Python Decimal to Octal Conversion – This tutorial explains the logic of decimal number to octal number conversion process. It also explains the Python code to convert a dcimal nuber into octal number.

How to Convert a decimal Number to Octal Number

- We divide the decimal number by base 8 and get the quiotient and remainder. Example: divide 119 by 8, quotient1 is 17 and remainder1 is 7.
- Then we divide the quotient by base 8 and get the quotient and remainder. The Example continues from step 1: divide quotient1 by 8, quotient2 is 1 and remainder2 is 6.
- This process continues until the quotient bcomes zero. The example continues from step 2: divide quotient2 by 8, now quotient3 is 0 (zero), so we stop, and remainder3 is 1.
- Now we write all remainders in reverse order to get the required binary number. The example continus from step 3. We will write remainder3 = 1,remainder2=6,remainder1=7 (in reverse order) so that we will get the required binary number 167.

## The Source code of python Program Decimal to Octal Number Conversion

# This Python script / program is used to input # a decimal number and convert into octal number # using a while loop # author: www.EasyCodeBook.com (c) num = int(input('Enter a Decimal number to Convert into Octal:')) q=num octal=0 i=0 while q!=0: rem = q%8 octal = octal + rem * (10**i) q = q // 8 i+=1 print('Octal Number=',octal)

The output of python program for decimal number to octal conversion is as follows: Enter a Decimal number to Convert into Octal:119 Octal Number= 167
