python type
type() 用于获取对象类型的。

  1.  type(object) -> the object's type

测试

  2. class ClassTest:
  3.     # declare a integer type variable
  4.     var_int = 12
  6.     # declare a string type variable
  7.     var_str = 'monday'
  9.     # declare a tuple type variable
  10.     var_tup = (1, 2, 'mono')
  12. # it will show the ClassTest as a 'type'
  13. print('Type of ClassTest :', type(ClassTest))
  15. ct = ClassTest
  17. # it will show the ClassTest as a 'class'
  18. print('Type of ct :', type(ct))
  20. # it will print the type of var_int as 'int'
  21. print('Type of var_int :', type(ct.var_int))
  23. # it will print the type of var_str as 'str'
  24. print('Type of var_str :', type(ct.var_str))
  26. # it will print the type of var_tup as 'tuple'
  27. print('Type of var_tup :', type(ct.var_tup))

功能
