Cameron is wrong (he's probably coming from the C side of things). 
You can invoke sys.exit() with arbitrary objects:

"""
Help on built-in function exit in module sys:

exit(...)
    exit([status])
    
    Exit the interpreter by raising SystemExit(status).
    If the status is omitted or None, it defaults to zero (i.e., success).
    If the status is an integer, it will be used as the system exit status.
    If it is another kind of object, it will be printed and the system
    exit status will be one (i.e., failure).
"""

> How to I display error messages with sys.exit then ?

Wrong question; if you want to use sys.exit() in a way similar to C display 
the error message first and invoke sys.exit() afterwards with a numerical 
argument.
