- Arithmetic Operators
- Relational Operators
- Logical 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 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`

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`
