在Python中，可以使用字典和列表来进行按类型分组收集的操作。

例如，有一个包含多个对象的列表，每个对象都有一个'类型”属性。我们可以使用字典来按照类型将这些对象进行分组：

objects = [
  {"name": "apple", "type": "fruit"},
  {"name": "banana", "type": "fruit"},
  {"name": "carrot", "type": "vegetable"},
  {"name": "spinach", "type": "vegetable"},
  {"name": "beef", "type": "meat"},
  {"name": "chicken", "type": "meat"}
]

grouped_objects = {}

for obj in objects:
  if obj["type"] not in grouped_objects:
    grouped_objects[obj["type"]] = []
  
  grouped_objects[obj["type"]].append(obj)

print(grouped_objects)

这个代码将输出以下内容：

{
  "fruit": [
    {"name": "apple", "type": "fruit"},
    {"name": "banana", "type": "fruit"}
  ],
  
  "vegetable": [
    {"name": "carrot", "type": "vegetable"},
    {"name": "spinach", "type": "vegetable"}
  ],
  
  "meat": [
    {"name": "beef", "type": "meat"},
    {"name": "chicken", "type": "meat"}
  ]
}

这将按照类型对对象进行分组，让我们可以更方便地对它们进行处理。
