Display "$" sign together with a float number

Question

Hi I want to have my display to be for example, Single room 4 $720.00 But I do not know how to have the dollar sign there without having the error that it doesn't go with a float value.

single_room = int(input("Number of Single room: "))
total_single = 90 * single_room
print(f'{"Single room":<12}{single_room:^3}{"$" + total_single:>9.2f}')

This is an error because string doesn't go along with the float value. Please assist

You need the dollar sign to be as part of the string itself, not as part of a variable... `f'{"Single room":<12}{single_room:^3}${total_single:>9.2f}'` — Tomerikoo, Apr 13 '21 at 19:20
Umm, sorry if this is a dumb question, but - I don't understand your print. Can you add an explanation of what the print line is supposed to do ? — TheEagle, Apr 13 '21 at 19:21
@Programmer It says in the question, it's supposed to print `Single room 4 $720.00` — Tomerikoo, Apr 13 '21 at 19:22
@Tomerikoo Hi, I tried to add the dollar sign there but it doesn't align to the right hand side — Cruz, Apr 13 '21 at 19:22

@Tomerikoo I know this, but I wanted to understand his code (`f'{"Single room":<12}{single_room:^3}{"$" + total_single:>9.2f}'`) ... — TheEagle, Apr 13 '21 at 20:04

so you're f-string interpolating:

print(f"${total_single}")

should work, try and adapt it to your problem. The $ is not part of the variable

But it's just a individual statement without the other details that I've included – Cruz Apr 13 '21 at 19:21

so... add the other details? I don't understand what the difficulty is. – Karl Knechtel Apr 13 '21 at 19:33

If you want the price to be aligned to the right together with the $ sign, you can format in two steps:

single_room = int(input("Number of Single room: "))
total_single = f"${90 * single_room:.2f}"
print(f'Single room {single_room:^3}{total_single:>9}')

Example run:

Number of Single room: 4
Single room  4   $360.00

First, format the $ together with the price as a string into total_single. Then, align it as you want in the final string.
