  2. # Output: <type 'str'>
  4. print(type([]))
  5. # Output: <type 'list'>
  7. print(type({}))
  8. # Output: <type 'dict'>
  10. print(type(dict))
  11. # Output: <type 'type'>
  13. print(type(3))
  14. # Output: <type 'int'>

id()函数返回任意不同种类对象的唯一ID，举个例子：

  1. name = "Yasoob"
  2. print(id(name))
  3. # Output: 139972439030304
