If you're looking to grow your career in machine learning or data science in this day and age, adding a powerful library to your skill set is an important place to start. In that vein, Python has become one of the most widely used tools in the industry for serious data analytics, and NumPy is probably the most widely used data analytics library. With NumPy, you can manipulate data involving multi-dimensional arrays and matrices (think linear algebra).

Join us as we venture into the vast world of NumPy in this comprehensive course. Each lesson dive into the actual implementation of concepts in both pure Python and then NumPy, exploring how NumPy vectorization compares to traditional Python that uses a procedural and object-oriented approach.

Practice and test yourself along the way with in-browser coding challenges, quizzes, and more.

This course is intended for users who are already familiar with intermediate level Python.

From Python to Numpy

### Boid Class Implementation (Python)
Since each boid is an autonomous entity with several properties such as position and velocity, it seems natural to start by writing a `Boid` class:

# Boid Class Implementation (Python)
Since each boid is an autonomous entity with several properties such as position and velocity, it seems natural to start by writing a `Boid` class:

In this lesson we will try to implement the Boids class using the traditional Pythonic approach and analyze it in terms of efficiency.
