I haven’t run into anything where Python either couldn’t be used or shouldn’t be used, except for the browser of course.

I think software engineers with any significant amount of experience recognize you can build an application that does X in just about any language. To me, the largest difference, the greatest factor in which language to choose, is the existing packages. Simple example- there are several packages in Python for extracting text from PDFs (using tesseract or not). C# has maybe one tesseract wrapper? I recall working with PDFs in .NET being a nightmare. I think we had to buy a license to some software because there wasn’t a free offering. Python has several.

This is VERY important because we as software engineers, even if we wanted to reinvent the wheel sometimes, have very limited time. It takes an obscene number of man hours to develop a SalesForce or a Facebook or even something smaller like a Linux distro.
