I'm pretty new to Python and wanted to try it out by making some stuff happen with my Arduino microcontroller. So I downloaded the serial library, placed it into the Lib folder and imported it into my programm. Unfortunately the import causes the following Syntax Error:
Traceback (most recent call last):
File "C:\Python33\test.py", line 2, in <module>
import serial
File "C:\Python33\lib\serial\__init__.py", line 19, in <module>
from serial.serialwin32 import *
File "C:\Python33\lib\serial\serialwin32.py", line 12, in <module>
from serial import win32
File "C:\Python33\lib\serial\win32.py", line 196
MAXDWORD = 4294967295L # Variable c_uint
^
SyntaxError: invalid syntax
I am using Windows 7 64 Bit. How can I fix this? I don't find any other versions of the serial module.
Maybe 2to3 can help you here...
It may be that both python2.X and python3.X are on your PC. Please check whether the pyserial-2.X file exists in the python3 directory(Python3X\Lib\site-packages). If it does exist, please try to cut this file into the python2X directory and use the command
pip3 install pyserial

I'm trying to write Python code to manipulate Xerox FST files, and I've installed the Python bindings for libxfsm and the XFSM library available through http://fsmbook.com. I'm running 64-bit Ubuntu. The installation goes fine, but when I try to import the xfsm module, I get this error:
>>> import xfsm
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python2.7/dist-packages/xfsm/__init__.py", line
30, in <module>
import xfsm.errors # So error handler gets installed
File "/usr/local/lib/python2.7/dist-packages/xfsm/errors.py", line

from xfsm.utils import *
File "/usr/local/lib/python2.7/dist-packages/xfsm/utils.py", line

libc = cfsm.load_library("c")
File "/usr/local/lib/python2.7/dist-packages/xfsm/cfsm_api.py", line
366, in l oad_library
raise ImportError("%s not found." % libname)
ImportError: c not found.
Inspecting the source code for the Python interface, it looks like it is trying and failing to find libc, and failing, but I am at a loss on how to fix that.
Has anybody else gotten the Python-XFST interface working, or have any idea what's going wrong and how to fix it?
I had same problem on 64-bit Ubuntu 14.04. The problem is it can't find libc. In my case libc on my OS is name libc.so.6(I don't know why, I am new on Ubuntu). But the Python-XFST doesn't recognize it (Detail your can refer to source file)
My solution is simple, just modify xfsm/utils.py file in
**Line 39** : libc = cfsm.load_library("c")
to
**Line 39** : libc = cfsm.load_library("libc.so.6")
Remember to add the path to libc.so.6 in env.
Im trying to figured out this problem. Yesterday I installed PyScripter and since then, scripts doesnt work. When I run any script (in PyScripter or IDLE) and trying to "import arcpy", it gets this error:
import arcpy
Traceback (most recent call last):

from RuntimeError import RuntimeError
ImportError: No module named RuntimeError
Have somebody any suggestion how to fix it?
Thanks to all very much!
Sounds like the module is not installed properly (or at all). To verify, do the following:
open a shell and start the python shell by typing python
(If this doesn't display an error, check that python is added to your system path or if it is even installed at all. But if you've used Python on said machine maybe system path issue)
enter the commmand help('modules')
review the list of modules that's returned to see whether arcpy is included
if not, then you may have to reinstall the module
I was successfully using python in my programs and importing necessary modules including MySQL. However, to get IDLE on my computer I downloaded a new copy of python. I'm really not sure what I did or what happened but when I try to run a program now that uses MySQL I get the following error:
Traceback (most recent call last):
File "MyFile.py", line 11, in <module>

File "/Library/Python/2.7/site-packages/MySQL_python-1.2.4b4-py2.7-macosx-10.8-intel.egg/MySQLdb/__init__.py", line 19, in <module>

Expected in: flat namespace

any ideas on how to fix this?
Actually I fixed the problem by reinstalling MySQLdb following the step found here. I'm not sure how well this will work for additional modules though
I'm trying to configure and run SVN post-commit hook sending mails. I've downloaded class mailer.py, installed Python 2.7 and svn-win32 bindings for svn. The machine is Windows-7 64 bit, the Python is 32 bit. Now the mailer.py ends with error, which is caused by import problem.
When I in python console type "import svn.core" I have following error:
>>> import svn.core
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "c:\tools\Python27\lib\site-packages\svn\core.py", line 19, in <module>
from libsvn.core import *
File "c:\tools\Python27\lib\site-packages\libsvn\core.py", line 5, in <module>
import _core
ImportError: No module named _core
while in directory site-packages/libsvn are files such as: _core.dll
I've installed other bindings, pysvn, that was installed correctly, but as far as I've noticed, it's the totally other API so I can't use that for python.py
Does someone had similar problem and knows how to deal with it?
The Python bindings need to load the native Subversion libraries (DLL's). If your Python is 32-bit then you would need 32-bit versions of the native Subversion libraries on PATH.
I have problem like this. Trouble was that python just can not import this library (svn.core and other).
I just make:
import sys
sys.path.append("C:\csvn\lib\svn-python").
My file core.pyc was in C:\csvn\lib\svn-python\svn. Hope it helps somebody. Such behacior for me is strange because there is no "init.py" or "init.pyc" file in svn-python directory. But it works.
Getting the following error when trying to run SPSS from an external Python IDE.
import spss
yields the following error

Ran the Python essentials plug-in with no errors. Funny thing is that I dont get an error when I run this in a syntax
BEGIN PROGRAM PYTHON.
import spss
num = spss.GetVariableCount()
print num
END PROGRAM.
Any help will be much appreciated.

I believe I figured out the issue. I needed to configure Eclipse to see the external python modules that are created when you install the SPSS/Python plugin. I had to set a reference to the modules when configuring the project.
Once I did that, it looks like I am up and running!
