Answer 2

the expression *a is a[:]* returns False, since *a[:]* creates a (deep)copy of the list *a* with a different id / identity / reference (memory address).

*is* operator checks for identity.

checking for equality with *a == a[:]* returns True, since both lists have equal elements.

Answer 3

id(a) is not equal to id(a[:])
