Assignment Operators

What are Assignment Operators

Generally in programming, assignment operators are those operators(symbols) that are used to assign a value to a variable.

Basic Assignment operator

Basic assignment operator represented by = assigns the value on the its right to a variable on its left

Example

example of basic assignment operator

  >>>
  >>> #
  >>> x = 10
  >>>
  >>> #
  >>> x
  10
  >>>
  >>> #
  >>> x = 20
  >>>
  >>> x
  20
  >>>

Addition Assignment operator

Addition assignment operator symbolised by += adds the operand(value) on its right to the variable or property on its left, and assigns the result to the variable or property on its left.

Example

example of addition assignment operator

  >>>
  >>> #
  >>> x = 18
  >>>
  >>> #
  >>> x += 2
  20
  >>>

Subtraction Assignment operator

Subtraction assignment operator symbolised by -= subtracts the operand(value) on its right from the variable or property on its left, and assigns the result to the variable or property on its left.

Example

example of subtraction assignment operator

  >>>
  >>> #
  >>> x = 20
  >>>
  >>> #
  >>> x -= 10
  10
  >>>

Multiplication Assignment operator

Multiplication assignment operator symbolised by *= multiply the operand(value) on its right by the variable or property on its left, and assigns the result to the variable or property on its left.

Example

example of multiplication assignment operator

  >>>
  >>> #
  >>> x = 10
  >>>
  >>> #
  >>> x *= 2
  20
  >>>

Division Assignment operator

Division assignment operator represented by /= divides the variable or object on the its left by the operand(value) on its right, and then assigns the result to the variable or object on its left

Example

example of division assignment operator

  >>>
  >>> #
  >>> x = 10
  >>>
  >>> x
  10
  >>>
  >>>
  >>> x /= 2
  >>>
  >>> #
  >>> x
  5.0
  >>>

Floor Division Assignment operator

Floor-Division assignment operator represented by //= divides the variable or object on the its left by the operand(value) on its right, and then assigns the result to the variable or object on its left

Example

example of floor dividion assignment operator

  >>>
  >>> #
  >>> x = 10
  >>>
  >>> #
  >>> x
  10
  >>>
  >>> x //= 2
  >>>
  >>> #
  >>> x
  5
  >>>

Modulus Assignment operator

Division assignment operator represented by %= divides the variable or object on the its left by the operand(value) on its right, and then assigns the result to the variable or object on its left

Example

example of modulus assignment operator

  >>>
  >>> #
  >>> x = 9
  >>>
  >>> x
  9
  >>>
  >>> #
  >>> x %= 2
  >>>
  >>> x
  1
  >>>
