My python program works fine in Windows 7 and prints to the console but gives an error in Linux Mint?

Question

I am coding a program in windows. I started up my linux mint hardrive and for some reason it gives an error in the mint but not windows 7? Here are the 3 files of the program:

main.py:

#-------------------------------------------------------------------------------
# Name:        main.py
# Purpose:     An RPG (Roll playing game) where you wake up in a room and have
#              to figure out text based puzzles to escape.
#              The whole game will be done in a terminal (Shell) and will be
#              completely text and ascii code. This will be the main file.

After the function ascii.ywu_banner(2) I use in main.py I get this error:

Press ENTER/RETURN on your keyboard to start the game
Traceback (most recent call last):
  File "main.py", line 102, in <module>

Answer 1

You did not specify which Python version(s) you were using, but I assume you have 3.x on Windows and 2.x on Linux. input() doen't work the same on Python 2.x and Python 3.x. On 2.x it tries to eval the user's input as Python code (which is very unsafe fwiw), which would explain your error if trying to run 3.x code on 2.x.

NB : the 2.x equivalent of 3.x input() is named raw_input() but you migh have a few other incompatibilites anyway.
