Python Type Hinting - Method Returns a List of the Current Class

Use a string literal for a forward reference:

@staticmethod
def from_file(fname: str, verbose : bool = False)->List['CareerTransition']:
    #Do some stuff
    pass

An even nicer way then writing the concrete class as stated by @chepner is to use the literal __class__. The whole thing would look like this:

@staticmethod
def from_file(fname: str, verbose : bool = False) -> List['__class__']:
    # Do some stuff
    pass
