For those of us who are Python users, I would like to highlight a new tool called PyQSPICE. It works with QSPICE’s command-line interface to load QSPICE simulation results into memory for plotting in Python.
This is an open-source project hosted on GitHub. It is not supported by the QSPICE team.
Hi Jeff.
For me this is very interesting information. Maybe I can get EAGLE to show an output window for QSpice instead of a PCB.
Thank you very much. Tom
Hi Jeff
My colleague told me that there is another 
“PyQSPICE”.
GitHub - nunobrum/PyQSPICE: Python Library to operate with QSpice and read simulation output files
The author is the same person who wrote “PyLTspice”.
Is this the same one you mentioned?
They are two different projects. There’s more discussion on the one I mentioned here:
I’m glad there is enough interest in the concept to drive two different developments!
Hi,
I’ve got an offline DM Q&A regarding this Python module and here’s summary which may help someone who gets the same questions.
Q:: Any good documentation?
A:: Sorry…not yet.
Q:: How to tweak a parameter, run a sim and repeat/loop?
A:: This example is running 2 sims from one next list by changing the netlist “.cir” file with Python regular expression “re” module.
Q:: Why “SJIS” encoding, in the Python module?
A:: See this discussion. The QSPICE uses “Latin-1 Supplement” and many file-encoding judgement routines (checked a couple of standalone encoding detection programs) think it “Shift JIS”, with a probability view point. Just to avoid Python error message, I use the “SJIS” encoding and I know I’m dealing with a file of “Latin-1 Supplement”.

PyQSPICE is very good and I have used it already.
How do I print the dc operating points if I am using PyQSPICE?? I do not see that function in the PyQSPICE class and was hoping if you could please help with that? It will be a good starting point to see dc operating points of all nodes (and currents)
before the PSRR circuit is simulated (or any other AC sim is triggered)
I run a quick trial and I see PyQSPICE can support your “.OP” needs.
I’m on the road and please wait for me next week 
I’ll delete this post when I update PyQSPICE for the “.OP”, by replacing my post with the detail how to handle “.OP” on PyQSPICE.
I believe I made an over commitment, it’s the Thanks-Giving week here in USA…Within Nov, I’ll try to get it updated for “.OP”.
thank you masashi! I look forward to your uprate on how to use .op within PyQSPICE and getting a text file with outputs printed for the operating point (just like what one can see in the terminal).
Please check updated ver.2023.11.29 PyQSPICE.
