There are many large programs build in python… and Data Science is built around Python… So…. I would say it has a strong chance?

Google was even built on python!

As programming language? No crystal ball here, but I have seen a lot of programming languages come and go. Some remain bit longer but no one can estimate the future. Look at normal applications: not always the best applications live longer, it depends on much more than just the quality. I have know presentation applications, spreadsheet applications that were way better than MS equivalents, but they were killed by MS.
