排序一：去重位置不变

>>>a=[22,12,3,45,4,4,3,0,32,9]>>>b=[]>>>[b.append(h) for h in a if not h in b]>>>print b[22, 12, 3, 45, 4, 0, 32, 9]

排序2：去重位置改变

>>> a[22, 12, 3, 45, 4, 4, 3, 0, 32, 9]>>> c=list(set(a))>>> c[0, 32, 3, 4, 9, 12, 45, 22]

排序3:排序sort和倒序reverse

>>> a[22, 12, 3, 45, 4, 4, 3, 0, 32, 9]>>> a.sort()>>> a[0, 3, 3, 4, 4, 9, 12, 22, 32, 45]>>>>>>>>> a[0, 3, 3, 4, 4, 9, 12, 22, 32, 45]>>> a.reverse()>>> a[45, 32, 22, 12, 9, 4, 4, 3, 3, 0]
