looking for a more pythonic way to access the database

Question

I have a bunch of python methods that follow this pattern:

def delete_session(guid):
    conn = get_conn()
    cur = conn.cursor()

    cur.execute(\"delete          


        

Answer 1

"I have a bunch of python methods that follow this pattern:"

This is confusing.

Either you have a bunch of functions, or you have a bunch of methods of a class.

Bunch of Functions.

Do this instead.

class SQLFunction( object ):
    def __init__( self, connection ):
        self.connection = connection
    def __call__( self, args=None ):
        self.cursor= self.connection.cursor()
        self.run( args )
        self.cursor.commit()
        self.cursor.close()

class DeleteSession( SQLFunction ):
    def run( self, args ):
        self.cursor.execute( "statement" )

delete_session = DeleteSession( connection )

Your function declarations are two lines longer, but essentially the same. You can do func1( args ) because it's a callable object. The rest of your program should remain unchanged.

Bunch of Methods in One Class.

class SomeClass( object ):
    def __init__( self, connection ):
        self.connection= connection
    def sql_execute( self, statement, args= None )
        self.cursor= self.connection.cursor() 
        self.cursor.execute( statement, args if args is not None else [] )
        self.connection.commit()
        self.cursor.close()
    def delete_session( self ):
        self.sql_execute( "statement" )

All your methods can look like delete_session and make use of a common sql_execute method.
