In addition, Python experts use data wrangling techniques to manipulate raw data so that it is fit for analytics.
Python’s open-source libraries let data scientists carry out these tasks. Python has many libraries that are regularly updated. NumPy, Pandas, and Matplotlib are among the best ones for data analysis and visualization.
You can learn NumPy and Pandas easily, as long as you are familiar with applying some mathematical formulas, running some statistical equations, and cleaning up data. For example, it takes only a few minutes to learn how to import a Python module. If you are wondering which Python module to use for a specific job, just Google it. You’ll find the information you need.
Python is very popular among data analysts, which means you have an active community of people to turn to if you get stuck during a project. With the support of this community, you can master this language and its most complex libraries.
If you want to get into data analysis, you won’t get far without knowing some Python. Many companies rely on this language to build their frameworks. For instance, Facebook and Netflix are increasingly using it for their data analysis projects. Additionally, Google is the creator of TensorFlow, a popular Python library used in machine learning and artificial intelligence.
A career in Python is more stable than many other tech occupations. This language has been around for thirty years and it’s constantly adapting to fit new market needs. Your career goals might change and the job market may experience a decline, but knowing Python will always be a useful skill that will make you more employable.
If you develop expertise in Python and are able to apply it to the field of data analytics, you can become a data analyst. According to the US Bureau of Labor Statistics, the job outlook for data analysts is 25 percent from 2020 to 2030, which is much faster than average.
