First off, be aware that this won't make a unique file name. But if
you're okay with that (deal with collisions somehow), then sure.

Instead of using str(), use strftime():
>>> now = datetime.datetime.now()
>>> str(now)
'2016-02-10 12:34:26.377701'
>>> now.strftime("%Y-%m-%d-%H-%M-%S-%f")
'2016-02-10-12-34-26-377701'
You could instead use some other format string if you like. Here's your options:
