Kursbeskrivning

Explore Python's Data Science package: NumPy

Gain an introduction to Numpy and understand why this Python library is essential to all Python data scientists and analysts. Most importantly, learn more about Numpy arrays and how to create and change array shapes to suit your needs.

Discover NumPy Arrays

NumPy is an essential Python library for data scientists and analysts. It offers a great alternative to Python lists, as they are more compact and allow faster access to reading and writing items, making them a more convenient and efficient option.

In this Introduction to NumPy course, you'll become a master wrangler of NumPy's core object: arrays! Using New York City's tree census data, you'll create, sort, filter, and update arrays. You'll discover why NumPy is so efficient and use broadcasting and vectorization to make your NumPy code even faster.

Gain Confidence by Practicing on the Monet dataset

By the last chapter, you will use your newly acquired knowledge to perform array transformations. You will use image 3D arrays to alter a Claude Monet painting and understand why such array alterations are essential tools for machine learning.

You will gain confidence in Numpy arrays and their different operations upon course completion. This course is part of the Data Scientist with Python track and is perfect for those seeking a Data Science certification with DataCamp.

Förkunskapskrav

Intermediate Python

1

Understanding NumPy Arrays

Meet the incredible NumPy array! Learn how to create and change array shapes to suit your needs. Finally, discover NumPy's many data types and how they contribute to speedy array operations.

Introducing arrays

Your first NumPy array

Creating arrays from scratch

A range array

Array dimensionality

3D array creation

The fourth dimension

Flattening and reshaping

NumPy data types

The dtype argument

Anticipating data types

A smaller sudoku game

2

Selecting and Updating Data

Sharpen your NumPy data wrangling skills by slicing, filtering, and sorting New York City’s tree census data. Create new arrays by pulling data based on conditional statements, and add and remove data along any dimension to suit your purpose. Along the way, you’ll learn the shape and dimension compatibility principles to prepare for super-fast array math.

Indexing and slicing arrays

Slicing and indexing trees

Stepping into 2D

Sorting trees

Filtering arrays

Filtering with masks

Fancy indexing vs. np.where()

Creating arrays from conditions

Adding and removing data

Compatible or not?

Adding rows

Adding columns

Deleting with np.delete()

3

Array Mathematics!

Leverage NumPy’s speedy vectorized operations to gather summary insights on sales data for American liquor stores, restaurants, and department stores. Vectorize Python functions for use in your NumPy code. Finally, use broadcasting logic to perform mathematical operations between arrays of different sizes.

Summarizing data

Sales totals

Plotting averages

Cumulative sales

Vectorized operations

Tax calculations

Projecting sales

Vectorizing .upper()

Broadcasting

Broadcastable or not?

Broadcasting across columns

Broadcasting across rows

Array Transformations

NumPy meets the art world in this final chapter as we use image data from a Monet masterpiece to explore how you can use to augment image data. You’ll use flipping and transposing functionality to quickly transform our masterpiece. Next, you’ll pull the Monet array apart, make changes, and reconstruct it using array stacking to see the results.

Saving and loading arrays

Loading .npy files

Getting help

Update and save

Array acrobatics

Augmenting Monet

Transposing your masterpiece

Stacking and splitting

2D split and stack

Splitting RGB data

Stacking RGB data

Congratulations!
