I'm new to Python and trying to run a already written code. Can someone please explain the error below? And if possible, how do I resolve this?

This particular module incorporates FORTRAN subroutines. My guess is that whoever compiled your scipy binary did it in such a way that the FORTRAN standard library was being linked in as a DLL instead of statically. This DLL is not present on your system. Windows is trying to find it, but failing.

How did you install scipy? If you used a prebuilt binary installer, can you please link to the exact one that you used?

Try using depends.exe to find out what DLL it is looking for. http://www.dependencywalker.com/

The file that you want to check in depends.exe: c:Python27libsite-packagesscipyspecial_ufuncs.pyd

You're missing the dll that provides some function that you're trying to use.

Python: Running code from source that includes extension modules

I have started looking into distutils because I need to write an extension module in C (for performance reasons) and distutils seems to be the most straight-forward way.

I have had success building a C file into a Python extension module using "python setup.py build" but I am wondering what the recommended way for using that module during development is. While writing Python code I am used to just run the code from the source directory. But the built extension modules .so of course does not just end up on sys.path magically.

So how do I run my code so it will find the built extension module? Do I pass the output directory on the command line manually or is there some other solution? I would like to still be able to run the code from the source directory as I am using PyCharm to edit and debug the code.

Updating a filename's counter value failed each time in python

After a user selects a file from the form, that selection of his can be found form reading the variable 'filename'

If the filename already exists in to the database i want to update its counter and that is what i'm trying to accomplish by:

if form.getvalue('filename'):
 cur.execute('''UPDATE files SET hits = hits + 1, host = %s, lastvisit = %s WHERE url = %s''', (host, lastvisit, filename) )

For some reason this never return any data, because for troubleshooting i have tried:

data = cur.fetchone()

if data:
 print("something been returned out of this"_

Since for sure the filename the user selected is represented by a record inside 'files' table why its corresponding counter never seems to get updated?

using 3rd party dll in python

I would like to use the Gen3.dll functions from python. I understand that I can use ctypes to load the dll. I have been able to load the dll but cannot make any sense of how to use it once I have it loaded. I have been trying to understand the ctypes tutorial but I just can't wrap my head around it. I have attached a zip file of everything I have about the dll, including the Gen3.dll. Can someone point me in the right direction. My hopes are that I can automate the functions to provide a test program. The Gen3.dll communicates to a piece of hardware over a USB cable. Its mainly for setting voltages and loads and reading results.

Unable to import NHunspell.dll using ctypes in Python

Im required to import ha certain dll called 'NHunspell.dll' which is used for Spell Checking purposes. I am using Python for the software. Although I checked out several websites to properly use ctypes, I have been unable to load the dll properly.

When I use this code.

 from ctypes import *
 hunspell = cdll.LoadLibrary['Hunspellx64.dll']

I get an error

 hunspell = cdll.LoadLibrary['Hunspellx64.dll']
 TypeError: 'instancemethod' object has no attribute '__getitem__'

I guess it might a problem with the structure of the dll. But I have no idea how to import the dll properly.
