• Another advantage of using Python is the availability of a community of developers using the same programming language. Python being the most popular programming language, the number of people working on it is high.

Data Science is a vast field which requires working with a large number of libraries. Finding the right programming language to master is, therefore, important for efficient working with all the libraries-

R programming: The only challenge of R is its steep learning curve, but it is an important language for various reasons

• It has a huge open-source community that provides numerous high quality open-source packages for R.
• It boasts of smooth handling of matrix operations and has large statistical functions.
• It has ggplot2 that enables data visualization

Python: With lesser packages than R, Python is still considered to be popular with data scientists. The reasons for that is-

• Libraries like pandas, scikit-learn and tensorflow equip Python to provide most library needs for data science purposes.
• It is very easy to use and operate.
• It has an open-source community that is considered one of the largest one.

SQL: Working on relational databases, Structured Query Language has-

• Readable syntax
• Efficiency in updating, manipulating and querying data for relational databases.

Java: One of the oldest programming languages, Java has limited libraries limiting its potential. Nevertheless it has some advantages.

• Systems coded with Java at the backend makes it easier to integrate data science projects with it making it a compatible option.
• It is a high performance, general purpose, compiled language.

Scala: Working on JVM, it is considered rather complicated. But it does have some advantages:

• Running on JVM, Scala can run on Java as well.
• Used alongside Apache Spark it enables high performance computing cluster.

The following are the steps to downloading Python 3 for Windows:

Download and setup: Go to the download page and setup your python on your windows via GUI installer. While installing, select the checkbox at the bottom asking you to add Python 3.x to PATH, which is your classpath and will allow you to use python’s functionalities from terminal.

Alternatively, you can also install python via Anaconda as well. Check if python is installed by running the following command, you will be shown the version installed:

python --version

• Update and install setuptools and pip: Use below command to install and update 2 of most crucial libraries (3rd party):

python -m pip install -U pip

Note: You can install virtualenv to create isolated python environments and pipenv, which is a python dependency manager.

You can simply install python 3 from their official website through a .dmg package, but we recommend using Homebrew to install python as well as its dependencies. To install python 3 on Mac OS X, just follow the below steps:

• Install xcode: To install brew, you need Apple’s Xcode package, so start with the following command and follow through it: $ xcode-select --install
• Install brew: Install Homebrew, a package manager for Apple, using the following command: 

/usr/bin/ruby -e "$(curl -fsS https://raw.githubusercontent.com/Homebrew/install/master/install)" Confirm if it is installed by typing: brew doctor

• Install python 3: To install the latest version of python, use: 

 brew install python

• To confirm its version, use: python --version

You should also install virtualenv, which will help you create isolated places to run different projects and may run even on different python versions.
