When you use the copy module, Python creates a field-for-field copy of an object, bypassing the standard construction mechanism, which normally involves calling the .__init__() method. Instead, Python creates a blank instance of the same type and copies attributes from the original object’s...
copy()函数是Python中的一个内置函数,用于创建一个对象的浅拷贝。浅拷贝是指创建一个新的对象,但是该对象的元素仍然是原始对象的引用。换句话说,浅拷贝只复制了对象的引用,而不是对象本身。 copy()函数的语法如下: 代码语言:txt 复制 new_object = copy.copy(old_object) ...
python deep copy and shallow copy Python中对于对象的赋值都是引用,而不是拷贝对象(Assignment statements in Python do not copy objects, they create bindings between a target and an object.)。对于可变对象来说,当一个改变的时候,另外一个不用改变,因为是同时的,也就是说是保持同步的。 此时不想让他们...
