A counter is also used to track how many objects share the data. When the program wants to modify an object, it can determine if the data is shared (by examining the counter) and can do a deep copy if needed. Lazy copy looks to the outside just as a deep copy, but takes advantage of the speed of a shallow copy whenever possible.
A Java example, when "copying" an object using simple assignment: Object original = new Object (); Object copy = null ; copy = original ; // does not copy object but only its reference The object is not duplicated, the variables 'original' and 'copy' are actually referring to the same object.
Each element of a slice is a shallow copy. In Python, a distinction between expressions and statements is rigidly enforced, in contrast to languages such as Common Lisp, Scheme, or Ruby. This leads to duplicating some functionality. For example: List comprehensions vs. for-loops; Conditional expressions vs. if blocks

Copy-on-write (COW), also called implicit sharing [1] or shadowing, [2] is a resource-management technique [3] used in programming to manage shared data efficiently. Instead of copying data right away when multiple programs use it, the same data is shared between programs until one tries to modify it.
