# F-string- f"xxxxxx {}" is another great function which simplifies the conversion of data, as we have seen in the above examples, so if we have many different data types, we don't need to convert them one by one to print it as a string. see below;
#print (f"your score is {score}")

#If the bill was $150.00, split between 5 people, with 12% tip.
