MySQL Question

looking for a more pythonic way to access the database

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)


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:

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 ...
