import requests as res
from bs4 import BeautifulSoup as bs
def body_function(url):
resp = res.get(url)
tex = resp.text
soup = bs(tex,'lxml')
status = resp.status_code
if status == 200:
return soup
def price_infor(html):
goods_jiage = html.find_all(class_='product-price')
for result_gj in goods_jiage:
ru1_1 = result_gj.find_all(class_='price-num')#获取卷后价格
for ru1 in ru1_1:
rus1 = ru1.get_text()
return rus1#用return返回结果时，无法返回所有结果，我知道print可以，但是无法拼接其他函数的返回结果
def baochou_infor(html):
goods_quan_info = html.find_all(class_='quan-infro')
for result_gqi in goods_quan_info:#获取佣金价格
ru2 = result_gqi.select('em')
ru2_1 = result_gqi.find('a')
rus2 = ru2_1['href']
n1 = list(ru2[0])
n2 = list(ru2[1])
ns = n1+n2
#print ('优惠卷：'+ns[0]+'元'+' 返现比例：'+ns[1]+'%'+' 优惠券链接：'+rus2)
def main():
headers = {
'User-Agent':'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) '
'Chrome/64.0.3282.186 Safari/537.36'}
key = input("please input the keywords:")
page_num = int(input("input the pagenumber:"))
for pg in range(page_num):
url = 'http://www.taokezhushou.com/search?q='+key+'&page='+str(pg+1)
html = body_function(url)
a1 = price_infor(html)
print(a1)
#a2 = baochou_infor(html)
if __name__ == '__main__':
main()

用return返回结果，然后调取函数的时候得出全部的结果，我知道用print可以，用print输出结果会导致结果没办法和其他结果拼接在一起，就大神解答
