How to run Excel Solver function from Python

I am trying to write a Python script file which analyses data in an
iterative manner. During each iteration, I wish to utilise the Solver
function in Excel to perform some constrained, non-linear fitting to
the data. I have a VBA macro which runs the Solver, and am using
self.xlapp = win32com.client .dynamic.Dispat ch("Excel.Appli cation")
..
..
..
self.xlapp.run( macro)

I am using the Python script to interface with another software called
ABAQUS and am executing the script through the ABAQUS Python
interpreter (which is Python 2.0). Howvever, when I run the script I
get the error

'Solver : An unexpected internal error has occurred, or available
memory was exhausted'

Could anyone please provide some explanation to this problem? The
macro and Solver run fine if I don't call from the Python script.
Thank you and any help is much appreciated.

Having widened my search, I found that this problem seems to be
related to Excel itself and not many have found a solution. But I
found this and it works a treat!!

Sorry for posting this problem at the wrong place.

has anyone every used the solver add-in for Excel? it allows you to solve linear and non-linear problems given certain conditions. I was wondering if something like this exists already in .NET?

A co-worker and I want to increase our knowledge of Python. I have a tiny bit of exposure to python. He has none, but has wide experience with C, C++, NET, C#, etc. We agreed we'd do a Sudoku solver. I'd do the GUI, he would do the solver code. My question is this: I assume that once I invoke mauinloop, the loop just cycles between bound events...(if not true, please tell me)...so how do I "branch" out to the solver code, which will be in...

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
