Why sas is considered over r and phyton??

[RW9]

Its not, SAS is a validated piece of software, accepted by autorities as such, plus there is a large user base.  R is open source software with lots of user made packages.  Python is a different programming language altogether.  When writing a question try to be specific, what do you want to do, what software best fist your scenario etc.  One thing is not better than another, only different.

Apples (R), mixed pickles (Python), and a full-grown grocery store (SAS). Not even apples and oranges here.

40+ years of development may have some impact...

Dedicated support, a strong user base, verified modules rather than packages from random people off the street, and it can handle big data without having to change your algorithms or processes (90% of the time).
