For reason unknown to me the script dont repeat itself
when asked if to play again or not no matter what juggling of the
while/if conditionals i do, the result is the same. What am i
missing?

Also, I'm not sure I'm right in the assignment ans = choose_Cave.
I code it like so because the assignment ans = choose_Cave()
the prompt 'Choose a cave' is repeated when the script is run.
Dont want this. I tested this when run in ipython.

I dont know if there is a way to just retrieve the return value to a
variable AND not run the whole function i mean in the case of
ans = choose_Cave(). Would love to hear your expert insights by return.
