<span class="currentPrice-3131760660"><span content="800.00">800,00 $</span>

我正在尝试自动提取价格(在这种情况下为800 $).但是，随着时间的流逝，"currentPrice-"之后的数字发生了变化，并且我的Python脚本停止工作.我正在使用此美丽汤功能:

I'm trying to automatically extract the price (800$ in this case). Over time, however, the number after "currentPrice-" changes, and my Python script ceases to work. I am using this Beautiful soup function:

soup.find_all('span', {'class' : 'currentPrice-3131760660'})

如何使用find_all提取类名称的部分匹配项，例如包含字符串"currentPrice-"的所有类?

How can I use find_all to extract partial matches of class names, such as all classes containing the string "currentPrice-"?

推荐答案

您可以尝试CSS选择器soup.select('span[class*="currentPrice-"]')

You could try a CSS selector soup.select('span[class*="currentPrice-"]')
