Python pass elif

Question

我对python中的编码很陌生，并希望解决以下问题:如果状态为" new“或"Committed"，我希望返回名称，否则，我希望代码正在传递。在我的函数中，我传递一个JSON文件“更新”，其中包含关于状态和更改错误状态的人的姓名的数据。这些州是：“新”、“测试”、“承诺”和“已完成”。

def find_name(updates):
  for update in updates:
    #clear return value
    displayName= ''
    if 'fields' in update:
      fields = update['fields']
      if 'System.State' in fields:
        states = fields['System.State']
        if 'oldValue' not in states:
          if states['newValue'] == 'New':
              return update['displayName']
          elif (states['newValue'] == 'Committed'):
              return update['displayName']
          elif (states['newValue'] == 'Tested'):
              pass
      elif(states['newValue'] == 'Done'):
              pass
  return displayName

但是，如果这个州是经过“考验”或“完成”的，它并没有通过。有谁可以帮我？

如果状态与关键字and合并，则可以合并。要了解更多信息，请阅读本文章，这是为初学者准备的。python的一个更高级的特性是，您只需添加反斜杠就可以将一行缩短为新行。如果你不做一些事情，你就没有必要去做一个埃利夫。如果您想一步一步地分解我如何将请求合并为一个。评论一下！

def find_name(updates):
  for update in updates: 
    name = '' # reset the value of name to an empty string 
    if 'fields'       in update and \
       "System.State" in update['fields'] and \
       "oldValue" not in update['fields']['System.State']:
        # You can merge all your if statements into one large.
        # For readability you can put every and clause into it own line by adding a blackshlash to the end of the line 
        # technecally you can also merge the or statement into the first if but this would destroy the easy readability
        if update['fields']['System.State']['newValue'] == 'New' or update['fields']['System.State']['newValue'] == 'Committed':
            return update['name'] # upadte the name 
  return name
