# Python program for octal to decimal conversion

## Octal To Decimal Conversion

Here, in this page we will discuss the program for octal to decimal conversion in python . Octal numbers are also called numbers with base 8 and hold values from 0 – 7. Whereas in Decimal numbers are with base 10 is Standard number system for denoting integers and non-integers. In programing languages octal numbers are represented with 0o/0O[zero and o/O] in prefix and decimal numbers are represented as normal integer representation.
In this python program we will convert octal numbers into Decimal numbers or from a number with base 8 to number with base 10. ## Algorithm

• Step 1:- Start.
• Step 2:- Take a octal number with prefix 0o[zero and o/O].
• Step 3:- Use int() to convert octal to decimal number.
• Step 4:- Print number.
• Step 5:- End. ## Program for Octal to decimal conversion in Python

```#take octal number
#with prefix 0o[zero and o/O]
oct_num = 0o512
#convert octal number to integer
#integers are with base 10
deci_num = int(oct_num)
#print number
print('Number after conversion is :' + str(deci_num))```
```Output:
Number after conversion is :330```
