Arlington is home to the University of Texas, a major urban research university and hence employers in Arlington generally prefer data scientists to have mastery over some software and tools. They generally look for:

• Education: Getting a degree in Data Science, like a Master's degree or a Ph.D., will benefit you a lot in the long run. You can also try getting some certifications.
• Programming: Programming is one of the most important skills required to be a data scientist. You can try Python or R programming language. Before you move on to any data science libraries, you must learn Python basics.
• Machine Learning: Once you have collected the data and converted it into a structured form, you will need deep learning and machine learning skills to find relationships and analyze patterns.
• Projects: You must try exploring old projects and creating new ones to build your portfolio. You need to try your hands on real-world projects to improve your skills and build your portfolio.

• Multi-paradigm programming language – Python is a programming language with various facets that makes it most suited for the Data Science field. It is an object-oriented, structured programming language that comes with several packages and libraries that can be beneficial in the field of Data Science.
• Simple and readable – It is one of the most commonly preferred languages used by Data Scientists because of its simplicity and readability. There are a vast number of dedicated packages and analytical libraries that are customized to be used in the field of Data Science. This makes it more attractive to Data Scientists as compared to any other programming language.
• Wide range of resources – Python is a programming language that comes along with a diverse range of resources. Whenever a data scientist is developing a program for Data Science model in Python and gets stuck, they have these resources available at their disposal.
• The Python community – The other benefit of using Python as a programming language in Data science is the vast community dedicated to the language. Currently, there are millions of developers who are working on the same programming language and the same problem every single day. So, as a developer, you will get plenty of help in resolving your problems because there is a huge possibility that someone has gone through the same issue and found its solution. Even if there is no solution available, the Python community will help never step back from helping a fellow Python developer.

Here are the 5 most popular programming languages used in the Data Science field:

• R: Even though the language has a steep learning curve, it offers the following advantages:
  • There are many high-quality open source packages provided by the big, open source community of the language. 
  • The language is capable of handling complex matrix equation while dealing with loads of statistical functions smoothly.
  • R can be used with ggplot2 to provide data visualization. 
• Python: It is one of the most commonly used programming languages in the field of data science even though it has fewer packages than R. It is because of the following advantages that it offers:
  • It very easy to learn, understand and implement.
  • It has the support of a big open-source community as well.
  • It has most of the libraries that you might need for data science like scikit-learn, tensorflow, and Pandas.
• SQL: Required for working with relational databases, SQL is a structured query language that has the following benefits:
  • It has a pretty easy to write and read syntax.
  • It is very efficient in manipulating, updating, and querying relational databases. 
• Java: Java has fewer libraries and its verbosity is limited, but it has certain advantages:
  • There are several systems that are already coded in Java at the backend. This makes the integration of data science projects to these systems easy. 
  • It is a general purpose, high-performance, and a compiled language. 
• Scala: It is a preferred language in data science even though it has a complex syntax because of the following reasons:
  • The language runs on JVM that makes it compatible with Java as well.
  • If the language is used with Apache Spark, we can get high-performance cluster computing.

Here is how you can download and install Python 3 on Windows:

Download and setup: Visit the download page and use the GUI installer to setup Python on your windows. Make sure that while you are installing, you select the checkbox asking to add Python 3.x to PATH. This is your classpath that will allow you the usage of Python's functionalities from the terminal.

You can also use Anaconda to install Python. If you want to check if Python is installed, you can try using the following command that will show the current version of Python installed:

python --version

• Update and install setuptools and pip: If you want to install and update the crucial libraries, you can use the following command:

python -m pip install -U pip

Note: You can create isolated Python environments and pipenv using virtualenv. Pipenv is a Python dependency manager. 

For installing Python 3 on Mac OS X, you can either simply install the language from their official website using a .dg package or use Homebrew python or its dependencies. Here are the steps you need to follow:

1. Install Xcode: First, you need to install Xcode. You will need the Xcode package of Apple/ Start using the following command: $ xcode-select --install
2. Install brew: Next, you have to install Homebrew which is a package manager for Apple. Start with the following command:/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" Confirm if it is installed by typing: brew doctor
3. Install python 3: Lastly, to install python, use the following command: brew install python

• If you want to confirm the version of python, use the command: python --version

You should install virtualenv that will create isolated places for you to run different projects and can even run different versions of Python on different projects.
