How to turn a list/tuple into a space separated string in python using a single line?

I tried doing:

str = ""
"".join(map(str, items))

but it says str object is not callable. Is this doable using a single line?

Answer

Use string join() method.

List:

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

Tuple:

>>> t = ("a", "b", "c")
>>> " ".join(t)
'a b c'
>>> 

Non-string objects:

>>> l = [1,2,3]
>>> " ".join([str(i) for i in l])
'1 2 3'
>>> " ".join(map(str, l))
'1 2 3'
>>>
