不加括號

class Bank_account():
    def password(self):
        return "password:123"

andy = Bank_account()
print(andy.password)

不加括號，輸出結果

<bound method Bank_account.password of <__main__.Bank_account object at 0x0000012C834FF520>>

加括號

class Bank_account():
    def password(self):
        return "password:123"

andy = Bank_account()
print(andy.password())

加括號，輸出結果

password:123

我的理解是
不加括號是去查看該物件綁定的方法
加括號是去查看該物件的方法內容
想請問各位大大們，我的理解是否有誤，煩請指正

延伸題 @property

class Bank_account():
    @property
    def password(self):
        return "password:123"

andy = Bank_account()
print(andy.password)

andy.password = "password:456"
print(andy.password)

預期的錯誤

password:123
Traceback (most recent call last):File "D:/, line 9, in <module> andy.password = "password:456" AttributeError: can't set attribute

若將第7行加上括號

print(andy.password())
則出現如下錯誤

Traceback (most recent call last):File "D:/", line 7, in <module>
print(andy.password()) TypeError: 'str' object is not callable

想請教為何遇到@property後，就不加括號；表示在讀取屬性時僅能查看?!
再請大大們指正了~
謝謝
