set,list,tuple之間的互換

~~~
In [1]: a = set()

In [2]: b=[1,2,3,4,12,3,1,2]

In [3]: c = set(b)

In [5]: c
Out[5]: {1, 2, 3, 4, 12}
~~~

~~~
In [6]: d=list(c)

In [7]:

In [7]: d
Out[7]: [1, 2, 3, 4, 12]
~~~
~~~
In [8]: e= tuple(d)

In [9]: e
Out[9]: (1, 2, 3, 4, 12)
~~~

~~~
In [10]: f = list(e)

In [11]: f
Out[11]: [1, 2, 3, 4, 12]
~~~

~~~
In [12]: g= set(e)

In [13]: g
Out[13]: {1, 2, 3, 4, 12}
~~~

使用set，可以快速的完成對list中的元素去重復的功能
