code review

[Aniq99]

well commented code. Easy to read thanks to the whitespace. I like the addition of the Player class to make it provide a more tailored experience.
here is a slight issue in the player class that allows for negative ages to be inputted. Probably best to handle these cases. Also, could just use two while loops instead of three when creating the pack. That way, the code will be more efficient (allows you to just add a simple if statement to check if the pack size is correct).
Overall really well done
