Just do it:
去做就对了：
In [1]: s = "http://www.stackoverflow.com"
In [2]: f = {s}
In [3]: type(f)
Out[3]: builtins.set
In [4]: f
Out[4]: {'http://www.stackoverflow.com'}

set()class Return a new set or frozenset object whose elements are taken from iterable , and strings are iterable! you can put your string in a listor tuple. for refuse of fragmentation !
set()class 返回一个新的 set 或frozenset 对象，其元素取自 iterable ，字符串是iterable! 你可以把你的字符串放在 alist或tuple. 拒绝碎片化！
>>> set([sample])
set(['http://www.stackoverflow.com'])
>>> set((sample,))
set(['http://www.stackoverflow.com'])

The easiest way is final = {sample}.
最简单的方法是final = {sample}。
