推荐答案

src在 img 标记中:

from bs4 import BeautifulSoup
tag = """<a class="itemImage" href="http://www.newegg.com/Product/Product.aspx?Item=N82E16875169194&amp;cm_re=Samsung_edge-_-75-169-194-_-Product" id="img_75-169-194" title='Samsung Galaxy S7 Edge Dual SIM Unlocked Smart Phone, Dual Edge 5.5" AMOLED Display, black Color, 32GB Storage 4GB RAM International Version - No US Warranty'>\n<img alt='Samsung Galaxy S7 Edge Dual SIM Unlocked Smart Phone, Dual Edge 5.5" AMOLED Display, black Color, 32GB Storage 4GB RAM International Version - No US Warranty' src="http://images10.newegg.com/ProductImageCompressAll200/75-169-194-04.jpg" title='Samsung Galaxy S7 Edge Dual SIM Unlocked Smart Phone, Dual Edge 5.5" AMOLED Display, black Color, 32GB Storage 4GB RAM International Version - No US Warranty'/>\n</a>"""

soup = BeautifulSoup(tag,"lxml")

src = soup.img["src"]

哪个会给你:

http://images10.newegg.com/ProductImageCompressAll200/75-169-194-04.jpg
