self.values
is optional parameter (List) in my class.
I have the following code:
self.values.append(area) if self.values else self.values = [area]
This produce
SyntaxError: can't assign to conditional expression
I know I can fix this by doing:
if self.values: self.values.append(area) else: self.values = [area]
But isn’t there a shorter way to set it?

You can do the following, using the fact as it the list is None
or empty, it’s evaluated as false and the other operand of the OR
expression will be used
self.values = (self.values or []) + [area]
