類的函數屬性綁定給不同對象，是不同的綁定方法。對象調用綁定方法時會把對象本身當做self參數傳入

示例代碼

class People:
    country = ‘China‘
?
    def __init__(self, name, sex, age):
        self.Name = name
        self.Sex = sex
        self.Age = age
?
    def test(self):
        print(self)
?
?
conan = People(‘Conan‘, ‘male‘, 8)
wukong = People(‘
 
wukong‘, ‘male‘, 18)
?
wukong.test()  # People.test(wukong)
conan.test()   # People.test(conan)
?
print(People.test,People.test(123))
print(wukong.test,wukong.test())
print(conan.test,wukong.test())

打印結果：

# <__main__.People object at 0x10813a320>
# <__main__.People object at 0x10813a2e8>
# <function People.test at 0x1081291e0>
 

# <bound method People.test of <__main__.People object at 0x10813a320>>
# <bound method People.test of <__main__.People object at 0x10813a2e8>>
