Combining elements of a list in python to a single element

Question

list:

['a','b']

Expected List:

['a,b']

Is there a pythonic way to do this?

Can you give us a longer example? There are many ways to do it for the current example. Basically, we want to see whether the list is populated only by strings, or lists of lists with strings, etc. — Reti43, Apr 06 '16 at 19:44

l2 = [','.join(l)]

There's not much point to wrapping this output in a list, though. It'd probably make more sense to just get the string:

joined_string = ','.join(l)

You can use str.join

>>> l = ['a','b']
>>> [', '.join(l)]
['a, b']
