Python: Operators
Input values are called operands.
An operation is an action or procedure which produces a new value from one or more operands.
An operator is a symbol that represents an operation. For example: +, x, /, *, //, **
There are two types of operators: unary and binary.
The unary operator operates only on one operand, for example 'negation' - changing the sign of a value.
The binary operator operates on two operands for example addition, subtraction, multiplication, division, exponentiation, etc.
Consider the expression 2 + 7
operands: 2 and 7
operator: +
The operator catagories:

Relational or Comparison Operators
