what is the difference between a shallow copy and deep copy in python?
user
a shallow copy in python is a bit-wise copy of an object. it creates a new object which stores the reference of the existing object. it does not create a copy of nested objects, instead it just copies the reference of nested objects. a deep copy creates a copy of object as well as of nested objects. in deep copy, a copy of object is copied in other object. it means that any changes made to a copy of object do not reflect in the original object.  in deep copy, a copy of object is copied in other object. it means that any changes made to a copy of object do not reflect in the original object.
