Question

我是一个python初学者，我想将我的代码包装在一个类中。但是，当我运行代码时，我得到一个AttributeError：'Generating_objects'对象没有属性'pick_type'。请告诉我哪里出错了？

import random
from random import choice

class Generating_objects(object):
      """This class would be used to generate objects of different types e.g 
          integers, string, lists and so on"""


    def __init__(self):
        pass



    def generateRandomInt(self):
        self.num = random.randint(-100000, 1000000000)
        return self.num



    def pick_type(self):

       lists = ["Int","String","Float","bool"]

       choices = choice(lists)


       if choices == "Int":
          print generateRandomInt()
       else:
          print "BOO"

genR = Generating_objects()
genR.pick_type()

Answer 1

Python是缩进敏感的。你的方法需要在类中缩进（即比类声明更多）：

class Generating_objects(object):
  """This class would be used to generate objects of different types e.g 
      integers, string, lists and so on"""

  def __init__(self):
    pass
    ...

  def pick_type(self):
    ...

代码中的缩进不正确。请查看此链接以供参考。 Python: I'm getting an 'indented block' error on the last 3 quotes (""") of my comments under functions. What's up?
