提问by kingcope
I am trying to create a table scrape with BeautifulSoup. I wrote this Python code:
我正在尝试使用 BeautifulSoup 创建一个表刮。我写了这个 Python 代码：
import urllib2
from bs4 import BeautifulSoup
url = "http://dofollow.netsons.org/table1.htm" # change to whatever your url is
page = urllib2.urlopen(url).read()
soup = BeautifulSoup(page)
for i in soup.find_all('form'):
print i.attrs['class']
I need to scrape Nome, Cognome, Email.
我需要抓取 Nome、Cognome、Email。

Loop over table rows (trtag) and get the text of cells (tdtag) inside:
遍历表格行（tr标签）并获取其中的单元格文本（td标签）：
for tr in soup.find_all('tr')[2:]:
tds = tr.find_all('td')
print "Nome: %s, Cognome: %s, Email: %s" % \
(tds[0].text, tds[1].text, tds[2].text)
prints:
印刷：
Nome: ?Massimo, Cognome: ?Allegri, Email: [email protected]
Nome: ?Alessandra, Cognome: ?Anastasia, Email: [email protected]
...
FYI, [2:]slice here is to skip two header rows.
仅供参考，[2:]这里的切片是跳过两个标题行。
UPD, here's how you can save results into txt file:
UPD，这是将结果保存到txt文件的方法：
with open('output.txt', 'w') as f:
for tr in soup.find_all('tr')[2:]:
tds = tr.find_all('td')
f.write("Nome: %s, Cognome: %s, Email: %s\n" % \
(tds[0].text, tds[1].text, tds[2].text))

# Libray
from bs4 import BeautifulSoup
# Empty List
tabs = []
# File handling
with open('/home/rakesh/showHW/content.html', 'r') as fp:
html_content = fp.read()
table_doc = BeautifulSoup(html_content, 'html.parser')
# parsing html content
for tr in table_doc.table.find_all('tr'):
tabs.append({
'Nome': tr.find_all('td')[0].string,
'Cogname': tr.find_all('td')[1].string,
'Email': tr.find_all('td')[2].string
})
print(tabs)
