Kivy Escape Characters

Question

I have a .kv file containing among many widgets a label and I wish to contain a % symbol within the text string.

My string is currently in this format:

Label:
    text: 'Brightness: %s ' % int(s1.value) if s1.value else 'Slider not set'

and this works fine. However, I wish to add the % value after the value so that the string appears like this:

Brightness: 75 %

I have tried escaping the % character using \ and ' ' but I always receive the error:

ValueError: incomplete format

Answer 1

Use % to escape % ->

'Brightness: %s%% ' % int(s1.value) 

%% will always be ignored :)

Answer 2

Use %% to escape the % sign.

This has actually nothing to do with kivy, but with python, more exactly string formatting using the percent ( % ) sign.
