Here is my solution

I am joining the elements at the beginning and end of the list
using '+' operator any other solution, this is not looking
neater
I am a Linux user using python 2.7
You can use the % operator instead of +, and a generator
expression instead of map. It's a pretty small improvement,
though.
values = '||%s||' % ('||'.join(str(s) for s in value_list))
At least... I THINK you can use that generator expression in 2.7.
However you solve it, do yourself a favor and write a function to
encapsulate it:
def wrapped_join(values, sep):
"""Join values with sep, and also include sep at the ends."""
return "{sep}{vals}{sep}".format(sep=sep, vals=sep.join(str(v)
for v in values))
