tip calculator not displaying proper dollar format

[syogun]

If you just want to output a string for dollar, i18n is overkill.
In this case the normal formatting method is the easiest way to solve the problem quickly.

fmt = '$ {:.2f}'
value = 1.1337
final_string = fmt.format(value)
print(final_string)

# or shorter
print('$ {:.2f}'.format(value))

# since python 3.6 with format strings
print(f'{value:.2f}')

The curly braces are replaced by the variable. The text after the colon is the format specifier.
