What is an "operator"?

An "operator" is a symbol that does something in Python. It does an "operation".

Typically, an operator has values on the left and right side of it. These values are called "operands". An operand is any value an operator acts on.

For example, if I write the line 2 + 3, the plus sign (addition operator) is the operator, and the numbers (2 and 3) are the operands.

Categories of Operators

There are seven categories of operators in Python. They are:

• Arithmetic Operators
• Comparison Operators
• Logical Operators
• Bitwise Operators
• Assignment Operators
• Identity Operators
• Membership Operators

Arithmetic Operators

Useful for doing math with Python. You might need to use parentheses in conjunction with these arithmetic operators ((, )) if you want to enforce a specific order of operations.

• Addition Operator: +
• Subtraction Operator: -
• Multiplication Operator: *
• Division Operator: /
• Floor Division Operator: //
• Modulus Operator: %
• Exponentiation Operator: **

Comparison Operators

Used to compare two values. Each of these operators results in one of two boolean values (true or false).

• Equality Operator: ==
• Inequality Operator: !=
• Greater Than Operator: >
• Less Than Operator: <
• Greater Than or Equal To Operator: >=
• Less Than or Equal To Operator: <=

Bitwise Operators

Converts integers to their binary representation and then compares each corresponding pair of binary bits using the designated method. The resulting binary number is then translated back into decimal format.

• Bitwise AND Operator: &
• Bitwise OR Operator: |
• Bitwise XOR Operator: ^
• Bitwise NOT Operator: ~
• Bitwise Right Shift Operator: >>
• Bitwise Left Shift Operator: <<

Assignment Operators

• Assignment Operator: =
• Addition Assignment Operator: +=
• Subtraction Assignment Operator: -=
• Multiplication Assignment Operator: *=
• Division Assignment Operator: /=
• Modulus Assignment Operator: %=
• Floor Division Assignment Operator: //=
• Exponentiation Assignment Operator: **=
• Bitwise AND Assignment Operator: &=
• Bitwise OR Assignment Operator: |=
• Bitwise XOR Assignment Operator: ^=
• Bitwise Right Shift Assignment Operator: >>=
• Bitwise Left Shift Assignment Operator: <<=
• Walrus Operator: :=
