How to Learn Python for Data Science

Python for data science novices often find it challenging when they try to determine the best way to master the popular programming language. Whereas busy professionals may already have some data science skills, students beginning their careers may want to get in-depth training in a concentrated time frame.

Fortunately, Python data science students can find many educational options, both in-person and live online. Bootcamps, certificate programs, and self-paced classes provide information and, in many cases, hands-on experience. Consider the following:

  • Live Coursework - Most Python for data science training students prefer to learn in person or live online through teleconferencing. You can use Noble Desktop’s Classes Near Me tool to compare and contrast all the options, or look for live online courses if you’ve already narrowed your choices to virtual training alternatives.
  • Self-Paced Programs - On-demand or self-paced courses can be helpful if you’re starting out with Python for data science. Some offer training at the beginner level, whereas others require intermediate skills. Check out options like Exchanging Excel for Python or Making a Twitter Bot in Python for more information.

Level of Difficulty, Prerequisites, & Cost 

You may think Python for data science will be challenging to learn, particularly if you have no coding experience. However, many students are surprised to learn that Python is the most popular programming language among data science professionals and one of the easiest to master. Python’s open-source license means an entire universe of libraries can be used free of charge, and its worldwide support community is always a mouse click away.

Before you start learning Python for data science, you should have a plan for how and where you’ll apply the knowledge you gain. Python programming fundamentals for a Data Analyst may differ from those of a Software Engineer. You should have basic computer skills, but you can use Python on Mac OS, Linux, or Windows.

You can download Python’s libraries and frameworks for free and find many online Python seminars and tutorials at no cost. However, you’ll eventually want to enroll in formal, paid training. If you learn Python as part of a broader data science curriculum, your approach will be different than if you want to focus on Python in a narrower sense.

How Does Learning Python for Data Science Compare to Other Languages?

Python is a primary component of data science, but not every data science professional uses it equally. Many programming beginners start with Java or R, but most learn Python before other languages.

In recent years, R has emerged as the other “big” data science language besides Python. While Python may be easier to learn, R has several advantages in the eyes of many data pros. Consider the following:

Python is typically the language of choice for handling large quantities of data. Python is also commonly tied to deep learning algorithms, web scraping, and running workflows. On the other hand, many data science pros prefer R for data visualization and statistical calculation. 

Data Scientists and other computer science pros may prefer Python for many tasks. However, Data Analysts, Financial Analysts, and Business Analysts may use R more. Both have advantages and drawbacks, so you may want to learn both, depending on your role and the sector or industry you choose.
