Which one is better to learn R language or Python ?

Answer 1

With the disclaimer that I only have much experience with the first and want to learn the latter... If you're going to be sticking to statistical analyses and simulation modeling (stochastic or equation-based), R is fantastic - I recommend it. If you work or are planning to work in the sciences, being familiar with R is an in-demand skill.

...but Python is fun and flexible and can still be/is great for stats and simulations, so if you have broader or different aims for your coding than what I mention above, you won't go wrong learning Python!

Simply, in agreement with the other poster:
- Depends what you want to do
- If you can find the time, why not learn both? :)

Answer 2

It depends on what you are trying to do.
