There are two ways:

The first way:

A = range (100) random_num = random.randint (0Magne99) print random_num a.insert (random_num,random_num) number = [i for i in an if a.count (I) = = 2] print number [0]

The second way is ordinary traversal.

Print "*" * 10 res = [] for i in a: if i not in res: res.append (I) else: print I # print res

Both of the above methods can be ergodic.
