is not true. In the program, the value assignment statement calculates the expression x + 2 on the right, returns 10, and then assigns the variable x. Since the value before x is 8, after the value is re-assigned, the value of x becomes 10. It is very important to understand the representation of variables in computer memory. For example, the following statements declare variables and assign values. A = "ABC" The Python interpreter does two things: A constant is a variable tha
