Boolean
Programming basics[1]
In most computer programming languages, a Boolean data type is a data type with only two possible values: true or false.[2]
By convention we can express true as the integer 1 and false as the integer 0 (zero). Please be careful as some programming languages treat an empty or unset value as FALSE.
Example[edit]
In PHP:
<?php
$myFirstVar = True; // assign the value TRUE to $myFirstVar
$myOtherVar = False; // assign the value FALSE to $myOtherVar
?>
In Python:
myFirstVar = True
myOtherVar = False
