Numeric types: int, float, complex string tuple frozen set 常見的mutable objects: list dict set byte array Case One >>>a=[1, 2, 3]>>>id(a)4317018016>>>a[1]=10>>>id(a)4317018016>>>a[1, 10, 3] 列表的值在a[1] = 10 執行後被改變,但是其地址空間沒有改變。 Case Two >>>a=1...

python中的不可变对象有以下几种: int float decimal complex bool string tuple range frozenset bytes mutable对象 与immutable对象对应的就是mutable对象,也就说对象的值是可变的,例如我我们熟知的append函数。 l =[] l.append(1)print("After l.append(1), the address of l:", id(l))...

NSString是Objective-C中表示字符串的类,而AutoreleasingUnsafeMutablePointer是Swift中表示自动释放的可变指针的类型。要将NSString转换为AutoreleasingUnsafeMutablePointer,可以使用桥接方法来实现。 在Swift中,可以使用bridge方法将NSString转换为AutoreleasingUnsafeMutablePointer。具体步骤如下: 首先,创建一个NSString对象,例如...
Tuples are not the only immutable data type in Python, but they are a great tool to learn because they can be directly compared to lists, which are mutable. Other immutable data types are: int float decimal complex bool string tuple ...
