Cannot make connection to accdb file using python

Question

I am writing a script that needs to make a connection to a microsoft access .accdb file and extract data from it.

Here is a snippet of what I am doing?

import pypyodbc
pypyodbc.lowercase = False

conn = pypyodbc.connect(
       r'DRIVER={Microsoft Access Driver (*.mdb, *.accdb)};' +
       r'DBQ=file.accdb;'
       )
cur = conn.cursor()

I get the following error:

    raise Error(state,err_text)
pypyodbc.Error: ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified')

I have installed the drivers for ODBC as instructed in https://docs.microsoft.com/en-us/sql/connect/python/pyodbc/step-1-configure-development-environment-for-pyodbc-python-development

But the error persists, any idea what should I do or where I am going wrong?
