[issue29297] python3 open() does not check argument type before attempting to read() or write()

Serhiy,

I expected a type error or a filenotfound like you received, however mine doesn't return the same. It just hangs.  I've attached a picture.  Also, I meant this to be for 3.6 not 3.5.

>>> test = False
>>> with open(test) as f:
...     fail = f.read()
...
