[SOLVED]Python3 Differing output between machines

I am a TA at my University and I have been grading projects the past few days and I've run into a weird issue with python in that it replaces numbers the letters 'b' and 'm'. For example running the students code I should be ending up with something that looks like a guitar tab

example expected output

e | ---3------------
B | ---------4------
G | ---------------7
D | ------------1---
A | ------2--------
E | 1--------------

but instead I end up with

e | ---b------------
B | ---------m------
G | ---------------b
D | ------------b---
A | ------m--------
E | b--------------

It happens on all the student code and on my other machines it works fine and as expected. I can't (due to privacy issues) post any student code but if it helps I can roughly walk you through it if need be. I am wondering why this would be happening though.

Not much to go on.  Are the locales set properly?  Is something changing the character encoding?
Is the code depending upon a dictionary?  Does the code make assumptions about the order of entries in a dictionary?
Why not use pdb and breakpoint the code at the instruction that is printing the offending character and take a look at the data structures?

I'm more concerned with the size and shape of these guitar players' hands.

Following the ewaller's ideas:
  Could be how the editor encode the file?
  Could be trying to run Python 2?
    # -*- coding: utf-8 -*-

It is curious that odd numbers are 'b' and the even 'm'.

I can't (due to privacy issues) post any student code...

Can you replicate any part of the problem with your own similar code that you could share?

Or can you at least give the single line of code that actually prints the output?  Are format strings used?  If so, which one of the many variations?  Is a dict of variables and/or the local variables interpolated into a format string?
