Python Program to Convert Binary to Gray Code

def binary_to_gray(n):
    """Convert Binary to Gray codeword and return it."""
    n = int(n, 2) # convert to int
    n ^= (n >> 1)
 
    # bin(n) returns n's binary representation with a '0b' prefixed
    # the slice operation is to remove the prefix
    return bin(n)[2:]
 
 
g = input('Enter binary number: ')
b = binary_to_gray(g)
print('Gray codeword:', b)
