What I would do is run the loop until the ans is Q  ans  R  while not ans   Q       print  Your score is so far   str myScore           print  Would you like to roll or quit        ans input  Roll          if ans   R           R random randint 1  8          print  You rolled a   str R               myScore R myScore

A couple of changes mean that only an R or r will roll  Any other character will quit  import random  while True      print  Your score so far is      format myScore       print  Would you like to roll or quit        ans   input  Roll          if ans lower       r           R   np random randint 1  8          print  You rolled a      format R           myScore   R   myScore     else          print  Now I ll see if I can break your score              break

Don t use while True and break statements  It s bad programming   Imagine you come to debug someone else s code and you see a while True on line 1 and then have to trawl your way through another 200 lines of code with 15 break statements in it  having to read umpteen lines of code for each one to work out what actually causes it to get to the break  You d want to kill them   a lot   The condition that causes a while loop to stop iterating should always be clear from the while loop line of code itself without having to look elsewhere   Phil has the  correct  solution  as it has a clear end condition right there in the while loop statement itself

Walrus operator  assignment expressions added to python 3 8  and while-loop-else-clause can do it more pythonic  myScore   0 while ans    input  quot Roll    quot   lower       quot r quot             do something else      print  quot Now I ll see if I can break your score    quot
