Args and Kwargs Python

Python / By Chandni Arora

Args and kwargs Python are special keywords used in function definitions to allow a variable number of arguments to be passed. The args syntax handles non-keyworded, variable-length argument lists, while kwargs manages keyworded, variable-length dictionaries. These tools provide immense flexibility, enabling developers to create functions that adapt to different amounts of input data dynamically. Args …

Python Pass Statement

Python / By Chandni Arora

Python Pass Statement is a null operation used as a placeholder in code blocks where a statement is syntactically required but no action is needed. It allows developers to create empty classes, functions, or loops during the initial development phase without triggering errors. Unlike comments, the pass statement is executed by the interpreter but results …

Filter in Python

Python / By Chandni Arora

Filter in Python is a built-in function that allows you to process an iterable and extract only those elements that satisfy a specific condition. It takes a function and an iterable as arguments, returning an iterator. This tool is essential for data cleaning, as it efficiently removes unwanted items based on the logic provided in …

Reduce in Python and Filter Explained

Python / By Chandni Arora

Reduce in Python is a functional programming function that applies a specific rolling computation to sequential pairs of elements in an iterable. By using a binary function, it processes the first two items, takes that result, and combines it with the third item, continuing until only a single cumulative value remains. It is part of …

Branch and Bound Algorithm

DSA / By Chandni Arora

Branch and Bound Algorithm is a systematic method for solving combinatorial optimization problems by exploring all possible solutions in a state-space tree. It works by “branching” the problem into smaller sub-problems and using a “bound” function to estimate the best possible solution in each branch. This allows the algorithm to prune or discard branches that …

Graph Data Structure

DSA / By Chandni Arora

Graph Data Structure is a non-linear data organization consisting of a finite set of nodes, also known as vertices, and a set of edges that connect these vertices. Graphs are used to represent complex relationships and networks, such as social connections, city maps, or the internet. Graph Data Structure Have you ever wondered how Google …

The Guide to the Sliding Window Technique

DSA / By Chandni Arora

The Sliding Window Technique is a smart way to solve puzzles that use a list of items. Imagine you have a very long row of numbered blocks stretching across your room. If someone asks you to find the total of any three blocks standing next to each other, you might start by adding the first …
