Fobj = open(“my.html”);
Data = fobj.read();
Fobj.close();

Soup = BeautifulSoup(data);
Trlist = soup.findAll(“tr”);
Rownum = len(trlist);
Colnum = len(trlist[0]);
Trlist[0].insert(colnum, “<td>hahaha</td>”);
Tdlist = trlist[0].findAll(“td”);
Content= tdlist[0].renderContents();
Fobj = file(“my.html”, “w”);
Fobj.write(str(soup));
Fobj.close();
