Answer 2

What do you mean by "name them by numbers"? Can you explain please?
If you click "Discover New Courses" you find a selection of programming languages popular in data science. Don't know how common Julia is...
Martin Taylor on 1.
I begin to wonder when the courses "Python for Cooking", "Python for Singles" and "Python for Java" will finally be released :)

Answer 3

Maybe R and Python

Answer 4

OT (sorry):
Simon Sauter now I will always get suspicious when someone tells me their girlfriend's name is Ruby or Julia...

Answer 5

Lisa aren't all programming courses implicitly for singles? ;)

Answer 6

Python and java

Answer 7

Python and R is a short answer.
I liked R more than Python but you could learn both, specially Python since is way more popular and has more uses apart of data science, so is a better option to learn in the overall scheme of things.
