Recap
A data type specifies the type of value a variable can contains.
Comments enable us to understand the way a program works.
Operators can be defined as special symbols which perform arithmetic and logical
computation.
Arithmetic operators perform arithmetic operations between two operands.
Assignment operators are used to assign the value of the right expression to the left operand.
Relational operators are used to compare the value of the two operands and returns True or
False accordingly.
Precedence of operators determines the order in which the operators are executed.
