Python and R are two popular programming languages for data science, each with unique features, but Python is preferred for its simplicity and versatility. Python's extensive libraries, like scikit, numpy, and pandas, enhance its data analysis capabilities. Major companies such as NASA, Netflix, and Google utilize Python in their products and services.

3. Python and R are among the most popular programming
languages for Data Science and are often found opposite to
each other in the room of debate on the fact that which one is
more valuable. However, both the languages have their
specialized features which makes them unique.
But what is making Python very popular?
One of the main reasons is its syntax simplicity and
operability on different environments making it easy for
programmers to write maintainable, large scale robust code
while in R, programming environment is so complex that it
requires a special training.
Libraries: Python provides data scientists with a set of
powerful and efficient libraries like Scikit, Numpy, Pandas,
Scipy that assist data analysis and statistical computing.
