What are operators? Give examples of some unary and binary operators.

Operators: Operators are symbols or keywords in a programming language that perform operations on operands (values or variables). They are used to manipulate data and perform calculations in expressions.

Examples of unary operators:

• Unary minus/negation: – (e.g., -x)
• Unary plus: + (e.g., +x)
• Increment: ++ (e.g., x++) [Note: Python does not have a built-in increment operator, but it can be achieved using other constructs.]

Examples of binary operators:

• Arithmetic operators:
  • Addition: + (e.g., x + y)
  • Subtraction: – (e.g., x – y)
  • Multiplication: * (e.g., x * y)
  • Division: / (e.g., x / y)
  • Modulo: % (e.g., x % y)
  • Exponentiation: ** (e.g., x ** y)
  • Floor division: // (e.g., x // y)
• Comparison operators:
  • Equal to: == (e.g., x == y)
  • Not equal to: != (e.g., x != y)
  • Greater than: > (e.g., x > y)
  • Less than: < (e.g., x < y)
  • Greater than or equal to: >= (e.g., x >= y)
  • Less than or equal to: <= (e.g., x <= y)
