Why does it have red squiggly lines under it if it works perfectly fine and no errors happen when I run it?

The direct answer is that your terminal program must be broken.  it
should not use "squiggly lines" for any purposes.

But perhaps you're not seeing this in terminal, but in some text editor.
Better specify what that is.

As for the "Syntax Error..."   Better supply the entire traceback.  I
can't see how you consider that error message as "working."

Better give it a different name, since you're using this same name as a
local within the function.

This line does nothing, as has been pointed out before in other
messages. of yours.  You're not printing it, assigning it to something,
calling it, or whatever.

There's no such function.

No such function.

You're using recursion when a simple loop is called for.
