If you don't understand an error message, google it: SyntaxError: positional argument follows keyword argument - Google Search[^]
Every link there explains why it happens.

So then look at your code: is there anywhere where a positional argument follows any keyword arguments? I.e., is there an argument of the form ... myArg = myargvalue, myvalue, ...?
Yes:

Python

color = 'positive', 'death',

Either make the 'death' argument keyword, or move it.

You should expect to get syntax errors every day, probably many times a day while you are coding - we all do regardless of how much experience we have! Sometimes, we misspell a variable, or a keyword; sometimes we forget to close a string or a code block. Sometimes the cat walks over your keyboard and types something really weird. Sometimes we just forget how many parameters a method call needs.

We all make mistakes.

And because we all do it, we all have to fix syntax errors - and it's a lot quicker to learn how and fix them yourself than to wait for someone else to fix them for you! So invest a little time in learning how to read error messages, and how to interpret your code as written in the light of what the compiler is telling you is wrong - it really is trying to be helpful!

So read this: How to Write Code to Solve a Problem, A Beginner's Guide Part 2: Syntax Errors[^] - it should help you next time you get a compilation error!

Solution 2

You should make more use of the documentation, which explains exactly what the problem is: 4. More Control Flow Tools — Python 3.11.0 documentation[^].
