请问一个爬虫参数问题

用requests.get("get",url,headers=headers,params=querstring)语句报错如下：
respose = requests.get("get",url,headers=headers,params=querstring)
TypeError: get() got multiple values for argument 'params'

其中
querstring = {"type":"movie","tag":"%E7%83%AD%E9%97%A8","page_limit":"50","page_start":"0"}
请问这是为什么？
