♦ An operator is a special symbol or keyword in Python that tells the computer to perform a specific operation on one or more
values, called operands.
♦ A binary operator in Python is a type of operator that works on two operands to perform an operation.
♦ Arithmetic operators are used to perform mathematical operations, including addition, subtraction, multiplication, division,
modulus, exponentiation and floor division.
♦ Logical operators are used to perform logical operations on two or more conditions.
♦ Identity operators are used to determine whether two variables point to the same object in memory.
♦ A simple statement in Python is a statement that is written in a single line and completed by pressing the Enter key.
♦ Type conversion in Python is the process of changing a value from one data type to another, ensuring that operations and
calculations work correctly.
