r=requests.get(url,headers=headers)
soup = BeautifulSoup(r.text.replace('<b>', '').replace('</b>', ''),'lxml')
print(soup.find(id="3").find('a', 'c-showurl').string)
#for i in range(1, 11):
#    print(soup.find(id=i).find('a', 'c-showurl').string)

问题主要在最后三行，如果find(id="3")就行find(id=i)就报错，请问如何解决？
还有个问题，就是为何通过python取的搜索结果与电脑搜索到的结果不同？
