PROGRAM TO CONVERT BINARY NUMBER TO DECIMAL NUMBER

def binaryToDecimal(n):

    num = n;

    dec_value = 0;

      

    # Initializing base 

    # value to 1, i.e 2 ^ 0

    base1 = 1;

      

    len1 = len(num);

    for i in range(len1 - 1, -1, -1):

        if (num[i] == '1'):     

            dec_value += base1;

        base1 = base1 * 2;

      

    return dec_value;

  

# Driver Code

num = "10101001"; 

print(binaryToDecimal(num));
