if you are simply workig in SoloLearn you can do as follows:
input1 = input()
input2 = input()
you can now input multiple things. only need to put each on a new line in the input popupbox.
you then only need to write a format for what goes where, but this isnt really efficient.
i just read your last message, the method above works for random input that needs to go at the bottom of an invoice. and is really as simple as I wrote above.
Because there isn’t any code to go off from, I am spitballing here.

I am not good with OOP yet, but perhaps thinking that way might help you out
