Tuples are one of the core data structures in Python, characterized by their “immutability”—like a sealed gift box, once packed, the internal elements cannot be modified or changed. Below, we will break down the knowledge of tuples from five dimensions: syntax, features, operations, practical applications, and common pitfalls!1. Basic Syntax of Tuples: How to Create … Read more
In Python, data types are divided into basic data types and data structure types. The basic data types in Python include four types: integers, floating-point numbers, booleans, and strings, as detailed in Basic Data Types in Python. Basic data types alone are not sufficient; sometimes, it is necessary to handle data in groups, which requires … Read more
Chapter 9: Compound Data Types In the programming world, data is never isolated. We not only deal with individual numbers or strings but also manage a collection of data, such as a list of student grades, a set of coordinate points, or a collection of user tags. In Python, containers used to store multiple data … Read more

1. Introduction to the enumerate() Function In Python, enumerate is a built-in function that allows you to retrieve both the index and the element itself while iterating over a sequence (such as a list or tuple). Its core function is to automatically add a counter to the iteration process, so you do not need to … Read more
Part One: Overview of Composite Data Types 1.1 What are Composite Data Types Composite data types are data structures that organize multiple data items together, allowing them to store multiple values and providing various methods for manipulating these values. Unlike basic data types (integers, floats, strings, etc.) that can only store a single value, composite … Read more
11. Tuples and Sets In addition to lists and dictionaries, these two data structures are also very common: 1. Tuples (Immutable Sequences) Defined using <span>()</span>, once the elements are set, they cannot be modified (immutable) Suitable for storing fixed data (such as coordinates, configuration items) # Define a tuple point = (10, 20) # Coordinates … Read more
Most programming languages have specific data structures to store sequences of elements indexed by their position: numbered from the first to the last. Previously, we explored Python strings, which are essentially sequences of characters. Next, we will delve into lists. In addition to strings, Python has two other sequence structures: tuples and lists. Both can … Read more
