<class 'str'>
True
<class 'bool'>
True
<class 'str'>二，int函数

numInt = 10print("numInt值:", numInt, ",类型：", type(numInt))numFloat = float(numInt)print("numFloat值:", numFloat, ",类型：", type(numFloat))numStr = "3.1415"print("numStr值:", numStr, ",类型：", type(numStr))numFloat = float(numStr)print("numFloat值:", numFloat, ",类型：", type(numFloat))numBool = Trueprint("numBool值:", numBool, ",类型：", type(numBool))numFloat = float(numBool)print("numFloat值:", numFloat, ",类型：", type(numFloat)) |
运行结果:
numInt值: 10 ,类型： <class 'int'>
numFloat值: 10.0 ,类型： <class 'float'>
numStr值: 3.1415 ,类型： <class 'str'>
numFloat值: 3.1415 ,类型： <class 'float'>
numBool值: True ,类型： <class 'bool'>
numFloat值: 1.0 ,类型： <class 'float'>
