python - 滚动两个骰子: SyntaxError: 'return' outside function?

Question

我正在尝试实现一个将两个骰子作为输入并计算两个值的函数。

第一个值是第一个骰子获胜的次数(在所有可能的36个选择中)，第二个值是第二个骰子获胜的次数。

这是我的代码:

def count_wins(dice1, dice2):
  assert len(dice1) == 6 and len(dice2) == 6
  dice1_wins, dice2_wins = 0, 0

# write your code here
dice1 = input('1, 2, 3, 4, 5, 6')
dice2 = input('1, 2, 3, 4, 5, 6')
def roll_dice():
  return(random.randint(1, 2, 3, 4, 5, 6),random.randint(1, 2, 3, 4, 5, 6))
for i in range(36):
  dice1, dice2 = roll_dice()
  if dice1 > dice2:
    dice1_wins+=1
  if dice2 > dice1:
    dice2_wins+=1
  if dice2 == dice1:
    pass
return (dice1_wins, dice2_wins)

但这给了我这个错误:

Error on line 17:
    return (dice1_wins, dice2_wins)
    ^
SyntaxError: 'return' outside function

我试图为您修复缩进，请尝试以下代码:

import random

def count_wins():
    dice1_wins, dice2_wins = 0, 0
    for i in range(0,36):
      dice1, dice2 = roll_dice()
      if dice1 > dice2:
        dice1_wins+=1
      if dice2 > dice1:
        dice2_wins+=1
      if dice2 == dice1:
        pass
    return (dice1_wins, dice2_wins)


def roll_dice():
  return(random.randint(1,6),random.randint(1,6))#returns random numbers between 1 to 6.

print (count_wins())#Calls the method count_wins and prints the required output.
