获取单独一个table，代码如下：

									# _*_ coding=utf-8 _*_

									import csv

									from urllib.request import urlopen

									from bs4 import BeautifulSoup

									from urllib.request import HTTPError

									try:

									  html = urlopen("http://en.wikipedia.org/wiki/Comparison_of_text_editors")

									except HTTPError as e:

									  print("not found")

									bsObj = BeautifulSoup(html,"html.parser")

									table = bsObj.findAll("table",{"class":"wikitable"})[0]

									if table is None:

									  print("no table");

									  exit(1)

									rows = table.findAll("tr")

									csvFile = open("editors.csv",'wt',newline='',encoding='utf-8')

									writer = csv.writer(csvFile)

									try:

									  for row in rows:

									    csvRow = []

									    for cell in row.findAll(['td','th']):

									      csvRow.append(cell.get_text())

									    writer.writerow(csvRow)

									finally:

									  csvFile.close()

获取所有table，代码如下：

				?

									#!/usr/bin/env python3

									# _*_ coding=utf-8 _*_

									import csv

									from urllib.request import urlopen

									from bs4 import BeautifulSoup

									from urllib.request import HTTPError

									try:

									  html = urlopen("http://en.wikipedia.org/wiki/Comparison_of_text_editors")

									except HTTPError as e:

									  print("not found")

									bsObj = BeautifulSoup(html,"html.parser")

									tables = bsObj.findAll("table",{"class":"wikitable"})

									if tables is None:

									  print("no table");

									  exit(1)

									i = 1

									for table in tables:

									  fileName = "table%s.csv" % i

									  rows = table.findAll("tr")

									  csvFile = open(fileName,'wt',newline='',encoding='utf-8')

									  writer = csv.writer(csvFile)

									  try:

									    for row in rows:

									      csvRow = []

									      for cell in row.findAll(['td','th']):

									        csvRow.append(cell.get_text())

									      writer.writerow(csvRow)

									  finally:

									    csvFile.close()

									  i += 1
