trying create web application (using mysql , python) list of hiking trails in ma. want display names of trails in db on 1 page , cannot figure out why nothing display:

################################################################################ def getallhikes(): """ middleware function read database. returns list containing records of trails have in table. """  # connect db conn, cursor = getconnectionandcursor()  # prepare sql sql = """ select name hiking """  # run sql cursor.execute(sql)  # fetch results data = cursor.fetchall()  # clean cursor.close() conn.close()  return data  ################################################################################ def showallhikes(data): '''produce table showing trails, 1 per row.'''  print(''' here popular trails have on file: <table>     <tr>       <td>%s</td>       <td>%s</td>       <td>%s</td>       <td>%s</td>       <td>%s</td>     </tr>       ''') % (name, town)  print(''' </table> ''') ################################################################################ if __name__ == "__main__":  # form field data form = cgi.fieldstorage()  dohtmlhead("masshike: database of popular massachusetts trails")  data = getallhikes() showallhikes(data)   dohtmltail() 

i encounter problem when try work web applications. error saying args = ("global name 'name' not defined",)

if can explain in simple terms appreciate it. don't understand @ all. thanks!

the issue within method below. not have name or town defined within function or @ global level.

def showallhikes(data):     '''produce table showing trails, 1 per row.'''      print('''     here popular trails have on file:     <table>         <tr>           <td>%s</td>           <td>%s</td>           <td>%s</td>           <td>%s</td>           <td>%s</td>         </tr>           ''') % (name, town)      print('''     </table>     ''') 

in order information need go through data according mysql fetchall appears list of tuple.

with information can following:

print('''     here popular trails have on file:     <table>''') name, town in data:     print('''         <tr>           <td>%s</td>           <td>%s</td>         </tr>           ''') % (name, town)  print('''     </table>     ''') 

however, looks sql query needs include town information sql = """select name hiking""", more fail with:

traceback (most recent call last):   file "<console>", line 1, in <module> valueerror: need more 1 value unpack
