I have this string:
string = '9x3420aAbD8'
How can I turn string into:
'023489ADabx'
What function would I use?

You can just use the built-in function sorted to sort the string lexicographically. It takes in an iterable, sorts each element, then returns a sorted list. Per the documentation:
sorted(iterable[, key][, reverse])Return a new sorted list from the items in iterable.
You can apply that like so:
>>> ''.join(sorted(string))
'023489ADabx'
Since sorted returns a list, like so:
>>> sorted(string)
['0', '2', '3', '4', '8', '9', 'A', 'D', 'a', 'b', 'x']
Just join them together to create the desired string.

This is the best and only way to do it.
You can use the sorted() function to sort the string, but this will return a list
sorted(string)
['0', '2', '3', '4', '8', '9', 'A', 'D', 'a', 'b', 'x']
to turn this back into a string you just have to join it, which is commonly done using ''.join()
So, all together:
sorted_string = ''.join(sorted(string))
