# Python operators

• Arithmetic Operators
• Relational Operators
• Logical Operators

## Arithmetic Operators

Arithmetic operators perform all mathematical operations like addition, subtraction, multiplication, and division.

 1 + Add two operand 2 - Subtract one operand from another 3 * Perform multiplication of two operand 4 / Perform division and calculate the floating quotient 5 // Perform division and calculate the integer quotient 6 % Perform division and calculate the remainder 7 ** Calculate the power of a given number

Example:  save the file as arithmetic.py

`print(2+3)  # 5`
`print(3-2)   # 1`
`print(3*2) # 6`
`print(3/2) # 1.5`
`print(3//2) # 1`
`print(3%2) # 1`
`print(3**2) # 9`

## Relational operators

Relational operators check the relation between two operands and return boolean value depends upon conditions.

 1 < Less than 2 <= Less than or equal 3 > Greater than 4 >= Greater than or equal 5 != Not equal 6 == equality

Example save the file as relational_operators.py

`print(3<2) # False`
`print(3<=2) # False`
`print(3>2) # True`
`print(3>=2) # True`
`print(3!=2) # True`
`print(3==2) # False`

## Logical operators

 1 and Return true if all conditions are true otherwise false. 2 or Return true if one of the conditions is true otherwise false. 3 not Return invert of the result of a given condition.

Example: Save the file as logical_operators.py

Example 1 (and operator)

`email_validate=False`
`mobile_validate=True`
`if (email_validate==True and mobile_validate==True):`
`           print("You can buy now.")`
`else:`
`           print("Sorry, you can't buy, please verify the email or mobile number.")`

`Output: Sorry, you can't buy, please verify the email or mobile number.`

Example 2 (or operator)

`driving_licence=True`
`passport=False`
`if (driving_licence==True or passport==True):`
`           print("You can open your bank account")`
`else:`
`           print("Sorry, you can't open your bank account")`

`Output: You can open your bank account. `

Example 3 (not operator)

`name=input("What is your name?")`
`if(not name):`
` print("Please fill up name")`
`else:`
` print("Your name is ",name)`

`Output: `
`What is your name?`
`Please fill up your name`

`What is your name? John`
`Your name is John`
