[issue12671] urlopen returning empty string
New submission from Matthew Barnett pyt...@mrabarnett.plus.com:
Someone over at StackOverflow had a problem with urlopen in Python 3.2.1:
http://stackoverflow.com/questions/6892573/problem-with-urlopen/6892843#6892843
This is the code:
from urllib.request import urlopen
f =
urlopen('http://online.wsj.com/mdc/public/page/2_3020-tips.html?mod=topnav_2_3000')
page = f.read()
f.close()
With Python 3.1 and Python 3.2 it works OK, but with Python 3.2.1 the
read returns an empty string.

Returning a string
How is possible that I can print a variable, but when I use *return var* it returns an empty string http://paste.pocoo.org/show/97588/ -- http://mail.python.org/mailman/listinfo/python-list

2009/1/3 Kless jonas@googlemail.com: How is possible that I can print a variable, but when I use *return var* it returns an empty string What makes you think it's returning an empty string? You aren't doing anything with the return value in line 26 of your example. -- Cheers, Simon B. -- http://mail.python.org/mailman/listinfo/python-list

Simply because there is no code testing for that. And of course you don't show any debugging output, which doesn't help either. Diez -- http://mail.python.org/mailman/listinfo/python-list

That's the output got from ipython. As you can see, it prints 'Afghanistan' but it can not returns it. In change, the another strings are returned. Could it be because it isn't returning the value from the recursivecall? -- http://mail.python.org/mailman/listinfo/python-list

Diez Afghanistan AF Out[19]: u'AF' AFG Out[19]: u'AFG' 004 Out[19]: u'004' What is that? IPython? And I don't see no empty string here. *What* I see is the way python's interactive prompt puts out strings, like this: unicode(foo) u'foo' Do you mean by any chance that you don't understand why print prints foo, but the prompt shows ufoo? That is because the prompt invokes repr(o) to print out an object: print repr(unicode(foo)) u'foo' Which means that the output includes quotes and the u-prefix in case of an unicode object to help the user to see what the current object looks like.
