dbapi2abc 1.1.3

Provide an Abstract Base Class for PEP249 compliant databases

dbapi2abc

This package provides abstract classes to present an interface to PEP249 compliant database Connection and Cursor objects.

This allows you to use type hints on functions handling database connections and cursors without needing to specify the specific backend database engine being used.

from dbapi2abc import Connection, Cursor

class MyObject():
    def __init__(self, db: Connection):
        self.db = db

    def run_some_query(self) -> Cursor:
        cur = self.db.cursor()
        cur.execute("SELECT * FROM Table")
        return cur
