python3 beautifulsoup 表格指定行_BeautifulSoup按数字指定表格列？

Using Python 2.7 and BeautifulSoup 4, I'm scraping song names from a table.

Right now the script finds links in the row of a table; how can I specify I want the first column?

Ideally I'd be able to switch numbers around to change which ones got selected.

Right now the code looks like this:

from bs4 import BeautifulSoup

import requests

r = requests.get("http://evamsharma.finosus.com/beatles/index.html")

data = r.text

soup = BeautifulSoup(data)

for table in soup.find_all('table'):

for row in soup.find_all('tr'):

for link in soup.find_all('a'):

print(link.contents)

How do I, in effect, index the

The URL in there right now is a page on my site where I basically copied the table source from Wikipedia to make the scraping a little simpler.

Thanks!

Find all td tags inside tr and get the one you need by index:

index = 2

for table in soup.find_all('table'):

for row in soup.find_all('tr'):

try:

td = row.find_all('td')[index]

except IndexError:

continue

for link in td.find_all('a'):

print(link.contents)
