Python provides the shelve module for just this sort of thing: import shelve class Contact: def __init__(self, name): self.name = name self.address = "" self.phone = "" with shelve.open("contacts") as db: dave = Contact("Dave Smith") dave.address = "123 Main St\nAnytown, NY 12345" dave.phone = "800-555-1212" db["dave"] = dave ellen = Contact("Ellen Waite") ellen.phone = "+1234567890" db["ellen"] = ellen Then at some future point you can use with shelve.open("contacts") as db: dave = db["dave"] print(f"Dave lives at {dave.address}") ellen = db["ellen"] print(f"Ellen's phonenumber is {ellen.phonenumber}") I'll leave to you the details of implementing an actual address-book out of these parts. Be sure to read the docs for the shelve module https://docs.python.org/3/library/shelve.html including the various security warnings and caveats. -tkc -- https://mail.python.org/mailman/listinfo/python-list
