BeautifulSoup如何整理数据并写入txt？

Question

对于Python来说，有一个简单的问题。我正在将一些数据从Yahoo Fantasy Baseball拉入文本文件，但我的代码无法正常工作：

from bs4 import BeautifulSoup
import urllib2

teams = ("http://baseball.fantasysports.yahoo.com/b1/2282/players?status=A&pos=B&cut_type=33&stat1=S_S_2015&myteam=0&sort=AR&sdir=1")
page = urllib2.urlopen(teams)
soup = BeautifulSoup(page, "html.parser")

players = soup.findAll('div', {'class':'ysf-player-name Nowrap Grid-u Relative Lh-xs Ta-start'})

playersLines = [span.get_text('\t',strip=True) for span in players]

with open('output.txt', 'w') as f:
    for line in playersLines:
        line = playersLines[0]
        output = line.encode('utf-8')
        f.write(output)

在输出文件中只有一个播放器25次。有什么办法得到这样的结果吗？你知道吗

Pedro Álvarez   Pit - 1B,3B
Kevin Pillar    Tor - OF
Melky Cabrera   CWS - OF
etc

Answer 1

尝试删除： line = playersLines[0]

另外，在输出的末尾添加一个换行符字符，以使它们写入输出.txt文件：

from bs4 import BeautifulSoup
import urllib2

teams = ("http://baseball.fantasysports.yahoo.com/b1/2282/players?status=A&pos=B&cut_type=33&stat1=S_S_2015&myteam=0&sort=AR&sdir=1")
page = urllib2.urlopen(teams)
soup = BeautifulSoup(page, "html.parser")

players = soup.findAll('div', {'class':'ysf-player-name Nowrap Grid-u Relative Lh-xs Ta-start'})

playersLines = [span.get_text('\t',strip=True) for span in players]

with open('output.txt', 'w') as f:
    for line in playersLines:
        output = line.encode('utf-8')
        f.write(output+'\n')

结果：

Pedro Álvarez   Pit - 1B,3B
Kevin Pillar    Tor - OF
Melky Cabrera   CWS - OF
Ryan Howard     Phi - 1B
Michael A. Taylor       Was - OF
