A Little Puzzle

Open a file specified by the user. This file will contain a bunch of characters. You should read in each character from the file, one character at a time. Display every third character on the screen. Throw the other characters away.

There is a sample input file called puzzle.txt, containing a little message you can use to test your program.

For fun, the “thrown-away” characters might say something, too, in case you care to try to view them somehow.

Name your program puzzle.py

• puzzle.txt

• puzzle2.txt

Open which file: puzzle2.txt

# The secret message should appear here...

Each file contains three messages. Can you display all three but use only one loop?
