使用 BeautifulSoup 解析特定内容

Question

我希望从网站中提取梦幻足球信息。 我可以编写足够的代码来获得以下输出，但我真正想要的是以下信息：

"fullName":"Justin Forsett"
"pointsSEASON":75

谁能帮助解释如何隔离这些项目并将它们写入例如 csv 文件？

[<div class="mod-content" id="fantasy-content">{"averagePoints":9.4,"percentOwned":98.6,"pointsSEASON":75,"seasonOutlook":{"outlook":"Forsett finished 2014 as fantasy's No. 8 RB, so why aren't we higher on him? Well, it's difficult to reconcile what we know about his size (5-8, 197), age (30 in October) and career with the 1,529 scrimmage yards he racked up as Baltimore's surprise starter. Forsett had never even eclipsed 1,000 total yards in any of his six previous seasons. Yet his quickness and vision were consistently excellent last year, and new OC Marc Trestman loves throwing to RBs.

您要查找的标签文本似乎是 JSON 格式。您已成功获取div 标签，但现在您必须提取 JSON，然后提取您想要的信息。这是您需要添加到代码中的内容。

import json

rawJSONString = {originaltag}.get_text()
JSONString = json.loads(rawJSONString)
print(JSONString['fullName'])
print(JSONString['pointsSEASON'])

{originaltag} 是您在上面打印的标签，因为您没有显示您的代码，所以我无法运行它。相反，我运行了以下代码

string = '{"averagePoints":9.4,"percentOwned":98.6,"pointsSEASON":75,"seasonOutlook":{"outlook":"Forsett finished 2014 as fantasys No. 8 RB, so why arent we higher on him? Well, its difficult to reconcile what we know about his size (5-8, 197), age (30 in October) and career with the 1,529 scrimmage yards he racked up as Baltimores surprise starter. Forsett had never even eclipsed 1,000 total yards in any of his six previous seasons. Yet his quickness and vision were consistently excellent last year, and new OC Marc Trestman loves throwing to RBs. Lorenzo Taliaferro and rookie Javorius Allen loom as heftier options, and some kind of rotation could develop. But Forsett will get the benefit of the doubt in Week 1.","seasonId":2015,"date":"Wed May 20"},"positionRank":18,"playerId":11467,"percentChange":-0.2,"averageDraftPosition":42.5,"fullName":"Justin Forsett","mostRecentNews":{"news":null,"spin":"The Jaguars have allowed the second-fewest yards per carry (3.4) in the league, but have ceded one rushing score per game in the process. Forsett will need a good deal of volume to overcome a quietly tough matchup, but were trusting the workload will be enough.","date":"Tue Nov 10"},"totalPoints":75,"projectedPoints":13.957546548,"projectedDifference":4.582546548}'
s = json.loads(string)
print(s['fullName'])
print(s['pointsSEASON'])

得到这个输出

Justin Forsett
75
