The pyodbc module in Python offers a powerful and flexible way to interact with databases using the Open Database Connectivity (ODBC) standard. cnxn = pyodbc. connect has something similar. connect string to a format sqlalchemy can then pass through correctly to pyodbc. In data source connections between a client and server there are two general types: ODBC which uses a DRIVER and OLEDB which uses a PROVIDER. py downloaded from this repository on your project folder and import the module. pyodbc is a Python library that enables Python programs to interact with databases through ODBC (Open Database Connectivity), a standard API for accessing database management systems (DBMS). If you want to use 64bit access files you should use 64 bit MS Acceess which provides driver.
