Como eu faço o resultado disso uma variável?

Question

No momento, está configurado para gravar em um arquivo, mas eu quero que ele produz o valor para uma variável. Não tenho certeza de como.

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

Livre -se de todas as menções do GE_DB.

Faça um outputtext = ""no início.

Substituir GE_DB.write(col.string if col.string else '') com outputtext += col.string if col.string else ''

Answer 3

Talvez assim.

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 4

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()
