Beginner's Series to: Django
by Microsoft

One of the most popular types of web applications to create is one to act as a front-end for a database. These applications focus on a common set of patters where you will allow users to create, retrieve, update and delete (CRUD) data. Creating CRUD applications can sometimes be tedious as large portions of the code are duplicated in your project.

ENJOY LEARNING 👍👍

Question: What are Python set comprehensions?

Answer:Set comprehensions are similar to list comprehensions but create a set instead of a list. The syntax is:

{expression for item in iterable if condition}

For example, to create a set of squares of even numbers:

squares_set = {x**2 for x in range(10) if x % 2 == 0}

This will create a set with the values

{0, 4, 16, 36, 64}

Eigenvalues & Eigenvectors — Why PCA Actually Works

You’ve heard of PCA. But what’s really happening underneath?

PCA finds the directions (vectors) where your data varies the most.

Those directions are eigenvectors of the covariance matrix and the eigenvalues tell you how much variance each captures.

You’re basically rotating your data to find its “natural axes.”

PCA isn’t compression — it’s discovering how your data wants to be seen.
