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
