def get_stock_list(stockListURL):

r =requests.get(stockListURL, headers = headers)

doc = PyQuery(r.text)

list = []

获取所有 section 中 a 节点，并进行迭代

for i in doc(‘.stockTable a’).items():

try:

href = i.attr.href

list.append(re.findall(r"\d{6}", href)[0])

except:

continue

list = [item.lower() for item in list] # 将爬取信息转换小写

return l
