如何使这个变量的结果？

Question

现在它设置为写入文件，但我希望它将值输出到一个变量。不知道如何。

from BeautifulSoup import BeautifulSoup 
import sys, re, urllib2 
import codecs 


woof1 = urllib2.urlopen('someurl').read() 
woof_1 = BeautifulSoup(woof1) 
woof2 = urllib2.urlopen('someurl').read() 
woof_2 = BeautifulSoup(woof2) 

GE_DB = open('GE_DB.txt', 'a') 

for row in woof_1.findAll("tr", { "class" : "row_b" }): 
    for col in row.findAll(re.compile('td')): 
    GE_DB.write(col.string if col.string else '') 
GE_DB.write(" ") 
GE_DB.write("\n") 
GE_DB.close() 
for row in woof_2.findAll("tr", { "class" : "row_b" }): 
    for col in row.findAll(re.compile('td')): 
    GE_DB.write(col.string if col.string else '') 
GE_DB.write("\n") 
GE_DB.close() 

Answer 1

values = [] 
for row in woof_1.findAll("tr", { "class" : "row_b" }): 
    for col in row.findAll(re.compile('td')): 
    if col.string: 
     values.append(col.string) 
result = ''.join(values) 

Answer 2

也许是这样的。

gedb = ""; 
for row in woof_1.findAll("tr", { "class" : "row_b" }): 
    for col in row.findAll(re.compile('td')): 
    if col.string: 
     gedb += col.string 

Answer 3

import cStringIO as StringIO # or import StringIO if on a fringe platform 
buf = StringIO.StringIO() 
for row in woof_1.findAll("tr", { "class" : "row_b" }): 
    for col in row.findAll(re.compile('td')): 
    buf.write(col.string if col.string else '') 

result = buf.getvalue() 

Answer 4

摆脱所有提及GE_DB的。

做一个 outputtext = "" 开始。

更换GE_DB.write(col.string if col.string else '')与outputtext += col.string if col.string else ''
