to be the same as the sign of the second Decimal value.

```

Code #1 : Example for copy_sign() method

 `# Python Program explaining ``# copy_sign() method`` ` `# loading decimal library``from` `decimal ``import` `*`` ` ` ` `# Initializing a decimal value``a ``=` `Decimal(``-``1``)`` ` `b ``=` `Decimal(``'0.142857'``)`` ` `# printing Decimal values``print` `(``"Decimal value a : "``, a)``print` `(``"Decimal value b : "``, b)`` ` ` ` `# Using Decimal.copy_sign() method``print` `(``"\n\nDecimal a with copy_sign() method : "``, a.copy_sign(a))`` ` `print` `(``"Decimal a with copy_sign() method : "``, a.copy_sign(b))`` ` `print` `(``"Decimal b with copy_sign() method : "``, b.copy_sign(a))`

Output :

```Decimal value a :  -1
Decimal value b :  0.142857

Decimal a with copy_sign() method :  -1
Decimal a with copy_sign() method :  1
Decimal b with copy_sign() method :  -0.142857

```

Code #2 : Example for copy_sign() method

 `# Python Program explaining ``# copy_sign() method`` ` `# loading decimal library``from` `decimal ``import` `*`` ` ` ` `# Initializing a decimal value``a ``=` `Decimal(``'-3.14'``)`` ` `b ``=` `Decimal(``'321e + 5'``)`` ` `# printing Decimal values``print` `(``"Decimal value a : "``, a)``print` `(``"Decimal value b : "``, b)`` ` ` ` `# Using Decimal.copy_sign() method``print` `(``"\n\nDecimal a with copy_sign() method : "``, a.copy_sign(a))`` ` `print` `(``"Decimal a with copy_sign() method : "``, a.copy_sign(b))`` ` `print` `(``"Decimal b with copy_sign() method : "``, b.copy_sign(a))`

Output :

```Decimal value a :  -3.14
Decimal value b :  3.21E+7

Decimal a with copy_sign() method :  -3.14
Decimal a with copy_sign() method :  3.14
Decimal b with copy_sign() method :  -3.21E+7
