I would like to give some feedback about ...

From: https://py.checkio.org/mission/non-unique-elements/solve/ I already tested on my python idle, and works fine if 0 

for i in range(len(data)):
    if data.count(data[i])==1:
        print(str(data[i])+" : este no se repite")
        data2.insert(i,data[i])

for i in range(len(data2)):
    data.remove(data2[i])

print (data)
print (data2)
