

As an aside, this is not the best use of the PYTHONPATH
variable. (I would argue that, on Windows at least, there's very little
need for the env var).

In general, you'll want to be using a mechanism such as pip:

  http://pypi.python.org/pypi/pip

which will look things up on PyPI so you can just do "pip install
newmodule". This will install into c:\python27\lib\site-packages. The
same for a module you install "manually" (ie python setup.py install) or
via an .exe or an .msi from PyPI or elsewhere.

There are other possibilities: .pth files, the PYTHONPATH env var,
virtualenv, user-install directories which you can read about, but in
general, just let the standard mechanisms install into
c:\python27\lib\site-packages (which is automatically on sys.path) and
go from there.

Once again thanks to those that replied.

Since I posted, I found a version 4.1 on sourceforge.

I guessed/muddled my way through installation and it seems to work.

To Tom Golden,
   Thanks for the link to http://pypi.python.org/pypi/feedparser/ - I 
couldn't find it and I don't know how you did.

The version at http://pypi.python.org/pypi/feedparser/ is 5.1. Can I 
simply install 'over the top' of the previous one or do I need to 
uninstall V4.1?

At least from where I'm standing, it's the second Google result for
"python feedparser" but in fact I Googled for "PyPI feedparser" because
I knew that that was the most likely bet.

You should just be able to over-install. No harm in deleting the
previous one, but you probably don't need to.

For the benefit of the OP and others this is worth reading on how to get 
Python packages from pypi that let you get Python packages from pypi 
http://stackoverflow.com/questions/4750806/how-to-install-pip-on-windows :)

Heh. I avoided trying to explain how to install pip because the OP
seemed unfamiliar with enough concepts already. It never occurred to me
to use easy_install to install pip!

And if you have a pip.bat from some Perl installation sitting before 
python's Scripts dir in your %PATH, remember to use 
"pip.exe install newmodule" instead.

My Strawberry Perl has this "Perl Installation Package". Maybe I should
rearrange my %PATH?
