soup = BeautifulSoup(html, 'html.parser')
maindiv = soup.find('div',class_="JustInPaginationList")

dataset = []

for item in maindiv('a'):
	title = item.find('p').getText()
	url = item['href']
	print(title)
	print(url)
	print()

	dataset.append({'title':title,'url':url})

Answer 1

maindiv应该写成maindiv = soup.find_all('div',class_="JustInPaginationList")

for循环写成：

for items in maindiv:#resultSet
    item=items.find('a')#每个标签为a的节点元素。
    title = item.find('p').text
    url = item['href']
    print(title)
    print(url)
