Arithmetic Operators

Arithmetic operators are used for performing mathematical operations.

  • +: Addition
  • -: Subtraction
  • *: Multiplication
  • /: Division
  • %: Modulus (remainder)
  • **: Exponentiation
  • //: Floor Division (quotient, rounded down to the nearest whole number)

Comparison Operators

Comparison operators are used to compare values.

  • ==: Equal to
  • !=: Not equal to
  • >: Greater than
  • <: Less than
  • >=: Greater than or equal to
  • <=: Less than or equal to

Logical Operators

Logical operators are used to combine or modify Boolean values.

  • and: Logical AND (True if both operands are True)
  • or: Logical OR (True if at least one operand is True)
  • not: Logical NOT (inverts the Boolean value)

Assignment Operators

Assignment operators are used to assign values to variables.

  • =: Assigns the value on the right to the variable on the left
  • +=: Adds the right operand to the left operand and assigns the result to the left operand
  • -=: Subtracts the right operand from the left operand and assigns the result to the left operand
  • *=: Multiplies the left operand by the right operand and assigns the result to the left operand
  • /=: Divides the left operand by the right operand and assigns the result to the left operand
  • %=: Computes the modulus of the left operand and the right operand and assigns the result to the left operand
  • **=: Calculates the exponentiation of the left operand by the right operand and assigns the result to the left operand
  • //=: Performs floor division on the left operand by the right operand and assigns the result to the left operand
  • := (Walrus Operator): Assigns a value to a variable as part of an expression

Bitwise Operators

Bitwise operators perform operations on binary representations of numbers.

  • &: Bitwise AND
  • |: Bitwise OR
  • ^: Bitwise XOR (exclusive OR)
  • ~: Bitwise NOT (complement)
  • <<: Left Shift
  • >>: Right Shift

Membership Operators

Membership operators are used to test if a value is present in a sequence.

  • in: Returns True if a value is found in the sequence
  • not in: Returns True if a value is not found in the sequence

Identity Operators

Identity operators are used to compare the memory location of two objects.

  • is: Returns True if both variables point to the same object
  • is not: Returns True if both variables point to different objects

Nice! You should make one for JavaScript

Sure! I’ll make one right now!

I think we need to add a small introduction and examples of using operators.

you can never forget the walrus teeth.

You forgot many operators such as ternary conditional, unpacking (part of displays), matrix multiplication, subscription, calling, attribute reference.

I know it’s a wiki but I’m too lazy to edit it

I had no idea ** was even a thing…like ever…not even in JS :open_mouth:
