types模塊中定義了Python中所有的類型,包括NoneType, TypeType, IntType, FloatType, BooleanType, BufferType, BuiltinFunctionType, BuiltinMethodType, ClassType, CodeType, ComplexType, DictProxyType, DictType, DictionaryType等。
Python內建函數type(object),用於返回當前object對象的類型。例如:
>>> type(1) <type 'int'> >>> type("1")
<type 'str'>
>>> type(True)
<type 'bool'>
>>> type(2.3)
<type 'float'>
>>> type(1+3j)
<type 'complex'>
>>> type(type(2))
<type 'type'>
>>> type(type)
<type 'type'>
實現方法很簡單,把對應的類型賦值給變量:
NoneType = type(None) TypeType = type ObjectType = object IntType = int LongType = long FloatType = float BooleanType = bool
StringType = str
因此,在我們的代碼中可以這樣來使用:
>>> import types >>> type(1)==types.IntType True >>> type("1")==types.StringType True
