Question

我正在制作一个程序来随机制造一个对事物具有影响力的神，并影响与原始事物相关的事物。相关部分是：

spheres = {'death': ['death', 'corpses', 'skulls', 'rot', 'ruin', 'the end']}
# Dictionary of the things gods have power over and the relevant things to do with them

class God(object):

  def __init__(self, sphere, associations, name):
    self.sphere = sphere
    self.associations = accociations
    self.name = name
# Chooses areas to have power over, hopefully making it less and less likely as the program goes on further      
  def get_association(self):
    chance_of_association = 0
    list_of_choices = []
    while random.randint(0, chance_of_association) == 0:
      choice = random.choice(list(spheres[self.sphere]))
      # this is the problem
      if random.randint(1, 2) == 1:
        chance_of_association += 1
      list_of_choices.append(choice)
    self.associations = list_of_choices

deity1 = God(random.choice(spheres), deity1.get_association, 'godname')

当我跑步时，我得到：

  File "program.py", line 22, in <module>
    deity1 = God(random.choice(spheres), deity1.get_association, 'godname')
  File "/opt/python-3.6/lib/python3.6/random.py", line 258, in choice
    return seq[i]
KeyError: 0

即使行中没有list（），它也会产生相同的错误。我怎么能得到它

Answer 1

您可以将行更改为

deity1 = God(random.choice(spheres['death']), deity1.get_association, 'godname')

但是这也会产生另一个错误，所以请再次查看您的代码。

Traceback (most recent call last):
File "<input>", line 23, in <module>
NameError: name 'deity1' is not defined

Answer 2

import random

spheres = {'death': ['death', 'corpses', 'skulls', 'rot', 'ruin', 'the end']}
# Dictionary of the things gods have power over and the relevant things to do with them

class God(object):

  def __init__(self, sphere, name, associations = None):
    self.sphere = sphere
    #so associations are not allocated twice
    self.possible_associations = spheres[self.sphere] 
    self.associations = associations
    self.get_association()
    self.name = name
# Chooses areas to have power over, hopefully making it 
# less and less likely as the program goes on further      
  def get_association(self):
    chance_of_association = 0
    list_of_choices = []
    while random.randint(0, chance_of_association) == 0 and self.possible_associations:
      choice = random.choice(self.possible_associations)
      self.possible_associations.remove(choice)
      if random.randint(1, 2) == 1:
        chance_of_association += 1
      list_of_choices.append(choice)
    self.associations = list_of_choices

由于尚未创建对象，因此在实例化过程中无法引用“diety1＆＃39;”并调用它的方法＆＃39; get_association＆＃39;因此，我们将方法调用移至__init__运行时。我们不得不改变random.choice来搜索字典中的键列表。

deity1 = God(random.choice(list(spheres.keys())), 'godname')

从列表中的字典值中选择random.choice时不起作用
