你的代码存在一个语法错误。在 `res = requests.get(` 这一行上，缺少了一个右括号。

要修复这个错误，只需在该行的末尾添加一个右括号即可。以下是修正后的代码：

import requests
import time

headers = {
  'user-agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.132 Safari/537.36',
  'referer': 'http://fund.eastmoney.com/400015.html?spm=search'
}

params = {
"scheme": "http",
"host": "api.fund.eastmoney.com",
"path": "/f10/lsjz",
"query": {
"callback": "jQuery18303118265739643302_1690164521076",
"fundCode": "400015",
"pageIndex": "6",
"pageSize": "20",
"startDate": "",
"endDate": "",
"_": "1690165052233"
}
}

res = requests.get(
  'http://fundf10.eastmoney.com/jjjz_400015.html.api',
  params=params,
  headers=headers)

LSJZ = res.json()['Data']['LSJZList']
for i in LSJZ:
  print("单位净值：",i['DWJZ'])

修正后的代码将不再报错，并且可以正常执行请求和打印单位净值。
