i am running python 3.2.6 on an a2hosting shared server. when i do
import cgi
i get:
Traceback (most recent call last):

EOFError: EOF read where not expected
how can i solve this? i do not have root access.
edit:
this is the answer i got from a2hosting support:
Hello, Unfortunately, we really cannot provide development assistance here. This is quite above and beyond our scope of support. While we'd like to be able to provide support for each and every program, language, script, etc, that comes out, it's just physically impossible to do so. You'll want to work with your development team, or the applications developers to ensure that this is something that's investigated thoroughly.
i circumvented the issue by installing a different version of python, following this: https://www.a2hosting.com/kb/developer-corner/python/using-a-newer-version-of-python

I try to import discord in python 3.5, but I get the following traceback:

from wsgiref.handlers import format_date_time
ImportError: cannot import name 'format_date_time'
I installed discord inside Python35-32\Scripts using pip install discord. Additionally, I installed asyncio using pip install asyncio in the same directory.
The error pops up in my command prompt, when I type in "python", wait for it to open, and then type "import discord". I'm saying that just to be clear that it's not a "I have a file named XXX.py which clashes with something from the discord library" type of error.
Based on the comments you have added and the line
File "C:\Python\Python35-32\lib\site- packages\aiohttp\protocol.py", line 11, in <module>
from wsgiref.handlers import format_date_time
ImportError: cannot import name 'format_date_time'
The problem seems to be that 'format_date_time' could not be imported from the built in library wsgiref. Turns out that the file ...\Python35-32\lib\wsgiref\handlers.py was completely empty indicating that something corrupted your python installation.
Two possible solutions:
Reinstall your python completely which also has the benefit of solving other potential corruptions that you might not have noticed yet (Note that the underlying cause for this corruption remains unknown)
Go into the Cython git and copy the contents of the handlers.py into the local file. This is a very specific solution however and you should be aware that other parts of your python installation might also be corrupt.
Maybe you wanted to pip install discord.py instead of discord?
I have a cloud instance of a Linux machine (openSuSE) with multiple users.
I have created a virtual environment and installed all my required libraries (including Klein).
I have two users "a" and "b".
While logged in as "a" and inside virtualenv, when I open python shell at home directory and type
import klein
it imports normally.
Now when I change directory to
/home/b/
and run the same (open python shell, import klein) while being in the same virtualenv, it gives me an error.

#attr.s
AttributeError: module 'attr' has no attribute 's'
Command "which python" gives same address at both location which is my virtualenv python address and that should be expected.
But what causes this weird python shell behavior.
Thank you
I solved it and a very shameful reason caused the error.
One of the modules Twisted uses is "attr" module. I had named one of my files attr.py and that is what was causing all the error.
I myself am not deleting this question if moderation has no problem, maybe somebody like me might be stuck at the same situation. It may help them.
Never name your python files same as that of any standard module unless overriding.
Also if your issue persists, then Jean's answer will definitely resolve it.
There can be multiple different Python packages that provide the same Python module. For example, there are at least two packages that provide the attr module:
https://pypi.org/project/attr/
https://pypi.org/project/attrs/
It's possible you've installed the wrong package based on the requirements. You can check what you have installed with pip freeze.
I have successfully installed cherrypy but when I try to import it, I get following error. I am a newbie and have spent quite a bit of time trying to get this to work, so any help would be highly appreciated.

From what I can see, it's a bug with that version of CherryPy. You'd be best upgrading to a more recent version instead.

ImportError: cannot import name CRegExp
Ipython worked just fine a week ago and now I get this error. Can anybody suggest what might be causing this?
As #favoretti mentioned, this is an import issue in utils.traitlets.
I would recommend upgrading to EPD 7.3 and see if that fixes the issue. I feel bad suggesting a "brush it under the carpet" solution but if you're just starting out with python delving into the bowels of IPython might be a bit of a headache.

I am getting above error. I have followed steps given on the official site of ZeroMQ.
Had a similar issue when building for Java, UnsatisifedLinkError, after the so libraries were copied to /usr/local/lib, seems like your issue might be the same...I fixed it by logging off then logging back in again, I read something about the libraries not being visible until the user logs back in, weird, but it worked for me.
