open()方法常用写入方式：

from pyquery import PyQuery as pq

html = requests.get(url, headers=headers).text
print(html)

    question = item.find('h2').text()

    with open('D:/explore.txt','a',encoding='utf-8') as file: #a是直接写入，a换成w时，保存并清空，使用as不用调用close()
        file.write('\n'.join([question,author,answer]))
