Answer explanation

The is operator is an identity operator, it checks whether both the operands refer to the same object or not. The p and q have equal values, stored in the same memory location, hence p and q are same. You can use id() function to check if the variables are same: print(id(p)) print(id(q)) which will indicate the same ID for both variables.
