我用beauthulsoup来编写HTML代码。在代码中，我要创建的变量是存在的，不存在。在某些参数发生变化时，我必须更改值，将present更改为absent，反之亦然。 我要把pesent/leave设为变量'a'。在

你的意思是用beauthoulsoup从python数据的某个表单构造自己的html吗？如果是这样，下面的示例可能对您有用：

from bs4 import BeautifulSoup, Tag
import os

subjects = ['subject1', 'subject2']
vals = [['absent','present'],['absent','absent']] #rows

titles = ['Roll No.'] + subjects

html = """<html>
              <body>
                  <table class="details" border="1" cellpadding="5" cellspacing="2" style="width:95%">
                  </table>
              </body>
          </html>"""
soup = BeautifulSoup(html)

#find table tag
table = soup.find('table')

#add header to table tag
tr = Tag(table, name = 'tr')
for title in titles:
    td = Tag(tr, name = 'td')
    td.insert(0, title)
    tr.append(td)
table.append(tr)

#add data to table one row at a time
for i in range(len(vals[0])):

    tr = Tag(table, name = 'tr')

    td = Tag(tr, name = 'td')
    td.string = str(i+1)
    tr.append(td)

    for val in vals[i]:
        td = Tag(tr, name = 'td')
        td.string = val
        tr.append(td)

    table.append(tr)

os.chdir(os.getcwd())
f = open('test.html','w')
f.write(soup.prettify())
f.close()
