How to make textbutton "[lst[index_number]]" work? [SOLVED]

[Luxliev]

Code: Select all

init python:
    my_string = "string"
    lst = [my_string]
    index_number = 0
    
screen testscreen:
    # textbutton "[lst[index_number]]"       # this gives me TypeError: list indices must be integers, not unicode
    textbutton "[lst[0]]"                    # this works

How can I make number that is variable inside another square bracket work correctly with textbutton?

I think you will have to use a temporary variable prior to the string interpolation

$ button_text = lst[index_number]
textbutton "[button_text]"

Ren'py is a bit fussy with doing some python code within the interpolation, so putting that outside (pre-doing it) is often the easiest way

Yeah I can do that but it's only fix for simple problem if I want to access list of class inside other list then code will quickly become messy.

Bracket interpolation (which is renpy-specific) just doesn't support it. You can use python's own interpolation, or use an intermediary variable as Remix suggested.
