Question

我是python（2.x）上的新编程，甚至找几个小时我都解决不了问题。 Python返回KeyError

（对象）.csv文件是：

id,name,type
1,low,player

python代码是：

import csv

class Item(object):

    def setup(self, config):
        self.config = config
        self.label = config['label']
        self.name = config['name']
        self.type = config['type']
def create_item(config):
    new_item = Item()
    new_item.setup(config)
    return(new_item)

def populate():
    all_items = {}
    f = open('object.csv', 'rb')
    reader = csv.DictReader(f, delimiter = ',')
    for row in reader:
        new_item = (create_item(row))
        all_items[new_item.label] = new_item 
    return(all_items)

Python返回：

Self.type = config['type']
KeyError: 'type'

奇怪的是，在csv和python代码中，列标题都不包含任何输入错误。当我更改“id”列的名称时，错误将返回到新标题（以前为“id”）。（当我添加另一个标题并尝试阅读时会发生同样的情况）

欢迎任何帮助，不便之处，敬请原谅。感谢

 class Item(object):

      def setup(self, config):
          self.config = config
          self.id = config['id']
          self.name = config['name']
          self.type = config['type']

  def create_item(config):
          new_item = Item()
          new_item.setup(config)
          return(new_item)
  def populate():
          all_items = {}
          f = open('test.txt', 'r')
          reader = csv.DictReader(f, delimiter = ',')
          for row in reader:
              new_item = (create_item(row))
              all_items[new_item.id] = new_item
          return(all_items)

输出：

things = populate()
things.keys()
dict_keys(['1'])

Python在csv.DictReader（）中返回KeyError
