Python Programming with Raspberry Pi

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: ...
