python equivalent of php implode

[Maksim Kasimov]

   in php-scripts, to insert data to database, i'm doing like this:

   ...
   $query_param = array(
     'field0' => 1,
     'field1' => 3,
     'field2' => $var2,
     'field3' => $var3,
   );
   ...

   $sql = "INSERT INTO $table (".implode(", ", array_keys($query_param)).") VALUES ('".implode("','", $query_param)."')";

   how it can be done, using python (elegantly, without cycles)?
