# Binary numbers in Python

## Binary numbers in Python

You can convert between a string representation of the binary using bin() and int()

``````>>> bin(88)
0b1011000
>>> int(0b1011000, 2)
88
>>>

>>> a=int(01100000, 2)
>>> b=int(00100110, 2)
>>> bin(a & b)
0b100000
>>> bin(a | b)
0b1100110
>>> bin(a ^ b)
0b1000110
``````

I think youre confused about what binary is. Binary and decimal are just different representations of a number – e.g. 101 base 2 and 5 base 10 are the same number. The operations add, subtract, and compare operate on numbers – 101 base 2 == 5 base 10 and addition is the same logical operation no matter what base youre working in. The fact that your python interpreter may store things as binary internally doesnt affect how you work with it – if you have an integer type, just use +, -, etc.

If you have strings of binary digits, youll have to either write your own implementation or convert them using the int(binaryString, 2) function.

#### Binary numbers in Python

If youre talking about bitwise operators, then youre after:

``````~ Not
^ XOR
| Or
& And
``````

Otherwise, binary numbers work exactly the same as decimal numbers, because numbers are numbers, no matter how you look at them. The only difference between decimal and binary is how we represent that data when we are looking at it.
