试图用美丽的汤刮擦瑞典议员。运行刮板时,出现“ ValueError:太多值无法解包(预期3)”。

该脚本输出一个csv,但只有五个名称。列表中的第六个人名为Janm(Aline Ericson,MP)。我想问题是她有两个姓氏-Alm Ericson,并且代码只需要三个值,名字,姓氏和聚会。

我应该如何编码字段分隔符以使其也适用于双重姓氏?

页面上的名称写为

Last_name, first_name (party)


码:

import urllib.request
import bs4 as bs
import csv

source = urllib.request.urlopen("https://www.riksdagen.se/sv/ledamoter-partier/").read()
soup = bs.BeautifulSoup(source, "lxml")

data = []

for span in soup.find_all("span", {"class": "fellow-name"}):
    cleanednames = span.text.strip()
    data.append(cleanednames)  #fields are appended to list rather printing

with open("riksdagsledamoter.csv", "w") as stream:
    fieldnames = ["Last_Name","First_Name","Party"]
    var = csv.DictWriter(stream, fieldnames=fieldnames)
    var.writeheader()
    for item in data:
        last_name, First_name, party = item.split()  #splitting data in 3 fields
        last_name = last_name.replace(",","")  #removing ',' from last name
        party = party.replace("(","").replace(")","")  #removing "()" from party
        var.writerow({"Last_Name": last_name,"First_Name": First_name, "Party": party})  #writing to csv row

最佳答案

这是一个应该解决的简单正则表达式

 import re
 print(re.match("(.*), (.*) \((.*)\)", 'Alm Ericson, Janine (MP)').groups())
