[mdlug] Python Code Question

[Gregory Czerniak]

Two things:
1) You can python3-ize the above code by treating print as a function (wrap
the thing to be printed in parentheses) and using input() rather than
raw_input().
2) Interactive mode only executes one command at a time.  The "while"
statement (and all its indented statements) are one command, and print
'Bye' is another.  The interactive Python interpreter is getting confused
by that final print statement since it's not on the same indent level as
the other statements in the "while" and it's assuming everything is still
related to the "while."
