Why NumPy is the Fundamental Package for Scientific Computing in Python
NumPy is an open-source Python library widely known for its efficient handling of complex, mathematical operations on large, multidimensional arrays (called ndarrays). To understand why NumPy is so popular, we must first contrast NumPy arrays to Python’s native lists.
Python wasn’t designed with numerical computing in mind. However, what was designed in mind was simplicity and readability. Funnily enough, it was this design decision that drove more and more scientists and engineers to adopt the Python language for their computational work, even though it wasn’t as fast as other harder-to-learn languages. Instead of looking for another alternative, scientists and engineers did what they do best and adapted the language to their needs, resulting in the development of many scientific frameworks and libraries to overcome Python’s inherent sluggishness.
Thus, NumPy was born. By utilizing fixed types, no type checking when iterating through objects, utilization of contiguous memory, effective cache utilization, as well as other optimization techniques, NumPy is now much faster than the standard Python list with a magnitude of 5 to 100 times! And when paired with an efficient Python implementation like Cython, it can even reach speeds up to 1250 times faster!
Taken from Lesson 3 – Numerical Computing with Numpy | Jovian.
Though that wasn’t the only thing NumPy brought to the table. NumPy also provides a wealth of functions that enable complex operations on arrays with just a few lines of code, including mathematical, logical, shape manipulation, discrete Fourier transforms, basic linear algebra, basic statistical operations, random simulation, and much, much more.
All of these reasons combined brought NumPy the versatility and speed needed to become the fundamental package for all scientific computing in Python, and it did. With an astounding 64% of all Python developers using NumPy for data-related tasks, it’s hard to say that it isn’t one of the most widely used Python packages. In fact, it even serves as the base for many other major data science libraries in Python, such as pandas (which is only 5% less popular than NumPy)!
One hidden benefit that brings is that NumPy seamlessly integrates with most other Python libraries as well, like SciPy, TensorFlow, scikit-learn and Matplotlib. Together, these libraries provide a complete data science and scientific computing environment, making it easy for anyone to analyze, visualize, and manipulate data all within a single Python environment!
Hence, whether you’re a data scientist, machine learning engineer, or just someone who needs to crunch a bunch of numbers in a short amount of time, NumPy is definitely worth learning.

Why You Should Trust Us
Class Central, a Tripadvisor for online education, has helped 60 million learners find their next course. We’ve been combing through online education for more than a decade to aggregate a catalog of 200,000 online courses and 200,000 reviews written by our users. And we’re online learners ourselves: combined, the Class Central team has completed over 400 online courses, including online degrees.
Best Courses Guides Methodology
I built this ranking following the now tried-and-tested methodology used in previous Best Courses Guides (you can find them all here). It involves a three-step process:
- Research: I started by leveraging Class Central’s database. Then, I made a preliminary selection of over 480 NumPy courses by rating, reviews, and bookmarks.
- Evaluate: I read through reviews on Class Central, Reddit, and course providers to understand what other learners thought about each course and combined it with my own experience as a learner.
- Select: Well-made courses were picked if they presented valuable and engaging content. They have to fit in a set of criteria: comprehensive curriculum, affordability, release date, ratings and enrollments.
Ultimately, I used a combination of data and my own judgment to make these picks. I’m confident these recommendations will be a reliable way to learn about NumPy.

@Elham, we’re in agreement that “Doing is the best way of learning.” So thanks for including your #10 pick, because the longest course in this Guide is merely 5 hours and some courses are passive (without any independent exercises). I also appreciate your explanations about why I should take each course, especially those noting certain considerations.
