In all probability, what is required is just: a.split(','); no for, no print
And unfortunately none of the answers (that I see) describe the spectrum of
what one may really want
a.split(',')
set(a.split(','))
Less likely (in this case) but important for a learner to be aware of:
Counter(a.split(',')
And if the original 'a' looked something like
>>> a="p:1,q:2,r:42"
then you probably want something like:
>>> {k:v for item in a.split(',') for k,v in [item.split(':')]}
{'q': '2', 'p': '1', 'r': '42'}
>>>
In all cases the print is irrelevant and unnecessary
And if we insist on interpreting the OP request for replacing comma by newline
(almost always a misconceived request), one can do:
>>> a="p,q,r"
>>> str(a.replace(',','\n'))
'p\nq\nr'
Sure one can go one step further and do:
>>> print str(a.replace(',','\n'))
p
q
r
But this is almost always not what the requester wants (even if he thinks it is)

Those who teach that programming needs to start with writing print statements
are the same except for not having the excuse of being kids]
