Python Program for Octal To Binary Conversion
Octal To Binary Conversion in Python
Here, in this page we will discuss the program for octal to binary conversion in Python . 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.
Method 1:-
- Accept octal number
- Convert it into decimal Equivalent
- Convert this decimal value into Binary
Make sure you have visited these two pages before moving ahead with the code –
Method 1 Code in Python
Run
def convert(octal): i = 0 decimal = 0 while octal != 0: digit = octal % 10 decimal += digit * pow(8, i) octal //= 10 i += 1 print("Decimal Value :", decimal) binary = 0 rem = 0 i = 1 while decimal != 0: rem = decimal % 2 decimal //= 2 binary += rem * i i *= 10 print("Binary Value :", binary) octal = int(input("Octal Value : ")) convert(octal)
Output
Octal Value: 12
Decimal Value: 10
Binary Value: 1010
Method 2
Each digit of an octal number can be converted into its binary Equivalent (see image)
Binary Representation for Octal digit:
- 0 => 000
- 1 => 001
- 2 => 010
- 3 => 011
- 4 => 100
- 5 => 101
- 6 => 110
- 7 => 111
Method 2 Code in Python
Run
def convert(octal): print("Equivalent Binary Number: ", end="") for i in range(len(octal)): switcher = { 0: "000", 1: "001", 2: "010", 3: "011", 4: "100", 5: "101", 6: "110", 7: "111" } print(switcher.get(int(octal[i]), "Invalid Octal Number"), end="") octal = list(input("Insert an octal number: ")) convert(octal)
Output
Insert an octal number: 347
Equivalent Binary Number: 011100111
