What exactly is being fixed here? It looks more like conversion to a oneliner?

Previous:

	def appendToStringWithSeparator(self, str, part):
		if str == "":
			str = part
		else:
			text = f"{text}{self.separatorChar or ' '}{part}"
		return text

With this commit:

	def appendToStringWithSeparator(self, text, part):
		return f"{text}{self.separator or ' '}{part}" if text else part

There are 2 NameErrors.

str -> text
self.separatorChar -> self.separator
