The ecosystem is a much bigger deal. There's an officially supported python library for every SaaS product on the market, and many libraries that are best-in-class in areas like data science. It takes minutes to write to pdfs, make graphical charts, edit images, and a million other nuancy, minor parts of apps that you want, but don't want to spend a ton of time writing.
Java is the only static language that features roughly equivalent levels of support ecosystem wide.
"and vice versa" < Sorry, but no. There's no equivalency here.
The only reason I would ever use python is for small scripts that I only run on my machine and don't need to deploy anywhere.
Maybe 10 years ago Python was an attractive language because Java sucked and C# only runs on windows and there weren't many other good choices.
Now there are many expressive languages that are also statically typed and fast. D, Swift, Kotlin, etc.
