Focuses on the latest large-model trends, applications, technical architectures, and related information.
This tutorial walks through using Python's urllib and regular expressions to crawl a Baidu Tieba page, extract all .jpg image URLs, and download each image locally with a sequential naming scheme.
This tutorial walks through creating a Python script that opens a text file, reads its contents, prints them, then demonstrates how to overwrite the file with new text, explaining each step, the importance of closing files, and additional file‑operation commands such as readline, truncate, and write.
This guide demonstrates how to define a Python list, print its contents, and iterate over each element using both a for‑loop and a while‑loop, including step‑by‑step code explanations and common pitfalls such as infinite loops and type conversion.
This tutorial shows step‑by‑step how to define Python functions with parameters, call them with string arguments, return numeric results, capture those results in variables, and print them, illustrating the core mechanics of function inputs and outputs.
This guide explains how Python scripts receive command‑line arguments as a list via sys.argv, how the import statement brings in the needed module, and how assigning argv to a variable effectively unpacks the arguments for further processing.
This tutorial walks through Python list fundamentals, showing how to define a list, retrieve elements by index, update a specific item, remove an element, and append new items, while explaining the underlying indexing rules and the benefits of using a single container for multiple strings.
This tutorial walks through Python’s built-in input() and print() functions, shows how to capture user input, format it with the % operator, and then demonstrates creating and invoking a simple custom function while stressing proper indentation, all illustrated with code snippets and screenshots.
This article introduces Python's string formatting operators, explains how %r converts values to strings and %d formats integers, and demonstrates their usage with concrete code examples and output, guiding beginners through building formatted messages step by step.
This tutorial explains how variables act as named placeholders for data, demonstrates assigning numeric values, performing arithmetic, and concatenating strings through clear Python code snippets, and shows the expected output for each example to help beginners grasp variable usage.
This tutorial walks through Python’s arithmetic and comparison operators, shows exact code snippets and their outputs, explains why Boolean results appear as True or False, and then introduces single‑line and multi‑line comment syntax with clear demonstrations.
