def decimalToBinary(n):  
    return bin(n).replace("0b", "")  
    
# Driver code  
if __name__ == '__main__':  
    print(decimalToBinary(8))  
    print(decimalToBinary(18))  
    print(decimalToBinary(7))  
    
Output:

	count = 0

	#reverse the string
    binaryVal = binaryVal[::-1]

    #go through the list and get the value of all 1's
	for i in range(0, len(binaryVal)):
    	if(binaryVal[i] == "1"):
            count += 2**i
    
    return count
