Operator meaning explanation

[Sherine]

It's just the old way of allowing you to substitute the values of those variables for the placeholders (%s and %d) in the string, as the output shows. These days, you should be using f-strings, though.

Thank you so much , I learn new thing outside the book.

print("%s result as %d" % (name, score))
is old style print statement, you should use f-string:
print(f"{name} result as {score}")

Thank you so much, learn new thing. it means my book is old version..
