How to break out of while loop in Python?

A couple of changes mean that only an R or r will roll. Any other character will quit

import randomwhile 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

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

ans=(R)while True:    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    else:        print("Now I'll see if I can break your score...")        ans = False        break
