コード(Emacs)

#!/usr/bin/env python3
# -*- coding: utf-8 -*-


filename_in = "sample45.txt"

filename_out = input('the name of the output file: ')

with open(filename_in) as in_f, open(filename_out, 'w') as out_f:
    for line in in_f:
        line = line.replace('utilize', 'use')
        print(line, file=out_f, end='')

入出力結果(Terminal, IPython)

$ ./sample45.py
the name of the output file: sample45.out
$ cat sample45.out 
One should never use the word "use" in wrting. Use "use" instead.
