浅谈Python的深拷贝和浅拷贝 在python中,创建一个变量例如a=10,即直接赋值:其实就是对象的引用。 一、浅拷贝 copy浅拷贝,没有拷贝子对象,所以原始数据改变,子对象会改变(浅拷贝只copy第一层),通俗的理解是:拷贝了引用,并没有拷贝内容 值得注意的是:浅拷贝在拷贝可变类型的数据时会只拷贝最表层,而对于不可变类...

No. Python’s slicing syntax (e.g., some_list[:]) applies to sequence types like lists, tuples, or strings, not dictionaries. For shallow dictionary copying, you can use dict.copy(), the dict() constructor, or other methods like {k: v for k, v in original_dict.items()}. Will ...
python-浅拷贝和深拷贝 浅拷贝和深拷贝 简述 深浅拷贝的差异仅对复合对象有意义,比如列表,类实例。 浅拷贝 拷贝的副本共享内部对象的引用的拷贝为浅拷贝 举个栗子 通过类构造函数对list1进行了浅拷贝,通过id(list1)和id(list2)可知list1与list2是两个不同的对象, 但是list1和list2共享内部对象的引用(由list1...
