Question

Write a function redact() takes as input a file name. See secret.txt for the initial test. The function should print the contents of the file on the screen with this modification: Every occurrence of string 'secret' in the file should be replaced with string 'xxxxxx'. Every occurrence of “agent’ should be replaced with ‘yyyyyy’. Every occurrence of carrier should be replaced with ‘zzzzzz’. This function should catch exceptions.

                line = line.strip()
                for word in line.split():
                    word_c = word.lower()
                    if 'secret' in word_c:
                        word = word_c.replace('secret','xxxxxx')
                    elif 'agent' in word_c:
                        word = word_c.replace('agent', 'yyyyyy')
                    elif 'carrier' in word_c:
                        word = word_c.replace('carrier', 'zzzzzz')
                    print(word, end=' ')
                print()
    except:
        print('Error: File {} not found'.format(filename))


redact('secrets.txt')
