"foo" alone as a boolean operator is an equivalent length check,

No, you are not missing something, but the casual reader may want to take
note that if foo: serves only as a "is not None or is zero" check.

So if foo is not None: is a more robust check for that singular condition.

That's all, just an aside.         Thanks.       --Fred
