Dynamic Array Implementation Python lists are implemented as dynamic arrays thatt automatically resize when elements are added or removed. The underlying mechanism uses contiguous memory allocation with over-allocation strategies to optimize performence. When a list exceeds its current capacity, Pyt...
Overview of Sequences Python provides several sequence types, with strings, lists, and tuples being the most common. Lists and tuples share similar syntax but differ fundamentally in mutability: tuple are immutable once defined, while lists can be modified dynamically. Creating Lists and Tuples List...
Hyperlinks The anchor tag <a> creates navigable links to external resources or internal page sections. The href attribute specifies the destination URL, while the target attribute controls how the linked document opens. <!DOCTYPE html> <html lang="en"> <head> <meta charse...
Lists Lists represent ordered, mutable sequences capable of storing heterogeneous elements. Elements within a list can be duplicated. Creation and Initialization inventory = [] inventory = ['item_x', 'item_y'] inventory = list() Accessing Elements Indexing allows direct access to elements. Positive...
Lists A list is an ordered collection of elements that can hold items of different types. Key characteristics: Elements: Can be of any data type. Order: Maintains a specific sequence. Creating Lists There are two primary ways to create lists: Method 1: Initialize an empty list and add elements one b...
Arithmetic Operations on Numbers Basic operations include addition (+), subtraction (-), multiplication (*), and division (/). Use floor division (//) for integer results (rounds down). Modulo (%) returns the remainder. Functions: abs(x) for absolute value, max(x, y)/min(x, y) for extrema, pow(x, y)...
