How to generate addresses from a file rather than specific phase

0 votes

I am using the following python script to generate bitcoin wallet address, however I am having to enter each phrase into the code and generate one at a time, how would I adjust the code to generate bitcoin addresses from a list.txt file held in the same directory. 

This is my code:

#!/usr/bin/env python

If the file with the passwords is password.txt (you have to save one password per line) you can do:

#fileName = string
def parseFile(filename):
    with open(filename, 'r') as passwords:
        for password in passwords:
            var adds = newAddress(password); # you have to define newAddress
