我有一个网站，我与BeautifulSoup上提取下表
这是URL（我还附上一张照片

I have the following table on a website which I am extracting with BeautifulSoup This is the url (I have also attached a picture

我非常希望让每个公司在一排CSV但是我得到它在不同的行。请参阅所附的图片。

Ideally I would like to have each company in one row in csv however I am getting it in different rows. Please see picture attached.

我想它有它就像在现场D但我得到它在A1，A2，A3 ......

I would like it to have it like in field "D" but I am getting it in A1,A2,A3...

这是code我使用提取：

This is the code I am using to extract:

def _writeInCSV(text):
    print "Writing in CSV File"
    with open('sara.csv', 'wb') as csvfile:
        #spamwriter = csv.writer(csvfile, delimiter='\t',quotechar='\n', quoting=csv.QUOTE_MINIMAL)
        spamwriter = csv.writer(csvfile, delimiter='\t',quotechar="\n")

        for item in text:
            spamwriter.writerow([item])

read_list=[]
initial_list=[]


url="http://www.nse.com.ng/Issuers-section/corporate-disclosures/corporate-actions/closure-of-register"
r=requests.get(url)
soup = BeautifulSoup(r._content, "html.parser")

#gdata_even=soup.find_all("td", {"class":"ms-rteTableEvenRow-3"})

gdata_even=soup.find_all("td", {"class":"ms-rteTable-default"})




for item in gdata_even:
    print item.text.encode("utf-8")
    initial_list.append(item.text.encode("utf-8"))
    print ""

_writeInCSV(initial_list)

有人能帮助吗？

推荐答案

下面的理念是：

• 从表中读取头细胞


• 从表中读取所有其他行


• 压缩所有数据行细胞产生词典列表标题


• 使用 csv.DictWriter（） 转储到CSV

实施

import csv
from pprint import pprint

from bs4 import BeautifulSoup
import requests

url = "http://www.nse.com.ng/Issuers-section/corporate-disclosures/corporate-actions/closure-of-register"
soup = BeautifulSoup(requests.get(url).content, "html.parser")

rows = soup.select("table.ms-rteTable-default tr")
headers = [header.get_text(strip=True).encode("utf-8") for header in rows[0].find_all("td")]

data = [dict(zip(headers, [cell.get_text(strip=True).encode("utf-8") for cell in row.find_all("td")]))
        for row in rows[1:]]

# see what the data looks like at this point
pprint(data)

with open('sara.csv', 'wb') as csvfile:
    spamwriter = csv.DictWriter(csvfile, headers, delimiter='\t', quotechar="\n")

    for row in data:
        spamwriter.writerow(row)
