def sort_string(a)
return ''.join(sorted(a))
Is there a way to sort string without using join()?

You can perform the join manually one letter at a time, but why wouldn't you want to use `join`? – interjay Nov 14 '15 at 10:24

@binarysubstrate that gives the answer he starts with. Of course, I agree with interjay: why don't you want to use join? That is a very pythonic way of doing it. – Foon Nov 14 '15 at 13:42

I'm voting to close this question as off-topic because use `str.join` here is the best solution. – Remi Guan Nov 15 '15 at 01:27

Your solution is correct as strings are immutable in python. So, it's impossible to change (in your case - sort) an existing string. You have to create new one (you do it with join() call).
