Python多线程爬取图片

以下是Python多线程爬取图片的代码示例：

import requests
from bs4 import BeautifulSoup
import threading

def download_image(url, filename):
    response = requests.get(url)
    with open(filename, "wb") as f:
        f.write(response.content)

def crawl_images(url):
    response = requests.get(url)
    soup = BeautifulSoup(response.content, "html.parser")
    images = soup.find_all("img")
    for i, image in enumerate(images):
        image_url = image["src"]
        filename = "image{}.jpg".format(i)
        t = threading.Thread(target=download_image, args=(image_url, filename))
        t.start()

if __name__ == "__main__":
    url = "https://www.example.com"
    crawl_images(url)

该代码首先定义了一个`download_image`函数用于下载图片，然后定义了`crawl_images`函数用于爬取图片链接，并创建多线程下载图片。最后，使用`if __name__ == "__main__":`语句调用`crawl_images`函数，传入需要爬取的网站URL。
