返回这样的错误，是什么原因，可以给我解释一下吗，谢谢大家

',' or ')' expected15行
':' expected 15行
':' expected16行
即下面这两行
for i in re.findall("<meta name="description"content="[\d\D]+。" />",html):
for c in re.findall("t="[\d\D]+"",i):

import requests
import re
import jieba
import json
fg = 1
f = []
urll = "https://so.gushiwen.cn/gushi/tangshi.aspx"
headers = {"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:90.0) Gecko/20100101 Firefox/90.0"}
html = requests.get(urll, headers=headers).text
hh = re.findall("/shiwenv_[\d\D]{17}", html)
for fff in hh:
url = "https://so.gushiwen.cn" + fff
html = requests.get(url, headers=headers).text
for i in re.findall("<meta name="description"content="[\d\D]+。" />",html):
for c in re.findall("t="[\d\D]+"",i):
e = c[3:len(c) - 1]
aa = jieba.lcut(e)
for d in aa:
if d != "，" and d != "。" and d != ":" and d != "!" and d != "？" and d != "（" and d != "）" and d != "(" and d != ")" and d != "：" and d != " ":
f.append(d)
print("第" + str(fg) + "首诗文分析成功")
fg += 1
with open("data.json", mode='w', encoding="utf-8") as fd:
fd.write(json.dumps(f, ensure_ascii=False))

因为你字符串里面的双引号跟外面的双引号冲突了，把字符串外面的双引号改成单引号就行

import requests
import re
import jieba
import json
fg = 1
f = []
urll = "https://so.gushiwen.cn/gushi/tangshi.aspx"
headers = {"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:90.0) Gecko/20100101 Firefox/90.0"}
html = requests.get(urll, headers=headers).text
hh = re.findall("/shiwenv_[\d\D]{17}", html)
for fff in hh:
url = "https://so.gushiwen.cn" + fff
html = requests.get(url, headers=headers).text
for i in re.findall('<meta name="description"content="[\d\D]+。" />',html): # 改了这行
for c in re.findall('t="[\d\D]+"',i): #改了这行
e = c[3:len(c) - 1]
aa = jieba.lcut(e)
for d in aa:
if d != "，" and d != "。" and d != ":" and d != "!" and d != "？" and d != "（" and d != "）" and d != "(" and d != ")" and d != "：" and d != " ":
f.append(d)
print("第" + str(fg) + "首诗文分析成功")
fg += 1
with open("data.json", mode='w', encoding="utf-8") as fd:
fd.write(json.dumps(f, ensure_ascii=False))
