Explain like I'm five this line of python code.

first_name = Tammy print("Have a great day {}!".format(first_name))

I'm not sure how this line of code works. I understand that I'm using a method (or function) of print but I'm not getting why it's doing it. I understand that it works but I don't get the logic.

Why wouldn't the code be written like this: print("Have a great day" (first_name)!""

Whilst the results may look the same, the operation is not.

.format() isn't a method of print() but of str (the string object). So what this means is that every string you have, has a set of methods like this one. .format() let's you update the content of a string by placing something else inside it.

The other approach is concatenation, adding two strings together. There is no difference in performance, most people using Python tend to prefer using format as it's found to be easier on the eyes. You could use either and both will have the same outcome.
