I installed Python 3.6.1. And then installed pybrain using git (See Screen Shot). Then when I useimport pybrainit works but afterwards when I usefrom pybrain.tools.shortcuts import buildNetworkit gives me error that: Python 3.6.1 (v3.6.1:69c0db5, Mar 21 2017, 17:54:52) [MSC v.1900 32 bit (Intel)] on win32

Why is it doing like this? Kindly help me out here. Thanks
EDIT: Excluded screen shots. Added everything in post as per request.
except ImportError, e is Python 2 syntax and you've tried to run the code with Python 3. Install the latest version — the code seems to be fixed in git (it's except ImportError as e now, so it's suitable for both Python 2.7 and Python 3).
Just an update: I was able to resolve the issue by un-installing python, then installing python 3.6.2 (64 bit), using pip3 (pip3 install pybrain) I was able to install the latest version of pybrain which worked flawlessly. Thanks to everyone who tried to help me out when I was fairly new to python. Love this community!!

I am having trouble importing a library called pymssql.
I have read previous solutions regarding this issue on stack overflow. The following are the solutions that did not work:
Error importing pymssql
import pymssql Unicode DecodeError in windows 7
I am running a conda virtual environment with Python 3.7.9. The following is the output when I run python in the terminal.

So, this confirmed that I was using the correct Python version. Next, I tried to import a library called pymssql.
This looked like:
>>> import pymssql
This returned an error:

I have tried conda install pymssql and pip install pymssql. Neither of these solved the issue.
Any new solution for this. I am unable to from ciscoconfparse import CiscoConfParse
I tried several versions of ciscoconfparse in python3 usin gpowershell in windows10.

I still have not found a version that will let me import the module.
I browsed through several links here..but did not find an answer. The closest issue to mine is:
ciscoconfparse in Python 3.4 module doesn't import correctly
but not answer.
Any new info?
Thanks
I have reproduced the bug where Win10 and Python 3.7.0 cause problems.
FWIW, if you completely uninstall Python 3.7.0 (including manually deleting your Windows installation directory tree), then install Python 3.7.1, you should not have this problem with Windows 10.
I just installed Python to start experimenting a bit with Scrapy.
Found a tutorial to first install Miniconda and with this I was able to install Scrapy. Now the problem is that the software I'm trying to run also requires Twisted. So I installed twisted with pip.
Twisted seems to have been installed correctly but I'm still getting an error when running the script that the Twisted module could not be found.

Anybody a suggestion?
Thanks in advance,
You installed twisted for python2. When you use the command pip , you are installing a package for python2. You are using python3 (3.6.3). To install twisted for python3, you have to do:
pip3 install twisted
I hope this helps.
To try if twisted correctly installed, start python interpreter and type
import twisted
If you can't import twisted, you should check if it is in your python path.
Python path can be checked in the python interpreter as
import sys
print sys.path
The directory, where your twisted is installed has to be among those folders.
I am trying to make exe using py2exe in Python. When I import py2exe I am getting error like this:

Can any body help me fixing this out. I am not getting machinery module any where.
I just ran into this myself. I had installed 0.9 from pypi as well. If you look at the pypi page here py2exe on pypi, you'll see that the download only supports Python 3.3 and later and you should use the 0.6 download from here. I deleted the 0.9 egg after installing 0.6 and it worked after that.
I had same issue, because i had version py2exe0.9 and it is not supported for python2.7.
I downloaded lower version from here http://sourceforge.net/projects/py2exe/files/py2exe/0.6.9/py2exe-0.6.9.win32-py2.7.exe/download
and it works.
I am relatively new with Python. Here is my problem:
My environment was python2.6 with MacOs 10.6.8. I recently had to update my system with Python2.7 and some other stuff (Eclipse 3.6 and GoogleAppEngine). Python works fine within Eclipse, however, I want to keep the shell-mode in being able to quickly test small stuff on the commandline. I am getting this error message, and I need this to get rid of asap:

Anyway, this was the python version that my macbook was shipped with at buying time. I don't think i want to waste time on removing, re-stalling etc. an apple-approved python version. Does anybody know how I can get my system back to run properly? And why does this error occur at all? Thanks for quick help!
Try to run your new python within a virtualenv, so that it is isolated from the system install.
