This guy: :=
Allows you to define a variable at the same time that you’re doing something with it. For example:
if my_var := other_var.do_things() is not None: …
Now you can use the variable within the if block and don’t need to add an extra line before or after that line to assign the value. Personally I don’t like it since it messes up my flow when I’m reading the code back, but a lot of people like the time save.
