Importance of Data Science
With the proliferation of technology in our everyday lives, businesses need to collect and analyze more data than ever before. Data market demand is high in the market to help businesses make sense of all this data and use insights to make better business decisions. In today’s data-driven world, businesses use data from a wide variety of sources – social media, email, mobile devices, point-of-sale systems, etc. Data scientists need to be able to analyze and interpret all of this data in order to turn it into useful information and derive meaningful insights. Thus, the demand for data scientists is growing rapidly. According to Indeed.com, the number of jobs related to “data science” has increased by over 600% since 2012.
Demand for Python in Data Science
Machine learning or AI is becoming an integral part of virtually every industry in the world. There is tremendous potential for applications of machine learning and AI in various fields including healthcare, transportation, energy, e-commerce, finance, and more. However, powerful AI tools are not always available to the average business due to the high costs associated with building and maintaining these complex systems. Python provides an easy and elegant way for developers to build complex AI applications without having to learn a low-level programming language like C or C++. As a result, Python is becoming a very popular language for data scientists and developers who want to build machine learning-based applications. Here are several examples of companies using Python for machine learning and AI:
- Netflix uses Python to analyze video traffic patterns and provide recommendations for users based on their viewing history.
- Spotify uses Python to design music playlists based on the user’s preferences.
- Google uses Python to cluster search results and organize them in a meaningful manner.
- Uber uses Python to track taxis and update the driver on passenger locations in real-time.
- Airbnb uses Python to build a system that provides recommendations based on guest ratings and feedback.
As you can see, Python is playing an important role in the development of machine-learning-based applications across a range of industries. With the widespread use of Python in data science, there is an increasing demand for talented data scientists who can proficiently use the Python programming language in data analysis projects. If you want to become a data scientist but don’t know how to use Python, we recommend that you take a course in Python programming from a reputable training provider such as Udemy, Coursera, or Pickl.AI.

Why is Python used in Data Science?
In terms of ease of use, Python is well-known for its clear syntax and readable code. This makes Python a preferred choice for developers who are building deep learning models and other data-driven applications. In addition to being simple to read and write, Python also offers a number of features that make it the ideal programming language for data scientists. These include built-in data structures that make working with large datasets a breeze, a wide range of third-party libraries that you can use in your programs, and powerful data visualization tools that help you present your findings in a visually appealing format.
As the popularity of Python continues to grow, more and more organizations are beginning to implement custom solutions using this programming language. For example, PayPal recently open-sourced a natural language processing framework called Stanford NLP that is powered by Python. This framework makes it easy for developers to build text-processing applications that are able to analyze large volumes of unstructured data and identify actionable insights.
In short, Python is ideal for anyone who is interested in becoming a data scientist because it makes the learning process a lot easier and more straightforward.
