tip calculator not displaying proper dollar format

[Crackity]

I was wondering though if there is a certain situation[s] where one option is preferred over the other?

"{}".format(arg) is for formatting string and printing them. You'll receive a string when using it

whereas round(number,ndigits) is used to round off, it returns float which can further be used for calculations.

Ahh, that explains it! I almost posted it here but thought better of it, but after I finished the tip calculator and moved on to the next project I attempted to make use of both examples to verify that it worked the way I thought it would... and it didn't!

However your explanation... explains it!

On my next project I was supposed to have some user input and some set data, (non iterable??? ) then combine them and provide a grand total. I noticed that when I used the "round" option it printed $1000.0 instead of $1000.00. I went back and just used the "format" option instead, which seemed to fix it, but now realize that I had them reversed... Or did I?

Sorry just went back and double checked and thought I understood, but now am confused again. If I enter for example:

prep = 1000.00

does Python see that as a string or is it automatically defined as an integer or floating point due to the " . "?

If it still sees it as a string then mystery solved, but if it's already an integer by default then I don't know why the "round" option didn't work for me.

Either way I started this response to say thank you for all of your assistance!

And to Dead_EyE? Vielen Dank for deine hilfe mein freunde.
