本文主要是介绍Python爬虫某云音乐歌手及下载其免费音乐，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
import os import re import threading import timefrom lxml import etreeimport requests from bs4 import BeautifulSoup from database import MyDataBase from utils import make_user_agent
注意：database和utils是自己写的。没有注释，不懂就问
先运行CrawlWangYiYunSinger，不然数据库没有歌手的表！！！！！！！！！！！！！
大概几万个，很快下载完
utils.make_agent()返回的是{"Agent":"..."}
database数据库的包,复制即用：Python操作Mysql数据库-CSDN博客

一、日志
方便查看爬取情况
class Logger:def __init__(self, path):self.path = pathself.log_path = path + "/logs.txt"self.create()def create_parent(self):if not os.path.exists(self.path):os.makedirs(self.path)def create(self):self.create_parent()if not os.path.exists(self.log_path):with open(self.log_path, "w", encoding='utf-8') as f:passdef clear(self):with open(self.log_path, "w", encoding='utf-8') as f:passdef delete(self):os.remove(self.log_path)def info(self, content):with open(self.log_path, "a", encoding="utf-8") as f:t = time.strftime("[%Y-%m-%d %H:%M:%S]")s = f"{t}\t{content}"f.write(f"{s}\n")print(s)二、爬取歌手到数据库
