请问如何用正则表达式获取网页中内嵌的JavaScript中的字符串？

Question

var BASE_DATA = {
    headerInfo: {
      id: 0,
      isPgc: false,
      userName: '',
      avatarUrl: '',
      isHomePage: false,
      chineseTag: '视频',
      crumbTag: 'video',
      hasBar: true
    },
    playerInfo: {
      videoId: 'v03004450000bhns5g3jvcldgj685gr0'
    },
  

以上为内嵌在网页中的js代码，我想在pyhon3中用正则表达式获取 videoId 后面的那串字符请问如何获取？用别人写的一直获取不到，请给修改下谢谢~！

reg = r'videoId:(.+?),'
videore = re.compile(reg)
videolist = re.findall(videore,html)

Answer 1

import re
s= """var BASE_DATA = {
    headerInfo: {
      id: 0,
      isPgc: false,
      userName: '',
      avatarUrl: '',
      isHomePage: false,
      chineseTag: '视频',
      crumbTag: 'video',
      hasBar: true
    },
    playerInfo: {
      videoId: 'v03004450000bhns5g3jvcldgj685gr0'
    },"""
reg = r"videoId: '.+'"
videore = re.compile(reg)
videolist = re.findall(videore,s)
print(videolist[0][10:-2])

Answer 2

这种要用正则匹配了吧。

json.loads(re.findall('var cities = (.+);\n', response.body.decode('utf-8'))[0])

记得处理异常。
