Code #1 : Example for logical_invert() method

 `# Python Program explaining ``# logical_invert() method`` ` `# loading decimal library``from` `decimal ``import` `*`` ` ` ` `# Initializing a decimal value``a ``=` `Decimal(``'0'``)`` ` `b ``=` `Decimal(``'1'``)`` ` `# printing Decimal values``print` `(``"Decimal value a : "``, a)``print` `(``"Decimal value b : "``, b)`` ` ` ` `# Using Decimal.logical_invert() method``print` `(``"\n\nDecimal a with logical_invert() method : "``, a.logical_invert())`` ` `print` `(``"Decimal b with logical_invert() method : "``, b.logical_invert())`

Output :

```Decimal value a :  0
Decimal value b :  1

Decimal a with logical_invert() method :  1111111111111111111111111111
Decimal b with logical_invert() method :  1111111111111111111111111110
