Is R similar to Python?

Python and R are the preferred languages in Data Science, Data Analysis, Machine Learning, etc. Although they are used for similar purposes they differ from each other. R mainly focuses on the statistical part of a project while Python is flexible in its usage and data analysis tasks.

Which is better R or Python?

Speed and performance. Python is beginner-friendly, which can make it a faster language to learn than R. Depending on the problem you are looking to solve, R is better suited for data experimentation and exploration. Python is a better choice for large-scale applications and machine learning.
