I get an exception if I put 'elf' in as my race selection.
Please see the following steps to reproduce this problem.

Choose a race
1- Human		2- Elf		3- Orc
My race is: elf
Traceback (most recent call last):
  File "./knight-training", line 258, in <module>
    main()
  File "./knight-training", line 227, in main
    create_hero()
  File "./knight-training", line 105, in create_heroe_choice = int(input("My race is: "))
ValueError: invalid literal for int() with base 10: 'elf'
