Python – K length decimal Places
• Last Updated : 05 Sep, 2020

Given a Decimal Number, extent its digits to K length.

Input : num = 76.8, K = 5
Output : 76.80000
Explanation : Length of decimal places is 5.

Input : num = 76.8, K = 6
Output : 76.800000
Explanation : Length of decimal places is 6.

Method : Using format()

This is way in which this task can be done. In this, we harness multiple format compatibilites to perform task of getting appropriate length of decimal places.

## Python3

 `# Python3 code to demonstrate working of ``# K length decimal Places``# Using format()`` ` `# initializing number ``num ``=` `76.8`` ` `# printing original number ``print``(``"The original number is : "` `+` `str``(num))`` ` `# initializing K ``K ``=` `7`` ` `# using format to solve this problem``res ``=` `"{{:.{}f}}"``.``format``(K).``format``(num)`` ` `# printing result ``print``(``"The resultant number : "` `+` `str``(res))`
Output
```The original number is : 76.8
The resultant number : 76.8000000
