NEWB problem with urllib2

I just installed PyDev into Eclipse using the 'update' method and did
the standard installation. I allowed it to Auto Configure itself and
ran a "Hello World" module to make sure I was in the ballpark.

I got an starting module up and have run "Hello World" but now am
stuck on getting urlopen to import from urllib2 for the following
example.

from urllib2 import * # doesn't give me an error
ur = urlopen("http://www.daniweb.com/forums/thread161312.html") #
gives me Undefined Variable: urlopen

so I tried just

import urllib2 # Eclipse gives "Unresolved Import"

Is urllib2 not on my path? Isn't urllib2 in the standard installation
and shouldn't that automatically be on my path? If not, how can I get
it on the path?

ThankS!!

This sounds more like a PyDev and/or Eclipse problem than an urllib2 problem. :)

One thing you can check: open the "raw" python interpreter outside of
Eclipse and try importing urllib2 there. You might also try the
interpreter interface within Eclipse (if it provides one.)

Thanks Simon!

You are right.. I also believe it is something with Eclipse.

I've been working since... the module below runs.. but Eclipse is
still showing an error when I reference urlopen with a little red X...
saying it is an undefined variable in the IDE.. but not giving me an
runtime errors.

#URL LIBRARY
from urllib2 import *

def openfilereadaline(a):

f = open(a)
print f
for line in f:
print line.rstrip()
f.close()

def openWebSite(a):

ur = urlopen(a) #open url
contents = ur.readlines()#readlines from url file
fo = open("test.txt", "w")#open test.txt
for line in contents:
print "writing %s to a file" %(line,)
fo.write(line)#write lines from url file to text file
fo.close()#close text file

if __name__ == '__main__':

openWebSite("http://www.daniweb.com/forums/thread161312.html")

print "Hello World"
