我在建一個班暖氣。此類的每個實例都具有屬性“temperature”。Heating還必須支持將屬性“temperature”打印為整數的temperature（）方法。在

當我調用temperature（）方法時，我得到錯誤“int”對象不可調用，因為自身溫度已定義為整數。在

我怎么解決這個問題？在

代碼：class Heating:

"""

>>> machine1 = Heating('radiator kitchen', temperature=20)

>>> machine2 = Heating('radiator living', minimum=15, temperature=18)

>>> machine3 = Heating('radiator bathroom', temperature=22, minimum=18, maximum=28)

>>> print(machine1)

radiator kitchen: current temperature: 20.0; allowed min: 0.0; allowed max: 100.0

>>> machine2

Heating('radiator living', 18.0, 15.0, 100.0)

>>> machine2.changeTemperature(8)

>>> machine2.temperature()

26.0

>>> machine3.changeTemperature(-5)

>>> machine3

Heating('radiator bathroom', 18.0, 18.0, 28.0)
