Question

我是一名业余15岁的程序员，他对Python中的功能相对较新，从未使用过OOP Python，但是我已经深入研究了它。我们的课程项目是制作一个简单的骰子游戏，但我试图扩展我的技能。源代码将在下面，我将留下评论，我想要帮助（所以不要告诉我有一个哈希，那是让你知道我认为我出错的地方）。每当我运行程序时，控制台都会出现以下错误：

Traceback (most recent call last):
  File "python", line 5, in <module>
  File "python", line 52, in DiceGame
  File "python", line 30, in main
NameError: name 'sides' is not defined

以下是源代码：

#Jabir Hussains Source Code - Dice Task
import random

x = "Error!"

class DiceGame():
  def sides():
    sides = int(input("How many sides would you like on your di[c]e?"))
    if sides > 10:
      print("Sorry, the developer didn't have the time to program above 10 dice")
      sides = int(input("How many sides do you like on your di[c]e?"))
    elif sides < 6:
      print("The limit is 6 sides. Please try again")
      sides = int(input("How many sides do you like on your di[c]e?")) #Here I've defined the number of sides
    else:
      return sides
  sides()

  def diceNum():
    numDice = int(input("How many dice would you like?"))
    if numDice > 2:
      print("We're limited to 2 dice, please try again")
    elif numDice < 1:
      print("That is mathematically impossible. Please try again")
      numDice = int(input("How many dice would you like?"))
    else:
      return numDice
  diceNum()

  def main():
    if sides == 6 and numDice == 1:
      print("The number is",random.randint(1,6),"!")
    elif sides == 6 and numDice == 2:
      print("The numbers are",random.randint(1,6),"and",random.randint(1,6),"!")
    elif sides == 7 and numDice == 1:
      print("The number is",random.randint(1,7),"!")
    elif sides == 7 and numDice == 2:
      print("The numbers are",random.randint(1,7),"and",random.randint(1,7),"!")
    elif sides == 8 and numDice == 1:
      print("The number is",random.randint(1,8),"!")
    elif sides == 8 and numDice == 2:
      print("The numbers are",random.randint(1,8),"and",random.randint(1,8),"!")
    elif sides == 9 and numDice == 1:
      print("The number is",random.randint(1,9),"!")
    elif sides == 9 and numDice == 2:
      print("The numbers are",random.randint(1,9),"and",random.randint(1,9),"!")
    elif sides == 10 and numDice == 1:
      print("The number is",random.randint(1,10),"!")
    elif sides == 10 and numDice == 2:
      print("The numbers are",random.randint(1,10),"and",random.randint(1,10),"!")
    else:
      print(x)
  main()
DiceGame()

这里有很多错误，我不知道从哪里开始。

但主要观点是：

1）你应该从＆＃34; object＆＃34;

定义一个类

class YourClass(object):

2）你需要一个 init 方法（它有点像构造函数，看看这个）

def __init__(self, arg1, arg2):

3）为了使用类中的对象，你必须实例化它

yourObject = YourClass(arg1, arg2)

完成后，您可以这样做：

yourObject.yourFunction()

我希望这会有所帮助，但请查看文档：

https://docs.python.org/2.7/

当我声明一个时，DiceGame会返回一个错误，说没有变量？
