使用正则表达式爬取雪球网页中的市盈率-(代码中变量：shiyinglv)属性时无法得到正确值，始终得到空列表

try:

    r = requests.get(url, timeout = 30,headers=headers)

    r.raise_for_status()

    r.encoding = r.apparent_encoding

    print(r.encoding)

    return r.content

except:

    return ""Copy

html = getHTMLText(url)

name = re.findall('<div class="stock-name">(.*?)</div>',html.decode('utf-8'))

price = re.findall('<div class="stock-current"><strong>¥(.*?)</strong>',html.decode('utf-8'))

shiyinglv = re.findall('市盈率(动): <span>(.*?)</span>',html.decode('utf-8'))

print(name,price,shiyinglv)Copy
