如何部分重新连接解析后的URL？

from urllib.parse import urlparse, parse_qs

url = "https://www.example.com/search?q=keyword&page=1"
parsed_url = urlparse(url)
query_params = parse_qs(parsed_url.query)

query_params['q'] = ['new_keyword']
query_params['page'] = ['2']

new_query_string = '&'.join([f"{key}={value[0]}" for key, value in query_params.items()])
new_url = f"{parsed_url.scheme}://{parsed_url.netloc}{parsed_url.path}?{new_query_string}"

# 使用new_url进行后续操作，如发送HTTP请求获取数据
