Logical operators

Logical operators are used to check different conditions and execute the code accordingly. For example, detecting a button interfaced to the Raspberry Pi's GPIO being pressed and executing a specific task as a consequence. Let's discuss the basic logical operators:

• EQUAL: The EQUAL (==) operator is used to compare if two values are equal:

       >>>3==3 
       True 
       >>>3==2 
       False

• NOT EQUAL: The NOT EQUAL (!=) operator compares two values and returns True if they are not equal:

       >>>3!=2 
       True 
       >>>2!=2 
       False

• GREATER THAN: This operator (>) returns True if one value is greater than the other value:

       >>>3>2 
       True 
       >>>2>3 
       False

• LESS THAN: This operator compares two values and returns True if one value is smaller than the other:

       >>>2<3 
       True 
       >>>3<2 
       False

• GREATER THAN OR EQUAL TO (>=): This operator compares two values and returns True if one value is greater/bigger than or equal to the other value:

       >>>4>=3 
       True 
       >>>3>=3 
       True 
       >>>2>=3 
       False

• LESS THAN OR EQUAL TO (<=): This operator compares two values and returns True if one value is smaller than or equal to the other value:

       >>>2<=2 
       True 
       >>>2<=3 
       True 
       >>>3<=2 
       False
