1、isinstance(param1,param2)
例子:
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | def confirmType(variate): varType=None if isinstance(variate,str): varType= "str" elif isinstance(variate,int): varType= "int" elif isinstance(variate,float): varType= "float" elif isinstance(variate,tuple): varType= "tuple" elif isinstance(variate,dict): varType= "dict" elif isinstance(variate,set): varType= "set" elif isinstance(variate,tuple): varType= "list" return varType |
2、通过与已知类型的常量进行比较
例子：
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | def confirmType(variate): varType= "" if type(variate) == type('str'): varType= "str" elif type(variate) == type(1): varType= "int" elif type(variate) == type(12.3): varType= "float" elif type(variate) == type({"key1"}): varType= "set" elif type(variate) == type([1]): varType= "list" elif type(variate) == type(()): varType= "tuple" elif type(variate) == type({"key1":"123"}): varType= "dict" return varType |
补充:
isinstance() 与 type() 区别：
- type() 不会认为子类是一种父类类型，不考虑继承关系。
- isinstance() 会认为子类是一种父类类型，考虑继承关系。
如果判断两个类型是否相同推荐使用 isinstance()。
