I first came across as= serts when using Wing IDE. See "Helping Wing Analyze Code" [1] ex= plains why using assert and isinstance will let Wing IDE autocomplete thing= s it otherwise couldn't.

Py= Charm uses docstrings to accomplish the same task [2] but can also use asse= rts/isinstance [3].


I use PyCharm. Than= ks for [2], it's a keeper
