Just a minor note, this break is redundant. Breaks are used to exit (for/while)
loops but keep control in the function. A return exits the function
immediately.
if choice.lower() in ('p', 'r','s'): # Converts the user's choice to
lowercase and confirms the choice is valid
return choice
break
There is also a "continue" which is similar to a break, but instead of exiting
the loop, it will start the loop code over for the next value (thus
"continuing" the loop).
>>> t = [ 'not this', 'do this', 'not this either', 'most definitely do this' ]
>>> for string in t:
... if string.startswith( 'not' ):
... continue # I want to keep working with the other elements in the
list
... print string
...
do this
most definitely do this
>>> for string in t:
... if string.startswith( 'not' ):
... break # I want to abort the entire loop now
... print string
...
>>>
