Sintax Error

[JamilMGomez]

Hello, I`m trying to run the script but every time it shows this error and nothing changes:

File "labwc-gtktheme.py", line 36
     color.append(f"@{tokval}")
                             ^
Syntax Error: invalid syntax

What version of python are you running?

Just had a look. Seems like f-strings are supported from v3.6

Alternative "@{}".format(tokval) or just "@" + tokval in case you want to support Python < 3.6 as well.
