Question

我在Python中编写了一个非常简单的骰子滚动脚本。它会让你滚三次。但是，我不知道如何打破while循环并在最后一次避免raw_input。

#!/usr/bin/python

from random import randrange, uniform

def rollDice():
  dice = randrange(3,18)
  print ("You rolled: %s" % dice)

maxReRoll = 2
c = 0
reRoll = "y"

while reRoll in ["Yes", "yes", "y", "Y"]:
  if c > maxReRoll:
    break
  else:
    rollDice()
    c+=1
    reRoll = raw_input("Roll again?  y/n ")

Answer 1

只需要一点点交换。

while reRoll in ["Yes", "yes", "y", "Y"]:
  rollDice()
  c+=1
  if c >= maxReRoll:  # notice the '>=' operator here
    break
  else:
    reRoll = raw_input("Roll again?  y/n ")

Answer 2

这应该适合你：

from random import randrange


def roll_dice():
    dice = randrange(3,18)
    print("You rolled: %s" % dice)

max_rolls = 2
c = 0
re_roll = "y"

while re_roll.lower() in ["yes", "y"] and (c < max_rolls):
    roll_dice()
    c += 1
    if c != max_rolls:
        re_roll = input("Roll again?  y/n ")

在while循环中从raw_input中断
