获取单独一个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") 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
