A string can be used as a separator to join a list of strings together into a
single string using the join()
method. For example you can create a string
where each element in a list is separated by a space.
>>> " ".join(["once","upon","a","time"])
"once upon a time"
The following example separates the string elements with three hyphens.
>>> "---".join(["once", "upon", "a", "time"])
"once---upon---a---time"
