# Python Program for Octal To Binary Conversion

## Octal To Binary Conversion

Numbers with base 8 are called octal numbers and uses digits from 0-7 for representation of octal number.Where as numbers with base 2 are called binary numbers  and it uses 0 and 1 for representation of binary numbers.In python when a number starts from 0o[zero and o/O], it is considered as octal number and same with binary if a number starts with 0b[zero and b/B] it is called binary number. In this Python program we will convert a number with base 8 to number with base 2 ie, from octal to binary. ## Algorithm

• Step 1:- Start.
• Step 2:- Take numbers with prefix 0o[zero and o/O].
• Step 3:- Use in-built function, bin() to convert octal number to binary number.
• Step 4:- Print the binary representation of the number. ## Python program to convert octal to binary

```#octal number with prefix 0o/0O
oct_num = 0o564
#using bin() to convert octal number to binary
bin_num = bin(oct_num)
#print binary Number
print('Number after conversion is :' + str(bin_num))```
`Output:Number after conversion is :0b101110100`
