In Python, everything is an object. Even integers are objects — this is different from programming languages like Java where integers, floats, and Booleans are primitive data types. In this way, Python is built on a rigorously consistent object-oriented paradigm. Considering that objects are everywhere in Python, object-oriented programming is not well studied by Python … Read more
A common problem people often run up against in Python is understanding a method to sort one list based on the values in another. There are many solutions to this but I will select three main methods, one of which uses well-understood Python built-in functions such as zip() and sorted(). One will use the dictionary … Read more

Python’s S.symmetric_difference(T) method creates and returns a new set containing all elements that are in exactly one of the two sets S and T. Here’s a minimal example where we return a new set containing the elements 1 and 4 that are in exactly one of the two sets s and t. Here’s another visual … Read more
Quick Answer: Static attributes are variables defined once for the class and shared by all instances. Dynamic attributes are variables defined for individual instances only. Static variables are used as a “fall-back” when there are no explicit dynamic attributes defined for the instances. When you try to “overwrite” a static attribute such as in x.attr … Read more

Are you confronted with a JSON file and at a loss to know how to extract wanted information, or you don’t know about JSON but would like to? Today we’ll introduce the JSON format and use Python to access a JSON file. We’ll extract the data we need and we’ll use the Python JSON module … Read more
Summary: This blog explains the ways to apply a given function to each element of a list. The best way to apply a function to each element of a list is to use the Python built-in map() function that takes a function and one or more iterables as arguments. It then applies the function to … Read more
Python’s set.remove(x) method removes an element x from this set if it is a member, otherwise it raises a KeyError. Here’s a minimal example where you remove the string element ‘Bob’ from the set by means of the s.remove() method: Syntax Let’s dive into the formal syntax of the set.remove() method. set.remove(element) Argument Data Type … Read more
