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
