Swap all odd and even bits Python

PROGRAM TO SWAP ALL ODD AND EVEN BITS

def swapBits(x) :

      

    # Get all even bits of x

    even_bits = x & 0xAAAAAAAA

  

    # Get all odd bits of x

    odd_bits = x & 0x55555555

      

    # Right shift even bits

    even_bits >>= 1

      

    # Left shift odd bits

    odd_bits <<= 1 

  

    # Combine even and odd bits

    return (even_bits | odd_bits) 

  

  

# Driver program

# 00010111

x = 23

  

# Output is 43 (00101011)

print(swapBits(x))




OUTPUT:

 43
