Python supports multiple assignments in a single statement:

a, b, c = "Polar bear", 12, 5.5

Python likewise allows the assignment of one value to several variables in a single statement:

a = b = c = "high cube"

num = item = sum = 27

add and +=

The ‘add and’ operator adds the value of the left and right operands and assigns the total to the left operand.

x += 4

y += x

subtract and - =

The ‘subtract and’ operator subtracts the value of the right operand from that of the left and assigns the difference to the left number.

x -= y

a -= 4

multiply and *=

The ‘multiply and’ operator multiplies the left and right operands and assigns the product to the left operand.

x *= z

a *= 4

divide and /=

x /= c

y /= 4

modulos and %=

The ‘modulos’ and operator divides the value of the left operand with the right

operand then assigns the remainder to the left.

x %= a

x %= 3

floor division and //=

The ‘floor division and’ operator performs a floor division of the left operand by the right operand and assigns the result to the left operand.

x //= a

x //= 2

Relational or Comparison Operators

Relational operators evaluate a comparative expression and return either True or False.

Python provides the following relational operators:
