Why Python is good for Data Science?

The numbers don't lie. According to recent studies, Python is the most loving programming language for data scientists. You need a user-friendly language that provides adequate library availability and excellent community participation. Projects with inactive communities are generally less likely to have their platforms serviced or updated, which is not the case with Python.

What makes Python great for data science? We explored why Python is so common in the booming data science industry - and how you can use it in your big data and machine learning projects.

Why Python is best for Data Science?

Most of the programmers used python for the data science because python is easy to use and its syntax is very easy to understand.

Python has long been known as a programming language that is syntactically easy to understand anyway. Python also has an active community with a huge selection of libraries and resources. The result? They have a programming platform that makes sense for new technologies such as machine learning and data science.

Professionals who work with data science applications do not want to get stuck in complex programming requirements. You want to use programming languages ​​like Python and Ruby to perform easy tasks.

Ruby is great for tasks like cleaning and merging data, as well as other data preprocessing tasks. However, there aren't as many machine learning libraries as Python. This gives Python the edge in data science and machine learning

With Python, developers can also deploy programs and run prototypes, which speeds up the development process. Once a project becomes an analysis tool or application, it can be ported to more complex languages ​​such as Java or C if necessary.

New data scientists are attracted to Python because of its ease of use, which makes it accessible. So popular, in fact, that 48% of data scientists with five years or less experience-rated Python as their preferred programming language.

This number gradually decreases with increasing level of experience and the analyses become more intensive. Python has proven to be a great place to start for data scientists

Why Data Science and Python Good to use Together

In data science, useful information is extrapolated from huge pools of statistics, registers, and data. These data are generally unsorted and difficult to correlate with significant accuracy. Machine learning can link different data sets but requires serious sophistication and computing power.

Python fulfills this need by being a universal programming language. You can use it to create a CSV output for easy reading of data in a table. Alternatively, more complicated file output that machine learning clusters can include for computation.

Consider the following example:

The weather forecast builds on previous records from a century of weather data. Machine learning can create more accurate forecast models based on past weather events. Python can do this because it is easy and efficient for code execution, but also multifunctional. In addition, Python can support object-oriented, structured and functional programming styles so that it can be used anywhere.

The Python package index now contains over 70,000 libraries and that number continue to grow. As already mentioned, Python offers many libraries that are geared toward data science. A simple Google search shows many Python top 10 libraries for data science lists. We could say that the most popular data analysis library is an open-source library called Pandas. It is a collection of high-performance applications that make analyzing data in Python a much easier task.

Regardless of what scientists want to do with Python, be it predictive causal analysis or prescriptive analysis, Python has the toolbox to perform a variety of powerful functions. No wonder data scientists have adopted Python.

Conclusion:

I hope now you have understood why most data scientists are using python. NearLearn provides the best data science with python training in Bangalore. it also provides Artificial Intelligence, Machine

What Gives More Benefit to Get Data Science Job – Certification or Project?

 

Data science jobs are increasing day by day and the job seeker are doing certification and projects to get a good data science job. There are number of institute are available that provide data science Classroom Training in Bangalore. But what gives more benefit to get data science job. Would it be certification or project?

There is no question that it is imperative to use all platforms and tools to stand out from others. A prospective data seeker should also set priorities and choose the best approach. Nowadays, however, aspirants use many strategies at random, without having a clear vision of the desired goal, which only leads to burnout.

Main problem is that many aspirants cannot resolve is having more certifications or working on multiple projects. For this reason, most of them take part in certifications and rely on the projects that include data science programs in their courses. This allowed applicants to apply for a job, but recruiters cannot find promising data scientists who can able to solve business challenges.

Enhancement in certification

As we can see that there is huge rise in enrollment in certifications. Mostly students are seeking for the data science certification and want to get a good job in this field.

According to a Coursera report, the e-learning platform has seen a huge increase in enrollments in AI and data science courses. Recruiters find it difficult to hire qualified data scientists, which can be seen from the fact that 85% of AI projects fail due to a lack of good candidates. Certifications make the job interview easier, but do not necessarily guarantee jobs.

Parul pandey said in one report that data scientist aspirants post their data science certification in LinkedIn but they don’t post any projects of data science. Aspirants are lacking to get good job in data science because they don’t communicate about their project which can help more them to get a good job. They only focus on certifications. Certification only helps in getting interviews but do not necessarily to get assured job. Job will be assured only after working in projects which will help you to get more technical knowledge.

Data Science Project Importance

Data science projects are the most important thing for the data science aspirants because it helps to increase their technical knowledge.

But if I talk about the different organizations they all not deal with the same difficulties. Different organizations having different projects and different projects have their own limitations. So aspirants have to face difficulties during their project execution. To tackle these problems aspirants must participate in hackathon challenges where they can show their expertise and enhance their technical skills. Still, aspirants can able to diversify their portfolio by working on a wide range of projects.

With this aspirants should also have the ability to convert the business challenges into the data science problems. As I told you already that certificates help only to get an interview but the projects demonstrate to you how proficient you are to tackle real-world problems which certificate can never do.

Viewpoint

However, as per Sharath Kumar, a data scientist at IBM, with technical skills communication skills also matters. Without communication skills, it is hard to explain the projects to the teammate which will degrade you in that environment. So the communication skills play the vital role for the aspirants in the organization as a data scientist. So they must work on their communication skills as well.

However, certification has their own advantage because by looking that certification only recruiters call you for the interviews but the good number of projects with decent communication skill will help you to crack that interview. So the consequently, aspirant put their efforts on the projects and communicate their projects on the LinkedIn, medium and more which is more beneficial to them rather than only focusing on certifications.

There are number of data science companies are available which will provide you the best data science training in Bangalore with live projects. You can do the data science certification with live training from there and ready to give interviews in different organizations. 

Conclusion

I hope now you have understood that what will help you more to get a good data science job. Near Learn is the top data science training institute in Bangalore that provides the best education in the Bangalore.
