Python Text File Data Extraction Guide

To extract data from a text file, you can use file operation functions in Python to read the contents of the file and extract the necessary data based on the file format. Here is a simple example code demonstrating how to extract data from a text file:

# 打开文本文件
with open('data.txt', 'r') as file:
    # 逐行读取文件内容
    for line in file:
        # 根据文件内容的格式提取数据
        data = line.split(',')  # 假设数据以逗号分隔
        # 处理提取到的数据
        print(data)

In this sample code, we assume that the data in the text file is comma-separated. We use the split(‘,’) method to separate each line of data by commas into a list, and then print it out.

Depending on the situation, you may need to appropriately handle the text file’s specific format and data structure, such as by using regular expressions for matching, or by using a specific library to parse files of a specific format.
