csv - python多列存取爬蟲網頁？

问题描述

问 题

爬虫抓取的资料想分列存取在tsv上,试过很多方式都没有办法成功存存取成两列资讯。
想存取为数字爬取的资料一列,底下类型在第二列

from urllib.request import urlopen
from bs4 import BeautifulSoup
import re
import csv

html = urlopen("http://www.app12345.com/?area=tw&store=Apple%20Store")
bs0bj = BeautifulSoup (html)


def GPname():
    GPnameList = bs0bj.find_all("dd",{"class":re.compile("ddappname")})
    str = ''
    for name in GPnameList:
        str += name.get_text()
        str += '\n'
        print(name.get_text())

    return str


def GPcompany():

    GPcompanyname = bs0bj.find_all("dd",{"style":re.compile("color")})
    str = ''
    for cpa in GPcompanyname:
        str += cpa.get_text()
        str += '\n'
        print(cpa.get_text())
    return str




with open('0217.tsv','w',newline='',encoding='utf-8') as f:
    f.write(GPname())
    f.write(GPcompany())

f.close()

可能对zip不熟悉，存取下来之后变成一个字一格
也找到这篇参考，但怎么尝试都没有办法成功

解决方案

写csv文件简单点 你的结构数据要成这样 [["1. 東森新聞雲","新聞"],["2. 創世黎明(Dawn of world)","遊戲"]]

from urllib import urlopen
from bs4 import BeautifulSoup
import re
import csv

html = urlopen("http://www.app12345.com/?area=tw&store=Apple%20Store")
bs0bj = BeautifulSoup (html)
GPnameList = [name.get_text() for name in bs0bj.find_all("dd",{"class":re.compile("ddappname")})]
GPcompanyname = [cpa.get_text() for cpa in bs0bj.find_all("dd",{"style":re.compile("color")})]

data = '\n'.join([','.join(d) for d in zip(GPnameList, GPcompanyname)])
with open('C:/Users/sa/Desktop/0217.csv','wb') as f:
     f.write(data.encode('utf-8'))
