If this is a list, then the strings are *ordered*. Why did you completely change your question? — Martijn Pieters, Sep 19 '13 at 08:45
I rolled back your edit; the new version has little relation to the old, invalidating my answer entirely. If you have a new problem, ask a new question. — Martijn Pieters, Sep 19 '13 at 08:47
Write down the question as it is, if those values are within a list, then write them as a list of strings. We are not psychic... — Mp0int, Sep 19 '13 at 08:56

If you have a list of strings, then strip each element of whitespace and use str.join() to join these together with a delimiter:

','.join([s.strip() for s in list_of_strings])

Demo:

>>> list_of_strings = ["1", "2", "3", "4", " ", "text1", "text2", "text3", "6", "first && second && third..", " ", " 7 ", " "]
>>> ','.join([s.strip() for s in list_of_strings])
'1,2,3,4,,text1,text2,text3,6,first && second && third..,,7,'

I *already* helped you with the question; you didn't ask anything new. I cannot lift any downvotes because I didn't downvote. – Martijn Pieters Oct 23 '13 at 08:41
