python vs julia
Julia is a very mature and stable programming language, so if you're looking for something new and exciting it might not be the best choice. Python on the other hand has become one of the most popular languages in data science due to its ease-of-use and versatility. The syntax is more similar to python than Julia's lispy nature would suggest.

That being said I think both are great choices with different strengths that fit into various niches within Data Science.
