Question

我试图实现一个以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：

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

但它给了我这个错误：

{{1}}

我尝试为您修复缩进，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.

from random import  randint


dice1 = [1, 1, 6, 6, 8, 8]

dice2 = [2, 2, 4, 4, 9, 9]


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(randint(1,6),randint(1,6))#returns random numbers between 1 to 6.
print (count_wins())
