Understanding The Numpy Mindset • Numerical Python




What you'll learn
Learn the fundamentals of Python's NumPy package
Understand the mindset needed to work with NumPy
Learn to create and use NumPy's ndarray object
Use NumPy in real-world examples
Requirements
You should be familiar with Python fundamentals such as control statements, defining functions, using data structures such as lists
Description
This is a concise course that covers the fundamentals of Python's NumPy package. Most students who learn NumPy for the first time say that it feels different from the core Python they learnt. And they're right.NumPy requires a different mindset. There's a reason why NumPy does things differently and if you understand why things are the way they are in NumPy, the rest of your NumPy journey will be easier.This course doesn't try to cover everything in the NumPy package. That's impossible and not desirable. Instead, I designed this course to be concise and to focus on what really matters:Understanding the core topics in NumPyUnderstanding the NumPy mindsetThis course covers the following topics:NumPy's main data structure, the ndarrayVectorisation in NumPyArrays in higher dimensionsThe basics of broadcastingFiltering NumPy arrays using Boolean operations and Boolean indexingReading external data using NumPyRepresenting equations with NumPyAnd of course, throughout the whole course you'll get familiar with the NumPy mindset.---About me, your instructorI've been teaching Python and NumPy for a decade. Before that, I worked as a physicist and used numerical and scientific programming in my research work for over a decade.My focus is on communicating clearly, in a friendly and relaxed manner. I'm the author of the The Python Coding Book (you can ask Google for a "python book" and you'll find this book as one of the first entries) and I have taught Python to individuals and corporations around the world.And I'm approachable. You can ask me questions and I'll always reply, whether here on social media or anywhere else you can find me!
