I recently started writing a simple client using the Blogger API to do some basic posting I implemented the client in Python and used the example code verbatim from the Blogger Developer's Guide to login, get the blog id, and make a new post. I ran the script and everything went fine until I got to this line:
return blogger_service.Post(entry, '/feeds/%s/posts/default' % blog_id)
I got the error message:

By which I'm taking it that ElementTree is at fault here. I installed ElementTree via
sudo python setup.py install
in case it matters. Is there some known incompatibility between ElementTree and Python v2.7.1? Has this happened to anybody else and how did you get it working? If you need any additional information, please reply to the thread. All the source code that is relevant is basically just the example code from the Developers Guide mentioned above. I haven't modified that at all (not even the variable names). Any input is greatly appreciated.
The stacktrace is actually pretty clear about this: You're calling decode() on a list instead of a tree element. Try getting the first element from the list and calling decode() on that:
firsttext = self.text[0].decode(MEMBER_STRING_ENCODING)

I'm trying to parse some Java code in Python using ANTLRv4. I've tried to follow this post, but I get the following error:

I can't figure out what I'm doing wrong. The file I'm trying to parse is proper Java, it's extracted from the docker-maven-plugin package. I've tried with other files, but I get the same error.
Any idea ?
Actually it was just a problem of violent refactorization... I've changed line to line_number in my code, and it actually changed it in librairies too. Changing it back to line cleared the problem.
Thanks to #Thomas Kläger for making me realize it.
I've been migrating some Python 2.7.11 code to 3.5.1 after running into trouble with unicode. This was the last straw - since I started using the venv module there's no reason to be on 2.7 just because someone doesn't like 3!
The problem occurs while trying to run a one-way sync (ie. downloading changes only).
Here is the full error message, paths shortened:

dropbox.rest.ErrorResponse: [400] 'Invalid "cursor" parameter: u"b\'\'"'
Searching for "invalid cursor parameter" wasn't any help, so I thought I'd come here.
u"b\'\'" is the key here. I just couldn't understand how that representation had ended up being sent as a string.
The issue was in reading the old cursor from a file (which for this example is empty): in Python 2 I had opened the file in mode rb - in Python 3 just r is all that's required, and everything works.
Hurrah!
I'm trying to build a python function with web.py and SQLite that will allow users to search for a given string within a description field and will return all matching results.
Right now I've gotten to the below function, which works but only if the input is an exact match.
def getItem(params, max_display):
query_string = 'SELECT * FROM items WHERE 1=1'
description = params['description']
if params['description']:
query_string = query_string + ' AND description LIKE $description'
result = query(query_string, {
'description': params['description']
I've tried to implement this feature with LIKE "%$description%"' , however I keep getting the below web.py error.

Any thoughts on what might be going wrong with this function?
Thanks in advance!
What do you think is going on with parser.py?
Here is the relevant portion of the error message:
File
"/Users/sokeefe/homebrew/Cellar/python/2.7.10_2/Frameworks/Python.framework/Versions/2.7/lib/python2.7/compiler/transformer.py",

return self.transform(parser.suite(text)) AttributeError: 'module' object has no attribute 'suite'
So, somewhere there is a file called parser.py, which defines a function called suite(), which is used by some library code that executes when your program executes. But because you named one of your files parser.py, when the library code executes, python searches for a file named parser.py, and python found your file first, and there was no function named suite() in your file.
I have the following code in Python 3.3:
ftpHost="myhost"
link=ftplib.FTP(ftpHost)
link.login(user="me",passwd="alsome")
t=link.nlst()
link.quit()
print(t)
The output I get is
['.','..','dir1','dir2']
In the Python 3 document, it is written that FTP.nlst has been "deprecated since version 3.3: use mlsd() instead". When I tried
ftpHost="myhost"
link=ftplib.FTP(ftpHost)
link.login(user="me",passwd="alsome")
t=link.mlsd()
link.quit()
print(t)
The output I get is
<generator object mlsd at 0x0000000002A0F120>
which is not the desired answer. I can't figure out where within t can I get the directory listing. How can I use mlsd to get the directory listing?
If I try #fourtheye 's suggestion and change to
t=list(link.mlsd)
the error I get is

ftplib.error_perm: 500 MLSD not understood
Generators dont keep entire results in the memory. The results will be generated when asked for one, with next function. In order to get the values as a list, use the list function with link.mlsd(), which will internally call next on the generator object.
Just change
t=link.mlsd()
to
t=list(link.mlsd())
Who runs the FTP host? The 500 MLSD not understood means they don't support the MLSD command. That's a later extension to the FTP command set, so they're just out of date. The specification is here:
https://www.rfc-editor.org/rfc/rfc3659
Unless and until they upgrade to a "modern" version of FTP, just continue to use nlst().

Anyone can help me?
It seems to be a bug in Google API Python library. I checked gdata-2.0.16 and noticed that DeleteResource() function uses only URL of the resource (gdata/docs/client.py lines 540-543), but later checks for hasattr(entry_or_uri, 'etag') (gdata/client.py lines 737-741) and of course string value (uri) doesn't have etag attribute.
You may work around it using force keyword argument:
import gdata.docs.data
import gdata.docs.client
client = gdata.docs.client.DocsClient()
client.ClientLogin('xxxxxx#gmail.com', 'xxxxxx', 'XxX')
for doc in client.GetAllResources():
if doc.title.text == 'qpqpqpqpqpqp':
client.DeleteResource(doc, force=True)
break
If you want you may report an error to library maintainers (if it isn't already reported).
This issue has been fixed in this revision:
http://code.google.com/p/gdata-python-client/source/detail?r=f98fff494fb89fca12deede00c3567dd589e5f97
If you sync you client to the repository, you should be able to delete a resource without having to specify 'force=True'.
