Numeric Data and Operators

Numeric Data Type

int (integer)

float

complex

Special symbols that perform operations on variables and values
Types: Assignment, Arithmetic, Comparison, Logical, Bitwise, Membership, Identity

Examples

a = 10 b = 3 calc_1 = 3 + 2 print(calc_1) my_calc = a + 3 * (4 - 1) print(my_calc) calculation = (a + b) * (a - b) / 4 print(calculation)

Performs mathematical operations on numeric data

Operator	Name	Description	Expression	Result
+	Addition	Add two numbers	`3 + 2`	5
-	Subtraction	Subtract one number from another	`5 - 1`	4
*	Multiplication	Multiply two numbers	`4 * 2`	8
/	Division	Divide one number by another	`7 / 4`	1.75
//	Floor Division	Divide and round down to nearest integer	`10 // 3`	3
%	Modulus	Remainder after division	`10 % 3`	1
**	Exponent	Raise a number to the power of another	`2 ** 3`	8

Arithmetic operators in Python

Assigns values to variables. Can also perform an operation and assignment in one step

Operator	Name	Description	Expression	Result
=	Simple Assignment	Assigns value on right to variable on left	`x = 5`	Equivalent to `x = 5`
=	Multiple Assignment	Assigns same value to multiple variables	`x = y = z = 10`	Equivalent to `x = 10; y = 10; z = 10`
=	Positional Assignment	Assigns multiple values to multiple variables	`a, b, c = 1, 2, 3`	Equivalent to `a = 1; b = 2; c = 3`
+=	Add and Assignment	Adds value on right to variable on left	`x += 5`	Equivalent to `x = x + 5`
-=	Subtract and Assignment	Subtracts value on right from variable on left	`x -= 5`	Equivalent to `x = x - 5`
*=	Multiply and Assignment	Multiplies value on right to variable on left	`x *= 5`	Equivalent to `x = x * 5`
/=	Divide and Assignment	Divides variable on left by value on right	`x /= 5`	Equivalent to `x = x / 5`
//=	Floor Divide and Assignment	Floor divides variable on left by value on right	`x //= 5`	Equivalent to `x = x // 5`
%=	Modulus and Assignment	Takes modulus of variable on left by value on right	`x %= 5`	Equivalent to `x = x % 5`
**=	Exponent and Assignment	Raises variable on left to power of value on right	`x **= 5`	Equivalent to `x = x ** 5`

Assignment operators in Python

Compares two values and return a boolean result (True or False)

Operator	Name	Description	Expression	Result
==	Equal to	Returns True if both operands are equal	`5 == 5`	True
!=	Not equal to	Returns True if both operands are not equal	`5 != 5`	False
<	Less than	Returns True if left operand is less than right operand	`5 < 10`	True
>	Greater than	Returns True if left operand is greater than right operand	`10 > 5`	True
<=	Less than or equal	Returns True if left operand is less than or equal to right one	`5 <= 5`	True
>=	Greater than or equal	Returns True if left operand is greater than or equal to right one	`10 >= 5`	True

Comparison operators in Python

Combines multiple conditional statements and return a boolean result

Operator	Name	Description	Expression	Result
and	Logical AND	Returns True if both operands are True	`(5 < 10) and (4 > 5)`	True
or	Logical OR	Returns True if at least one operand is True	`(5 < 10) or (4 > 5)`	True
not	Logical NOT	Reverses the result of the operand	`not (5 < 10)`	False

Logical operators in Python

Checks if a value is a member of a sequence (string, list, tuple, set, dictionary)

Operator	Name	Description	Expression	Result
in	Membership Test	Returns True if value is found in the sequence	`"a" in "cat"`	True
not in	Membership Test	Returns True if value is not found in the sequence	`"cat" not in ["cat", "rat"]`	False
