For example:

class FooBar:
    def __init__(self):
        self.a: int = None
        self.foo: str = None

Is this bad practice/go against PEP guidelines or is it fine?

foo[0] is also unsafe unless foo is known to be nonempty, ofc.

Technically correct , the best kind of correct.

foo.lower() would have been a better example.
