I have a bunch of python methods that follow this pattern:
def delete_session(guid):
conn = get_conn()
cur = conn.cursor()
cur.execute("delete from sessions where guid=%s", guid)
conn.commit()
conn.close()
Is there a more pythonic way to execute raw sql. The 2 lines at the beginning and end of every method are starting to bother me.
I'm not looking for an orm, I want to stick with raw sql.
You could write a context manager and use the with statement. For example, see this blog post:
http://jessenoller.com/2009/02/03/get-with-the-program-as-contextmanager-completely-different/
Also the python documentation has a sample that pretty much matches your needs. See section 8.1 on this page, in particular the snippet that begins:
db_connection = DatabaseConnection()
with db_connection as cursor:
cursor.execute('insert into ...')
cursor.execute('delete from ...')
# ... more operations ...
