If you can use third party library, I think you can use Aho-Corasick algorithm.

Re: Python replace multiple strings (m*n) combination
Another possibility is to form a suffix array
(https://en.wikipedia.org/wiki/Suffix_array#Applications) as an index for the
string, and then search for patterns within the suffix array. The basic idea
is that you index the string you're searching over once, and then look for
patterns within it.
The main problem with this method is how you're doing the replacements. If
your replacement text can create a new string that matches a different regex
that occurs later on, then you really should use what INADA Naoki suggested.

Oh, I'm an old hand at finding Microsoft GUIDs. As a tester at Microsoft, when a nightly build's uninstall failed (which was often because the setup team was so crappy), we had to find and delete every blasted registry key and installed file for the application. I had 50+ servers in my lab, so I identified all the keys and files on one server and sent the delete operations out over the network to the others. This method was laborious, but a fraction of the work needed to wipe and fresh install 50+ servers. > Might have to export the entire registry first, > install, export entire registry, and run a differences of the two > > >I like the idea of pulling the wire (cutting internet access) when I > >use it.

If you want to turn internet access on and off more easily in Windows 7, go to Control Panel\ Network and Sharing Center and in the left hand menu click on Change Adapter Settings. Create a shortcut to Local Area Connect and put it on your desktop. Local Area Connect has the internet enable and disable button. I also use Networx to keep track of who is phoning home. -- https://mail.python.org/mailman/listinfo/python-list

Oh, "pulling the wire" and seeing who's trying to call home is quick and easy enough, in a number of different ways. I don't have Win7 nor want it, but as this thread evolves, perhaps someone else reading this will find your information useful. -- https://mail.python.org/mailman/listinfo/python-list

Thanks Mark, I will take a look at it. It sounds like a real pain to keep on top of all the invasions from Microsoft and who knows else, but likely that's all set up in Visual Studio Community's .NET installation code. I don't/won't have any .NET after about version 3 on my computers, so it just occurs that I may not even be able/willing to install it. Later versions of dotNet not only phone home, but can also serve as a backdoor to the NSA and other government nasties. That's one reason why they're all so keen on killing XP, because anything before SP3 can't be instrumented in that way, and a major reason why I'm sticking with XP SP2 until I can get back on Linux. And on top of that, now you say Visual Studio Community Edition takes a long time to download and install, even if you're willing to live with all that comes with it (I'm not). I almost have a verifiably working version in Python of the funcionality I want from that C library, so I may just bag Visual Studio. It would be nice to see what calculations they're exactly doing in that C library because the authors are authorities in this area, but the body of calculations is all written up in other sources. Once I have a Python version I can verify against another dataset I have and it checks with the written sources, I may not care whether I have that C library to compare to or not. But if I really want to see all the execution steps in the C code, going with Visual Studio Code is probably the way to go. Heck, I thought it would be a shortcut to download the open source C code and model my code after it, but it's turned into a rats nest of trouble, which likely won't tell me anything I don't already know at this point.
