All You Need to Know About Learning Data Science with Python

Whether you’re an aspiring data scientist or you’re already a data scientist looking to expand your skill set, know that the knowledge of Python is an essential skill in the field of data science. Python has become the preferred language in data analysis over the last few years, and it’s mainly due to its ease of learning and the fact that it is hugely time saving during application, though those are not the only reasons. Listed below are five reasons Data Science with Python training is essential for every data scientist. But, before we get to the why of learning this programming language, let’s understand what Python is.

What is Python?

Python is a versatile programming language that supports functional programming, structured programming, and also object Oriented programming. The versatility of this language is what makes it a good choice for data scientists. Python enables developers to create codes in a modular style and the codes can be reused as well, since Python supports the use of modules and packages.

Python is a simple and easy to learn programming language. It requires the use of a unique syntax which supports readability. It’s also a low-cost programming language. Python’s interpreter and standard library are available free of cost in binary and source form.

Python for Data Scientists

According to the Indeed Data Science skills report of April 2019, Python is among the top skills employers look for in data scientists, along with machine learning and SQL and Hadoop.Having these top skills not only boosts your resume but also gives you the chances of earning a higher salary. According to LinkedIn, data scientists with an updated skillset make an average of $107,000 a year.

Here are the top five reasons why you should take data science with Python training.

Scalable

Python is more scalable than R, making it more and more popular across various industries. It is also faster than Matlab and Sata. YouTube is one platform that uses Python because of its flexibility in problem solving situations.

Compatible with Hadoop

Python is compatible with Hadoop, the most popular open-source big data platform. The PyDoop package offers access to HDFS API for Hadoop, allowing programmers to write Hadoop MapReduce programs and applications. HDFS API allows you to connect to HDFS installation, which makes it easy to read, write, and get information on global file system properties, directories, and files.

Easy to Learn

Python is easy to learn for non-programmers too, compared to other programming languages. Due to its readable code, large online community, and varied learning resources, Python is a good choice to start learning programming language.

Extensive data science libraries

Python has over 72,000 libraries in the Python Package Index, making it popular among aspiring candidates. These libraries are upgraded regularly. Most of the libraries in Python are available for data analysis. Here are some of them.

  • NumPy: The library has a number of high-level mathematical functions that operate on multidimensional arrays and matrices.
  • SciPy:  It works in association with NumPy arrays and has routines for numerical integration and upgradation.
  • Matplotlib: This is a 2D plotting library which contains data visualizations in the form of histograms, bar charts, and scatterplots with minimal coding lines.

Online Python Community

Python has increased its reach in the world of data science and a large number of volunteers are developing Python libraries. Due to this, it’s possible to develop advanced tools and processes in Python.

Which Skills Will You Learn?

Python is simple to learn, making it an ideal learning language for beginners. Read on to know which other skills you will learn with the data science with Python course.
