list去除重复

1. [代码][Python]代码 简单去重     

?

1 2 3 4 5

l = [1,2,3,3] l = list(set(l))   >>>l >>>[1,2,3]

2. [代码][Python]代码 不变序去重(可反排)     

?

1 2 3 4 5 6 7 8 9 10 11

def sets(L,M='L'):     B = []     if M=='R':         L = L[::-1]     for x in L:         if x not in B:             B.append(x)     return B if __name__ == '__main__':     A = [1,2,1,3,7,4,9,6,9,5,10,9,4,1,1,1,1,1,1]     print sets(A,'R')
