Is there a way to create multiline comments in Python?
...
In Python 2.7 the multiline comment is:

>>> t = ((1,'a'),(2,'b'))
>>> {y:x for x,y in t}
{'a':1, 'b':2}

How can I generate a unique ID in Python? [duplicate]

Your usage wouldn't work that way (at least not in 2.7): you'd need to call unique_sequence.next().

How to properly ignore exceptions
...: https://youtu.be/OSGv2VnC0go?t=43m23s
My addition to this is the Python 2.7 equivalent:
