how to deal with .mdb access files with python

This looks similar to a previous question:

• What do I need to read Microsoft Access databases using Python?
• http://code.activestate.com/recipes/528868-extraction-and-manipulation-class-for-microsoft-ac/

Answer there should be useful.

For a solution that works on any platform that can run Java, consider using Jython or JayDeBeApi along with the UCanAccess JDBC driver. For details, see the related question

Read an Access database in Python on non-Windows platform (Linux or Mac)

There's the meza library by Reuben Cummings which can read Microsoft Access databases through mdbtools.

Installation

# The mdbtools package for Python deals with MongoDB, not MS Access. 
# So install the package through `apt` if you're on Debian/Ubuntu
$ sudo apt install mdbtools
$ pip install meza

Usage

>>> from meza import io

>>> records = io.read('database.mdb') # only file path, no file objects
>>> print(next(records))

Table1
Table2

Below is some code I wrote for another SO question.
It requires the 3rd-party pyodbc module.

This very simple example will connect to a table and export the results to a file.
Feel free to expand upon your question with any more specific needs you might have.

import csv, pyodbc

# set up some constants
MDB = 'c:/path/to/my.mdb'
DRV = '{Microsoft Access Driver (*.mdb)}'
PWD = 'pw'

# connect to db
con = pyodbc.connect('DRIVER={};DBQ={};PWD={}'.format(DRV,MDB,PWD))
cur = con.cursor()

# run a query and get the results 
SQL = 'SELECT * FROM mytable;' # your query goes here
rows = cur.execute(SQL).fetchall()
cur.close()
con.close()

# you could change the mode from 'w' to 'a' (append) for any subsequent queries
with open('mytable.csv', 'w') as fou:
    csv_writer = csv.writer(fou) # default field-delimiter is ","
    csv_writer.writerows(rows)
