Operators in python

Operators in Python perform operations on operands. There are unary, binary, and ternary operators. The document discusses arithmetic, assignment, relational, logical, boolean, and bitwise operators in Python. Arithmetic operators include addition, subtraction, multiplication, division, modulus, exponent, and integer division. Assignment operators assign values to variables like +=, -=, *=, /=, %=, **=, and //= . Relational, logical, boolean, and bitwise operators are also discussed.

Operators in Python Prakash G Khaire The Mandvi Education Society Institute of Computer Studies
Operator • An operator is a symbol that performs an operation. • An operator acts on some variables called operands. • If an operator acts on single variable, it is called unary operators • If an operator acts on two variables, then it is called binary operator • If an operator acts on three variables, then it is called ternary operator.
Types of operators in Python • Arithmetic Operators • Assignment Operators • Unary minus operator • Relational Operators • Logical Operators • Boolean Operators • Bitwise Operators
Arithmetic Operators Operator Meaning Example Result + Addition Operator. Adds two Values. a + b 7 - Subtraction Operator. Subtracts one value from another a – b 3 * Multiplication Operator. Multiples values on either side of the operator a * b 10 / Division Operator. Divides left operand by the right operand. a / b 2.5 % Modulus Operator. Gives reminder of division a % b 1 ** Exponent Operator. Calculates exponential power value. a ** b gives the value of a to the power of b a ** b 25 // Integer division, also called floor division. Performs division and gives only integer quotient. a // b 2 a = 5 b = 2
Assignment Operators Operator Example Meaning Result = z = x + y Assignment operator. Stores right side value into left side variable. z = 5 += z+=x Addition assignment operator. Adds right operand to the left operand and stores the result into left operand. z = 8 -= z-=x Subtraction assignment operator. subtracts right operand to the left operand and stores the result into left operand. z = 2 *= z*=x Multiplication assignment operator. Multiplies right operand to the left operand and stores the result into left operand. z = 15 /= z/=y Division assignment operator. Divides left operand with the right operand and stores the result into left operand. z = 2.5 %= z%=x Modulus assignment operator. Divides left operand to the right operand and stores the result into left operand. 2 **= z**=y Exponential assignment operator. Performs power value and then stores the result into left operands 25 //= z//=y Floor division assignment operator. Performs floor division and then stores 2 x = 3 y = 2 z = 5
