Article Introduction：Processing unstructured data in C++ involves data preprocessing, feature extraction, and model training. Processing semi-structured data includes data parsing, extraction and transformation. The specific steps are as follows: Unstructured data: Data preprocessing: noise removal and normalization. Feature extraction: Extract features from data. Model training: Use machine learning algorithms to learn patterns. Semi-structured data: Data parsing: conversion into appropriate formats (XML, JSON, YAML). Data extraction: Get the information you need. Data conversion: into a format suitable for further processing.

Article Introduction：Data structure includes three aspects: linear structure, tree structure and graphic structure. Detailed introduction: 1. Linear structure is one of the simplest and most common data structures. There is a one-to-one relationship between data elements in the linear structure, that is, each element has only one direct predecessor and one direct successor. The linear structure Common implementation methods include arrays, linked lists, stacks and queues; 2. The tree structure is a non-linear data structure, which consists of nodes and edges. There is a one-to-many relationship between the nodes in the tree structure, that is, each A node can have multiple child nodes and so on.

Article Introduction：List: A collection that stores ordered elements. Tuple: An immutable collection that stores ordered elements. Set: A collection that stores unordered and non-repeating elements. Dictionary (dict): A collection that stores key-value pairs. 3. Data structure Data structure is a way of organizing data for efficient storage, retrieval and processing of data. Python provides built-in data structures, including: array: a linear data structure that efficiently stores elements of the same type. Linkedlist: a linear data structure that uses pointers to link elements. Stack: follows the last-in-first-out (FILO) principle. Linear data structure queue (queue): a linear data structure that follows the first-in-first-out (FIFO) principle
